Emergence agitation (EA) is more commonly observed after thoracic surgeries and can lead to serious complications. This study aimed to evaluate the effectiveness of serratus anterior plane block (SAPB) combined with oxycodone for transitional analgesia in preventing EA after video-assisted thoracoscopic surgery (VATS). A total of 121 adult patients scheduled for VATS under one-lung ventilation anesthesia were enrolled and randomly divided into three groups: preoperative SAPB without opioids for transitional analgesia near the end of the surgery (SAPB + SAL group, n = 39); preoperative SAPB with sufentanil at 0.1 µg/kg for transitional analgesia (SAPB + SF group, n = 42); and preoperative SAPB with oxycodone at 0.1 mg/kg for transitional analgesia (SAPB + OCD group, n = 40). In primary outcomes, the incidences of EA in the SAPB + SAL, SAPB + SF, and SAPB + OCD groups were 38.5%, 28.6%, and 7.5% respectively. There was a statistically significant difference in EA incidence between the SAPB + OCD and SAPB + SF groups (P = 0.0136). In secondary outcomes, compared to the SAPB + SF group, the SAPB + OCD group experienced shorter tracheal extubation time [15(9, 25) min vs. 21.5(14.5, 32.5) min; P = 0.0473] and PACU stay [67.5(55.0, 85.0) min vs. 87.5(70.0, 110.0) min; P = 0.0026]; lower NRS scores at 15 min and 2 h post-extubation (P < 0.01), and higher Quality of Recovery-15 (QoR-15) scores post-surgery [113(98, 123) vs. 102(88, 112); P = 0.0122]. Our results suggest SAPB combined with oxycodone for transitional analgesia, compared with sufentanil, is more effective in preventing EA after VATS and conductive to rapid recovery postoperatively.

Introduction: Thoracic surgery is associated with an 8–10% incidence of postoperative pulmonary complications (PPCs). Introduction of minimally invasive Video-assisted thoracoscopic surgery (VATS) aimed to reduce pain related and pulmonary complications. However, PPCs remain a common cause of morbidity after VATS. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was searched for VATS lobectomy cases from 2017 to 2021 with General Anesthesia (GA) as the primary anesthetic technique. Cases were stratified into four groups—GA alone, GA+local, GA+Regional and GA+Epidural. Generalized linear regression models were used to examine whether PPCs differ by anesthetic technique, controlling for morbidity risk factors. The study's primary outcome was the occurrence of any PPC (pneumonia, reintubation or prolonged mechanical ventilation). The secondary outcome was length of hospital stay (LOS). Results: A total of 15,084 VATS lobectomy cases were identified and 14,477 cases met inclusion criteria. The PPC rate was between 3.5–5.2%. There was no statistically significant difference in the odds of PPCs across the groups. Compared to the GA alone group, the regional and local group had significantly shorter LOS (9.1% and 5.5%, respectively, both ps <.001), whereas the epidural group had significantly longer LOS (18%, p <.001). Conclusion: Our analysis suggests that the addition of regional or local anesthesia is associated with shorter LOS after VATS lobectomy. However, these techniques were not associated with lower PPC incidence. Future randomized controlled trials could help to elucidate the best anesthetic technique to reduce pain and enhance recovery.

This work aims to describe the evolution of the video-assisted Thoracoscopic Surgery (VATS) approach from a multiportal access to a biportal access for thoracic herniated disc surgery. Thoracic disc herniation remains a challenging pathology for spine surgeons. VATS of the thoracic spine was described in the 90s and represented an important technical leap by including minimally invasive options for thoracic pathology. Nowadays, VATS in thoracic surgery tends to evolve towards an even less invasive technique, from a multiportal approach to a biportal one. We describe the adoption of this approach for our spinal pathology in 3 patients. We use a two-port VATS. The largest (approximately 5 cm) with an Alexis retractor and a second port (1.5 cm) just for the camera. The 3 patients started walking in less than 24 hours and none suffered any complications related to the approach. All of them reported tolerable pain at the surgical site. Changing our previous VATS system from 3 to 5 ports was relatively easy regarding the surgical technique. This access allows the surgeon to manipulate the instrumentation confidently and the camera does not fog up as often. Extracting a piece of rib is unnecessary and theoretically, we only manipulate 1 or at most 2 intercostal nerves, so the patient's recovery is favorable. [ABSTRACT FROM AUTHOR]

This study aimed to conduct a systematic review and meta‐analysis comparing video‐assisted thoracoscopic surgery (VATS) and open thoracotomy (OT) in the context of pulmonary metastasectomy. Three databases were assessed. The primary outcome was overall survival. The secondary outcomes were recurrence‐free survival, ipsilateral recurrence, and hospital length of stay (LOS). Hazard ratios (HRs), odds ratios (ORs), and mean difference (MD) with 95% confidence intervals (CIs) were calculated. Reconstruction of time‐to‐event data and sensitivity analyses were performed for the primary endpoint. After screening, 11 studies were included encompassing 2159 patients undergoing lung metastasectomy (VATS: 827; OT: 1332). Compared to OT, patients who underwent VATS had higher overall survival rates (HR 0.75; 95% CI 0.67–0.85; p < 0.01), no significant difference in recurrence‐free survival (HR 1.07; 95% CI 0.88–1.29; p = 0.48), shorter hospital LOS (MD −1.99 days; 95% CI −2.59 to −1.39; p < 0.01), and no significant difference in ipsilateral recurrence rates (OR 0.86; 95% CI 0.52–1.42; p = 0.56). For patients undergoing pulmonary metastasectomy, VATS strategy is associated with higher survival rates and reduced hospital LOS when compared with OT. Moreover, metastasis recurrence does not seem to be associated with long‐term mortality in this population. [ABSTRACT FROM AUTHOR]

Lung resection surgery, which is performed as a treatment for lung cancer and metastatic lung tumors, is currently conducted via minimally invasive techniques such as video-assisted thoracoscopic surgery and robot-assisted methods. Postoperative complications related to this surgery, such as pulmonary vein thrombosis and cerebral and other organ infarctions, have been increasingly reported. The primary cause of these complications is thrombus formation in the pulmonary vein stump. Statistical data on the site of lung lobectomy have indicated that surgeries involving the left upper lobe are most frequently associated with embolic complications. Although this issue has not received considerable attention in anesthesiology, the importance of prevention and treatment in postoperative management is growing. The role of anesthesiologists in preventing these complications is critical. These roles involve careful fluid management to avoid hypercoagulable states, consideration of early postoperative anticoagulation therapy, assessment of the suitability of epidural anesthesia for postoperative anticoagulation, and improvement of hospital-wide safety systems and monitoring of high-risk patients. Anesthesiologists need to understand the pathology and risk factors involved and play an active role in preventing and treating these complications through effective collaboration with thoracic surgeons and the in-hospital stroke team.

Introduction: Chronic post-surgical pain (CPSP) remains a prevalent issue following video-assisted thoracic surgery (VATS), despite advancements in surgical techniques. Various regional anesthesia techniques, including thoracic paravertebral block (PVB), intercostal nerve block (ICNB), serratus anterior plane block (SAPB), erector spinae plane block (ESPB), and thoracic epidural anesthesia (TEA), have been employed in VATS procedures to mitigate this issue. This study aims to compare the efficacy of these analgesia methods in reducing the incidence of CPSP in VATS patients through a network meta-analysis. Methods: A systematic search was conducted in PubMed, the Cochrane Library, and EMBASE for randomized controlled trials (RCTs) comparing the incidence of CPSP associated with PVB, ICNB, SAPB, ESPB, and TEA. The occurrence of CPSP was evaluated at both 2–3 months and 6 months post-surgery. Results: Six RCTs, involving 652 patients, were included in the analysis of CPSP incidence at 2–3 months, while seven RCTs, involving 715 patients, were included for 6 months analysis. PVB, ICNB, or TEA reduced CPSP incidence compared with control group (without regional anesthesia techniques) at both 2–3 months and 6 months post-surgery. However, SAPB was found less effective in reducing CPSP incidence at 2–3 months post-VATS compared to PVB, ICNB, or TEA. Conclusions: PVB, ICNB, and TEA exhibit significant effects on reducing CPSP incidence following VATS. Conversely, SAPB is not recommended for reducing CPSP incidence post-VATS. Nonetheless, considering the limitation of a small sample size in this network meta-analysis, additional RCTs are necessary to validate these conclusions and enhance the management of CPSP after VATS.

The article discusses the use of endobronchial valves (EBVs) for treating persistent air leaks (PALs) in children with necrotizing pneumonia. The study, conducted at four pediatric hospitals, found that EBVs were effective in managing PALs in children, with most patients showing improvement or resolution of the air leak. The procedure was well-tolerated, and EBVs were successfully removed in the majority of cases. The study suggests that EBVs can be a minimally invasive and safe method for managing PALs in children with necrotizing pneumonia, potentially avoiding more invasive surgical interventions.

Objective: We aimed to evaluate the efficacy of rhomboid intercostal block (RIB) for analgesia management in patients who underwent video-assisted thoracoscopic surgery. Methods: Adult patients who underwent VATS under general anesthesia between July 2020 and June 2022 were included in the study. There was two groups in this study: RIB (n = 25) vs control (n = 25) group. RIB was performed with 30 ml 0.25% bupivacaine at the end of the surgery. Surgical intercostal blockade was performed with 30 ml 0.25% bupivacaine in the control group. The patients received intravenous fentanyl patient-controlled postoperative analgesia. The numerical rating score (NRS), opioid consumption, and adverse events were recorded. Results: A total of 50 patients were randomized into 2 groups. There were no significant difference in terms of the demographic data between groups (P > 0.05). Postoperative opioid consumption at 0–8, 8–16, 16–24, and 24–48 h and rescue analgesic use were significantly lower in RIB group (P < 0.05). At all times, the static/dynamic NRS were significantly lower in RIB group. The rate of nausea and itching was higher in control group (P < 0.05). Conclusion: US-guided RIB provides effective post-VATS analgesia. [ABSTRACT FROM AUTHOR]

Background: Accurate preoperative localization is a challenge in thoracoscopic surgery for multiple pulmonary nodules. In this study, we aimed to assess the accuracy and feasibility of electromagnetic navigation (EN)-guided percutaneous localization. Methods: We enrolled 50 patients with multiple pulmonary nodules for EN-guided (EN group) or CT-guided (CT group) localization. The primary outcome was the localization accuracy, and the primary analysis was to assess the noninferiority (noninferiority margin of 5 mm) of EN-induced localization deviation compared with that of CT-induced deviation. The secondary outcomes included the procedural duration, anxiety score, and incidence of complications. Results: Among the 50 patients randomized to the EN- and CT-guided groups, 24 patients (53 nodules) underwent EN-guided preoperative marking, and 25 patients (54 nodules) underwent CT-guided preoperative marking. The demographic, clinical, and radiological characteristics did not differ significantly between the groups (P > 0.05). Among these patients, the EN group was noninferior in terms of localization deviation compared with the CT group (9.0 [6.5] vs. 7.5 [6.0] mm; P = 0.33; absolute difference 0.9 [95% CI] 0.03–1.77]). Furthermore, the procedural duration was 16.3 (4.2) minutes for the EN group and 22.3 (8.2) minutes for the CT group (P = 0.002). Additionally, the EN group exhibited significant improvements compared with the CT group on the basis of the Amsterdam Preoperative Anxiety and Information Scale, particularly in relation to the S and C subscales' cumulative scores. Conclusions: EN was found to be noninferior to CT in terms of localization accuracy, as it significantly decreased the procedural duration and relieved psychological stress for patients who underwent simultaneous surgery for multiple pulmonary nodules.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is an exceedingly rare tumor with unique clinicopathological features, posing major diagnostic challenges. Case presentation: We present a case of a 74-year-old woman with a lung nodule incidentally detected in the right middle lobe (RML) through 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging. Through comprehensive evaluations by thoracic surgeons, she underwent video-assisted thoracic surgery of RML lobectomy to excise the lung nodule. Subsequent histopathological and immunohistochemical analyses confirmed the nodule as HCCC. She was discharged without any postoperative complications. No recurrence has been observed after two years of follow-up. This case underscored the importance of comprehensive imaging modalities and pathological analysis in the management of primary pulmonary HCCC. Conclusions: This report highlights the critical role of imaging techniques and pathological analysis in diagnosing primary pulmonary HCCC, with this case demonstrating the essential value of 18F-FDG PET/CT integration.

Leiomyosarcoma is a soft‐tissue sarcoma that accounts for less than 1% of all malignant tumors. Furthermore, leiomyosarcoma accounts for 6% of all soft tissue sarcomas, and leiomyosarcoma of azygos vein origin is extremely rare. In this report, we describe a case of leiomyosarcoma derived from an azygos vein that was completely resected. A 78‐year‐old male patient was incidentally found to have a mediastinal mass during a computed tomography (CT) scan performed for the evaluation of prostate cancer. Bronchoscopic needle biopsy revealed the mass to be a leiomyosarcoma. Preoperative contrast‐enhanced CT demonstrated a filling defect in the azygos vein, suggesting the tumor's origin from this structure. Video‐assisted thoracoscopic surgery (VATS) was performed to resect the mediastinal tumor. The tumor was found to have minimal adhesions to surrounding tissues and no evidence of local invasion, although findings suggested it originated from the azygos vein. Consequently, en bloc resection of the azygos vein was performed. Postoperative histopathological examination confirmed the diagnosis of leiomyosarcoma originating from the azygos vein, and complete resection was performed. [ABSTRACT FROM AUTHOR]

Objectives: This study assesses the safety and efficacy of using indocyanine green (ICG) for preoperative CT‐guided localization of multiple pulmonary nodules. Methods: We included patients who underwent CT‐guided preoperative ICG localization followed by video‐assisted thoracoscopic surgery (VATS). Four primary outcomes were evaluated: technical success, pneumothorax, pulmonary hemorrhage, and postoperative hospital stay (PHS). Patients were classified into single nodule and multiple nodules groups, with further subgroups based on the side of localization including unilateral and bilateral subgroups. Univariate and multivariate analyses were used to evaluate risk factors for PHS and pneumothorax. Results: A total of 374 patients (54.8 ± 11.4 years, 99 with multiple nodules). The success rate in the multiple nodules group was 98.3%, similar to single nodules. Apart from PHS, no significant differences were observed in outcomes between patients with single and multiple nodules. Longer PHS was observed for patients with multiple nodules (3 [2–4] days vs. 3 [3–4] days, p = 0.022). Multivariable analysis indicated longer stays were associated with pulmonary hemorrhage during localization, surgical blood loss, postoperative complications, and non‐segmentectomy procedures. Advanced age emerged as the sole independent risk factor for pneumothorax. The success rate in the unilateral subgroup and the bilateral subgroup was 97.8% and 99%, respectively, with higher pneumothorax rates in the unilateral subgroup (38.3% vs. 20%). Conclusion: CT‐guided preoperative ICG localization of multiple pulmonary nodules is safe and effective. It can be applied to both unilateral and bilateral nodules, supporting simultaneous VATS resection. [ABSTRACT FROM AUTHOR]

Objectives: Evidence-based studies optimizing chest tube management have been conducted to accelerate the recovery process for lung cancer patients after video-assisted thoracoscopic surgery (VATS). This study is to evaluate whether using the multi-lateral pores chest tube can achieve better drainage performance than conventional-lateral-pore drainage. Methods: Data from patients undergoing VATS were consecutively collected from September 2023 to June 2024. The groups were randomized into two subgroups, which were multi-lateral-pores drainage group (MDG) and conventional-lateral-pore drainage group (CDG). The primary outcomes included chest drainage performance, and the secondary outcomes included postoperative complications (PPCs). Results: After screening, 228 patients were randomized into two groups, in which 116 patients in MDG and 112 patients in CDG. The daily drainage volume [199.70 (95%CI: 165.19~234.99) mL/d vs 149.43 (95%CI: 120.70~179.21) mL/d, P<0.01] and total drainage volume [342.79 (95%CI: 291.91~392.63) mL vs 272.68 (95%CI: 225.87~322.11) mL, P = 0.04] in the MDG was significantly higher that that in the CDG. The drainage duration in the MDG was also less than that in the CDG [36.41 (95%CI: 32.23~40.72) h vs 51.02 (95%CI: 46.03~56.38) h, P < 0.01]. The incidence of pleural effusion was lower in the MDG when compared with that in CDG (1.7% vs 9.0%, P = 0.04). No differences were found in the other incidences of chest tube—related PPCs, including pneumothorax (12.0% vs 15.2%, P = 0.15) and subcutaneous emphysema (17.2% vs 17.9%, P = 0.35), however. Conclusions: Based on this single-center analysis, multi-lateral pores chest tube provided better drainage performance after VATS. [ABSTRACT FROM AUTHOR]

Purpose: This study was conducted to evaluate the postoperative short-term outcomes of patients undergoing video-assisted thoracoscopic surgery (VATS) for lung resection with the enhanced recovery after surgery (ERAS) protocol. Methods: A single-institution, prospective randomized controlled study was conducted. The primary outcome measures were postoperative pulmonary complications (PPCs) and postoperative short-term effects. Results: Among the 611 patients, 305 were assigned to the ERAS group, and 306 were assigned to the routine group. The ERAS group achieved earlier oral feeding, earlier mobilization, a shorter duration of drainage (2.0 vs. 5.0 days, P<0.001), and a shorter hospital stay (3.0 vs. 7.0 days, P<0.001). The biological impacts were confirmed to be significantly better for the ERAS group. Furthermore, the ERAS group also had a lower incidence of PPCs (11.5% vs. 22.9%, P<0.001) than did the routine group. Multivariate logistic regression analysis revealed the following predictors of drainage tube removal on the 1st day after surgery without pneumonia during hospitalization: comorbidity (P=0.029), surgical procedure (P=0.001), and operation time (P=0.039). Conclusions: Implementation of the ERAS protocol led to a decreased incidence of PPCs, suggesting that the ERAS protocol has a better biological impact on patients undergoing VATS for lung resection. Multigradient individual ERAS protocols are recommended at different institutions according to the individual conditions of patients.

Background: Robot-assisted thoracoscopic surgery (RATS) thymectomy has been increasingly performed for treating thymic epithelial tumors in recent years. However, there are very limited reports on the long-term oncologic outcomes after RATS thymectomy, particularly in comparison to Video-assisted thoracoscopic surgery (VATS). This study aimed to compare the perioperative and long-term oncological outcomes between RATS and VATS. Methods: The study was conducted on 180 consecutive patients undergoing RATS or VATS between July 2016 and December 2019, 85 of whom underwent RATS, and 95 of whom underwent VATS. A 1:1 matched propensity score-matched analysis was performed and the perioperative and long-term oncologic outcomes of the two groups compared. Result: RATS group experienced a shorter operation time (median: 100 min vs. 120 min; P = 0.039) and less blood loss (40.00 ml vs. 50.00 ml, P = 0.011). RATS demonstrated a significantly lower conversion rate to open surgery compared to VATS, with only two patients requiring conversion in the RATS group as opposed to ten patients in the VATS group (3.03% vs. 15.15%, P = 0.030). In the RATS group, the 5-year progression-free survival rate was 87.70%, and the 5-year tumor-related survival rate was 92.31%, demonstrating no statistically significant difference compared to those in the VATS group. Conclusion: Compared with VATS, robotic thymectomy demonstrated excellent perioperative outcomes, and RATS achieved long-term oncologic outcomes comparable to those of VATS. RATS thymectomy could be considered as an effective alternative approach for treating thymic epithelial tumors. [ABSTRACT FROM AUTHOR]

Background: Rib fractures are common in trauma patients, often leading to complications such as pneumonia and prolonged hospitalization. Surgical Stabilization of Rib Fractures (SSRF) has become increasingly prevalent in treating severe cases. However, traditional approaches, like posterolateral thoracotomy, are invasive and cause significant muscle damage. Recently, muscle-sparing minimally invasive techniques have been introduced, yet they still require advanced reduction and fixation techniques to avoid complications. This study presents an "ultra" minimally invasive SSRF (uMI-SSRF) technique designed to minimize surgical wounds and soft tissue damage while maintaining the benefits of rib fixation. Methods: This study involved 76 patients with multiple rib fractures treated using the uMI-SSRF technique between August 2021 and December 2023. Preoperative chest tomography with 3D reconstruction was used for surgical planning. The technique employed small incisions (3–5 cm), muscle-sparing approaches, and advanced fixation techniques. Data on patient demographics, intraoperative details, and postoperative outcomes were collected. Results: The mean patient age was 58 years, with 66% being male. On average, patients had 6.4 fractured ribs, and 3.5 ribs with 3.88 plates were fixed per surgery, achieving a fixation/fracture ratio of 59%. The average wound length was 4.2 cm, with a mean operation time of 122 min. Most patients required only one incision (74%). The median hospital length of stay was 7 days, with a pneumonia rate of 5%. No wound infections or implant-related complications were observed. Conclusions: The uMI-SSRF technique effectively reduces wound size and soft tissue damage in rib fracture stabilization while maintaining high fixation quality. This method shows promise for improving patient outcomes, reducing recovery time, and minimizing complications. Further studies with larger sample sizes and comparisons with other methods are warranted to verify the advantages of uMI-SSRF. [ABSTRACT FROM AUTHOR]

Objective: To systematically evaluate the risk factors of conversion to thoracotomy in thoracoscopic surgery (VATS) for lung cancer, and to provide a theoretical basis for the development of personalized surgical plans. Methods: CNKI, Wanfang, VIP, CBM, PubMed, Cochrane Library, Web of Science, and Embase databases were searched by computer from the establishment of the database to March 2024. Relevant studies on the risk factors of conversion to thoracotomy in VATS for lung cancer were searched. Two reviewers independently performed literature screening, data extraction, and quality evaluation, and Stata16.0 software was used for data analysis. Results: A total of 14 studies were included in this study, with a total sample size of 10605, and a total of 11 risk factors were obtained. Mate analysis showed that, Age ≥ 65 years old [OR(95%CI) = 2.61(1.67,4.09)], male [OR(95%CI) = 1.46(1.19,1.79)], BMI(Body Mass Index) ≥ 25 [OR(95%CI) = 1.79(1.17,2.74)], tuberculosis history [OR(95%CI) = 7.67(4.25,13.83)], enlarged mediastinal lymph nodes [OR(95%CI) = 2.33(1.50,3.06)], lung door swollen lymph nodes [OR(95%CI) = 6.33(2.07,19.32)], pleural adhesion [OR(95%CI) = 2.50(1.93,3.25)], tumor located in the lung Upper lobe [OR(95%CI) = 4.01(2.87,5.60)], sleeve lobectomy [OR(95%CI) = 3.40(1.43,8.08)], diameter of tumor ≥ 3.5cm [OR(95%CI) = 2.13(1.15,3.95)] associated with lung cancer VATS transit thoracotomy. Conclusions: Age ≥ 65 years old, male, BMI ≥ 25, tuberculosis history, enlarged mediastinal lymph nodes, lung door swollen lymph nodes, pleural adhesion, tumor located in the lung Upper lobe, sleeve lobectomy, diameter of tumor ≥ 3.5cm are risk factors for conversion to thoracotomy during VATS for lung cancer. Clinicians should pay attention to the above factors before VATS to avoid forced conversion due to the above factors during VATS. Due to the number and limitations of the included studies, the above conclusions need to be validated by additional high-quality studies. Trail registration: The protocol was registered into the PROSPERO database under the number CRD42023478648. [ABSTRACT FROM AUTHOR]

Background: This study seeks to investigate the contemporary use and effectiveness of fibrinolysis as a first-line option in pediatric empyema. Methods: The Pediatric Health Information System (PHIS) was queried to identify patients with empyema without fistula (2018–2023). First-line treatments were chest drainage (CD), chest drainage with fibrinolysis (CDF), and video-assisted thoracoscopic surgery/open decortication (VATS/OD). Outcomes between groups were compared using Kruskal–Wallis and Chi-Square tests. Multivariate generalized linear model was used to account for covariates. Results: 581 individuals/cases met inclusion criteria. CD accounted for 11.9% of cases, CDF for 67.6%, and VATS/OD for 20.7%. After adjusting for covariates differences in LOS were not significant (p = 0.393). Subsequent VATS/ODs were required in 6.9% of CDF cases, 8.9% of CD, and 3.3% of primary VATS/OD. Additionally, 32.5% of primary VATS/OD received adjuvant fibrinolysis. Complications were more often observed in the VATS/OD group compared to CD and CDF (11.7% vs 5.8% and 4.1% respectively; p =.008). There were no differences in 30-day readmission rate (VATS/OD:1.2%, CTD:1.5%, and CTDF:1%; p = 0.83). Conclusion: Fibrinolysis is now utilized as first-line treatment for most patients and as adjunct in other approaches. The findings justify further implementation as it is the less invasive first-line primary therapy in patients with empyema. [ABSTRACT FROM AUTHOR]

AbstractBackgroundMethodsResultsConclusionWhen chest tube drainage does not adequately resolve thoracic empyema, video assisted thoracoscopic surgery (VATS) is often needed. However, the proper duration of antibiotics after VATS is poorly defined. Consequently, the objective of this study was to evaluate if short antibiotic durations post-VATS was equally effective compared to longer durations.Patients with thoracic empyema treated with VATS were identified retrospectively by a query of the hospital billing database. The bacterial causes of the empyema were divided into 8 different categories while the antibiotic duration after VATS was divided into two groups which included antibiotics ˂ 14 days and antibiotics >14 days. The primary outcome measured was rates of empyema recurrence. Statistical comparisons were conducted between the antibiotic duration groups overall and when stratified based on the different bacterial causes.137 patients were included in this study with the main cause of empyema being culture negative empyema (37.2%) while alpha haemolytic Streptococcus spp. was the most cultured bacteria (26.3%). There was no statistical difference (p = 0.5168), in the rates of empyema recurrence, when short antibiotic durations (median 11.6 days)were compared to longer antibiotic durations (median 29.1 days)post-VATS. Nor was there a statistical difference in recurrence rates when stratifying based on bacterial cause.This study reinforces that antibiotic durations less than 14 days post-VATS are equally effective as prolonged antibiotic durations. However, to determine the proper duration of antibiotic therapy post-VATS, a prospective clinical trial is needed to reduce complications of prolonged antibiotic therapies for these patients.

OBJECTIVES Minimally invasive anatomic segmentectomy for the resection of pulmonary nodules has significantly increased in the last few years. Nevertheless, there is limited evidence on the safety and feasibility of robotic segmentectomy compared to video-assisted thoracic surgery. This study aimed to compare the real-world early outcomes of robotic and video-thoracoscopic surgery in anatomic segmentectomy. METHODS Single-centre cohort study including all consecutive patients undergoing segmentectomy by either robotic or video-thoracoscopic from June 2018 to November 2023. Propensity score case matching analysis generated 2 matched groups undergoing robotic or video-thoracoscopic segmentectomy. Short-term outcomes were analysed and compared between groups. RESULTS 204 patients (75 robotic and 129 video-thoracoscopic patients) were included. After matching, 146 patients (73 cases in each group) were compared. One 30-day death was observed in the robotic group (P  = 1). Two conversions to thoracotomy occurred in the robotic, and none in the video-thoracoscopic group (P  = 0.5). Surgical time was longer in the robotic group (P  = 0.091). There were no significant differences between robotic and video-thoracoscopic groups in postoperative complications (13.7% vs 15.1%, P  = 1), cardiopulmonary complications (6.8% vs 6.8%, P  = 1), major complications (4.1% vs 4.1%, P  = 1), prolonged air leak (4.1% vs 5.5%, P  = 1), arrhythmia (1.4% vs 0%, P  = 1) and reoperation (2.7% vs 2.7%, P  = 1). Median length of stay was 3 days (interquartile range 2–3 days) in the robotic group vs 3 days (interquartile range 2.5–4 days) in the video-thoracoscopic group (P  = 0.212). CONCLUSIONS Robotic segmentectomy is a safe and feasible alternative to video-thoracoscopy, as no significant differences in early postoperative outcomes were found between the 2 techniques.

An ectopic thyroid (ET) involves numerous scenarios of detection and outcomes, while its current management is not standardised. A mediastinal ET (MET) represents a low index of suspicion. In this paper, we introduce a 47-year-old female who was accidentally identified with an MET, and a modern surgical approach was provided. An anterior mediastinal mass of 3.2 cm was found at CT upon a prior COVID-19 infection. Previous to the infection, she experienced non-specific complaints for a few months (intermittent night sweats, facial erythema, chest pressure, and dyspnoea). Also, CT identified a thymus-like mass and a left adrenal incidentaloma of 3 cm. The endocrine panel was normal, and the subject declined further investigations. She was re-admitted 12 months later: the MET had increased +1 cm (+45% volume) and was confirmed at a 99mTc pertechnetate scintigraphy. Noting the symptoms, mediastinal anatomy, and size change, the MET was removed via a minimally invasive trans-cervical approach (eutopic gland preservation) with the help of a Cooper thymectomy retractor (which also allowed for a synchronous thymus mass resection). No post-operatory complications were registered, the thyroid function remained normal, and the mentioned symptoms were remitted. A histological exam confirmed a benign MET and thymus hyperplasia, respectively. To conclude, this case pinpoints important aspects, such as the clinical picture became clear only upon thoracic surgery due to the complete remission of the complaints that initially seemed widely non-specific. The incidental MET finding was associated with a second (adrenal) incidentaloma, a scenario that might not be so rare, following multiple imaging scans amid the COVID-19 era (no common pathogenic traits have been identified so far). The co-presence of a thymus mass represented one more argument for surgery. Minimally invasive cervicotomy associated with eutopic gland conservation and the use of a Cooper thymectomy retractor highlight modern aspects in video-assisted thoracic surgery, which provided an excellent outcome, involving one of the lowest mediastinal thyroids to be removed by this specific procedure. Awareness of such unusual entities helps inform individualised, multidisciplinary decisions for optimum prognoses. [ABSTRACT FROM AUTHOR]

Background/Objectives: Endometriosis is characterized by the presence of ectopic endometrial-like glands and stroma outside the endometrial cavity, which mainly occurs in the pelvic cavity. Pulmonary endometriosis, or thoracic endometriosis syndrome (TES), describes the rare presence of endometrial-like cells in the thoracic cavity and includes catamenial pneumothorax, catamenial hemothorax, hemoptysis, and lung nodules. Our aim is to summarize the results of all reported cases of TES. Methods: Extensive research was conducted through MEDLINE/PUBMED using the keywords "thoracic endometriosis", "thoracic endometriosis syndrome", "catamenial pneumothorax", "catamenial hemoptysis", and "TES". Following PRISMA guidelines, all published cases of TES between January 1950 and March 2024 were included. A systematic review of 202 studies in English, including 592 patients, was performed. Results: The median age of women with TES is 33.8 years old. The most common clinical presentation is catamenial pneumothorax (68.4%), while lesions are mainly found in the right lung unilaterally (79.9%). Chest computed tomography (CT) was used alone or after an X-ray to determine the pathological findings. Ground-glass opacity nodules and cystic lesions represent the most common finding in CT, while pneumothorax is the most common finding in X-rays. Video-assisted thoracoscopic surgery (VATS) is the main therapeutic approach, usually in combination with hormonal therapy, including GnRH analogues, progestins, androgens, or combined oral contraceptives. Hormonal therapy was also administered as monotherapy. Symptom recurrence was reported in 10.1% of all cases after the treatment. Conclusions: High clinical awareness and a multidisciplinary approach are necessary for the best clinical outcome for TES patients. More studies are required to extract safer conclusions.

BACKGROUND: Traumatic hemothorax (HTX) is often managed with tube thoracostomy (TT); however, TT carries a high complication rate. In 2017, a guideline was implemented at our Level I trauma center to observe traumatic HTX 300 mL or less in patients who are hemodynamically stable. We hypothesized that this guideline would decrease TT placement without increasing observation failure rates. STUDY DESIGN: This was a single-center retrospective review of all adult patients admitted with an HTX on CT before (2015 to 2016) and after (2018 to 2019) the guideline implementation. Exclusion criteria were TT placement before CT scan, absence of CT scan, death within 5 days of admission, and a concurrent pneumothorax more than 20 mm. HTX volume was calculated using CT scan images and Mergo's formula: V = d2 x L (where V is the volume, d is the depth, and L is the length). The primary outcome was observation failure, defined as the need for TT, video-assisted thoracoscopic surgery, thoracotomy after repeat imaging or worsening of symptoms, and pulmonary morbidity. RESULTS: A total of 357 patients met inclusion criteria, of whom 210 were admitted after guideline implementation. No significant differences in baseline demographics, comorbidities, or injury characteristics across both cohorts were observed. The postimplementation cohort had a significant increase in observation rate (75% vs 59%) and a decrease in TT placement (42% vs 57%). The postimplementation group had a statistically significant shorter hospital (6 vs 8 days) and ICU (2 vs 3 days) length of stay. No significant differences in observation failure, pulmonary complications, 30-day readmission, or 30-day mortality were observed across both cohorts. CONCLUSIONS: The implementation of the 300-mL guideline led to a decrease in TT placement without increasing observation failure or complication rates. [ABSTRACT FROM AUTHOR]

Background: With growing concerns about opioid-related risks, efforts to reduce opioid use throughout the perioperative period have increased. This study aimed to compare postoperative recovery outcomes between opioid-free anesthesia (OFA) and opioid-sparing anesthesia (OSA) under a multimodal analgesic protocol in video-assisted thoracoscopic surgery (VATS). Methods: A retrospective cohort study was conducted on 196 patients undergoing VATS from August 2019 to December 2021. Patients received either dexmedetomidine-based OFA or remifentanil-based OSA. Postoperative recovery was assessed using the Quality of Recovery-15 (QoR-15) score, opioid consumption, and pain intensity. Additionally, opioid-related complications and intraoperative hemodynamic changes were evaluated. Results: Both groups showed similar QoR-15 scores 24 h postoperatively (124.2 ± 7.0 vs. 123.0 ± 6.9, p = 0.227). Opioid consumption and pain intensity were comparable, and the incidence of opioid-related adverse events did not significantly differ between the groups. Intraoperative hypotension and bradycardia were more frequent in the OFA group, but the differences were not statistically significant. Conclusions: The study concluded that both OFA and OSA, when used under a multimodal analgesic protocol, provided effective postoperative recovery in patients undergoing VATS with no significant differences in outcomes.

Objectives: The choice of the best Video-Assisted Thoracic Surgery (VATS) surgical approach is still debated. Surgeons are often faced with the choice between innovation and self-confidence. The present study reports the experience of a high-volume single institute, comparing data of uni-portal, bi-portal and tri-portal VATS, to find out the safest and most effective mini-invasive approach, leading surgeon's choice. Methods: Between 2015 and 2022, a total of 210 matched patients underwent VATS lobectomy for early-stage cancer, using uni-portal (fifth intercostal space), bi-portal (seventh space for optic and the fifth), and tri-portal (seventh and the fifth/four) access. Patients were matched for age, BPCO, smoke, comorbidities, lesions (size and staging) to obtain three homogenous groups (A: uni-portal; B: bi-portal; C: tri-portal). The surgeons had comparable expertise. Data were retrospectively collected from institutional database and analyzed. Results: No differences were detected considering time of surgery, length of hospital stay, complications, conversion rate, specific survival, and days of chest tube length of stay. Better results on chest tube removal were described in group A (mean 1.1 days) compared to B (mean 2.6 days) and C (mean 4.7 days); nevertheless, they not statistically significant (p = 0.106). Conclusions: No significant differences among the groups were described, except for the reduction in chest tube permanence in group A. This allows to hypothesize an enhanced recovery after surgery in this group but the different approaches in this series seem to guarantee comparable safety and effectiveness. Considering no superiority of one method above the others, the best suggested approach should be the one for which the surgeon feels more confident. [ABSTRACT FROM AUTHOR]

Vaping-associated spontaneous pneumothorax (VASP) is a new diagnosis created to describe spontaneous pneumothorax associated with the use of vape devices. We describe a case of bilateral VASP in a previously healthy 15-yearold male who was vaping cannabis concentrate. This is the first case report of VASP involving the sole usage of cannabis concentrate. This patient reported vaping for only 6 months before initial presentation. As rates of vaping cannabis concentrate increase among adolescents, VASP should be considered in the differential diagnosis of chest pain in adolescents who vape nicotine or cannabis.

Introduction: Currently, there is little evidence on the surgical management of pulmonary complications of COVID-19 pneumonia. This study aimed to give insight into common complications arising in patients with COVID-19 pneumonia that require lung resections. Methods: This is a retrospective single-center study looking at conditions arising in patients with COVID-19 pneumonia who required lung resection for resolution between March 2020 and March 2021. Clinical presentation, indications to undergo surgery, and factors associated with increased mortality were analyzed. Analysis of nominal variables was performed using nonparametric statistical tests. Results: Twelve men (92.3%) and one woman (7.7%) were included in the analysis; the age of included participants ranged from 27 to 72 years, with the mean age being 52. The most common presenting signs and symptoms were dyspnea and tachypnea, which were present in all patients, most common cause for surgery was pneumatocele with 6 cases, followed by lung abscess; patients who underwent surgery because of persistent air leak were more likely to require surgical reintervention (p = 0.005). The overall mortality in our sample was 23%. Increasing age (p = 0.014), myalgias (p = 0.035), elevated D-dimer (p = 0.007), and pulmonary embolism (p = 0.014) were associated with increased mortality. Conclusions: Lung resections to treat pulmonary complications in patients with COVID-19 pneumonia appear to be safe, with a survival rate of 77%. Recognizing clinical characteristics such as age, myalgias, elevated D-dimer and pulmonary embolism can aid in identifying those at increased risk. [ABSTRACT FROM AUTHOR]

Background: For patients receiving one lung ventilation in thoracic surgery, numerous studies have proved the superiority of lung protective ventilation of low tidal volume combined with recruitment maneuvers (RM) and individualized PEEP. However, RM may lead to overinflation which aggravates lung injury and intrapulmonary shunt. According to CT results, atelectasis usually forms in gravity dependent lung regions, regardless of body position. So, during anesthesia induction in supine position, atelectasis usually forms in the dorsal parts of lungs, however, when patients are turned into lateral decubitus position, collapsed lung tissue in the dorsal parts would reexpand, while atelectasis would slowly reappear in the lower flank of the lung. We hypothesize that applying sufficient PEEP without RM before the formation of atelectasis in the lower flank of the lung may beas effective to prevent atelectasis and thus improve oxygenation as applying PEEP with RM. Methods: A total of 84 patients scheduled for elective pulmonary lobe resection necessitating one lung ventilation will be recruited and randomized totwo parallel groups. For all patients, one lung ventilation is initiated the right after patients are turned into lateral decubitus position. For patients in the study group, individualized PEEP titration is started the moment one lung ventilation is started, while patients in the control group will receive a recruitment maneuver followed by individualized PEEP titration after initiation of one lung ventilation. The primary endpoint will be oxygenation index measured at T4. Secondary endpoints will include intrapulmonary shunt, respiratory mechanics, PPCs, and hemodynamic indicators. Discussion: Numerous previous studies compared the effects of individualized PEEP applied alone with that applied in combination with RM on oxygenation index, PPCs, intrapulmonary shunt and respiratory mechanics after atelectasis was formed in patients receiving one lung ventilation during thoracoscopic surgery. In this study, we will apply individualized PEEP before the formation of atelectasis while not performing RM in patients allocated to the study group, and then we're going to observe its effects on the aspects mentioned above. The results of this trial will provide a ventilation strategy that may be conductive to improving intraoperative oxygenation and avoiding the detrimental effects of RM for patients receiving one lung ventilation.

Purposes: Robot-assisted thoracoscopic (RATS) segmentectomy is becoming increasingly common because of the expanded indications for segmentectomy and the widespread adoption of robotic surgery. The precise division of the intersegmental plane is necessary to ensure oncologic margins from the tumor and to preserve the lung function. In this study, we present a strategy for accurately dividing the intersegmental plane using a robotic stapler and review the surgical outcomes. Methods: RATS portal segmentectomy was performed using the Da Vinci Xi system and the intersegmental plane was dissected using a robotic stapler. We evaluated the perioperative outcomes in 92 patients who underwent RATS portal segmentectomy between May 2020 and January 2023. These results were compared with those of 82 patients who underwent complete video-assisted thoracoscopic surgery (CVATS) during the same period. Results: The operative and console times were 162 and 97 min, respectively. No intraoperative complications occurred, and postoperative complications were observed in four cases (4.3%). The operative time, blood loss, postoperative complications, and maximum incision size were significantly lower in the RATS group than in the CVATS group. However, RATS requires a significantly higher number of staplers than CVATS. Conclusions: The division of the intersegmental plane using a robotic stapler in RATS portal segmentectomy was, therefore, found to be safe and effective. [ABSTRACT FROM AUTHOR]

Aim: Esophageal atresia (EA) is the most common congenital esophageal malformation. Thoracoscopic repair is gaining popularity, but controversy persists regarding the ideal surgical approach for this challenging anomaly. This study's aim is to analyze outcomes in terms of quality of life (QoL) of children undergoing thoracotomy and thoracoscopy for type III EA repair. Methods: Perinatal characteristics, malformations, surgical procedures, complications, gastrointestinal, and respiratory current symptoms were collected. QoL was investigated through Esophageal-Atresia-QoL (EAQoL) and Pediatric-QoL (PedsQL) 4.0 standardized and validated questionnaires. Statistical Mann–Whitney test with significance level p < 0.05 was carried out. Main results: A total of 32 patients undergoing type III EA primary repair answered the questionnaire, including 17 thoracotomy and 15 thoracoscopy. Median birth weight was not significantly different between two groups (median [2.385; 2.475], p = 0.3529) while gestational age showed statistically difference (median [36; 38], p = 0.0063). Thirty-five associated malformations (15 thoracotomy, 20 thoracoscopy) in 23 patients were observed. Postoperative complications occurred in nine patients in the thoracotomy group (one recurrent fistula, two leakages, six stenosis) and in six patients in the thoracoscopic group (two recurrent fistula, four stenosis). Analyzing EAQoL, we found statistically significant difference in physical health between the two groups (median [83; 96], p = 0.0119), while there was no difference in social relations, eating, and total score (median [100; 100], p = 0.3473) (median [91; 97], p = 0.5749) (median [91; 96], p = 0.1710). Investigating PedsQL, psychosocial health score (median [88; 98], p = 0.0069), and total score (median [91;99], p = 0.0043) were statically significant different between the groups, whereas there was no difference for physical health score (median [91; 100], p = 0.0706). Conclusions: Thoracoscopic EA repair is safe and feasible, allowing patient to have a better QoL in terms of physical and psychosocial health score. [ABSTRACT FROM AUTHOR]

Background: Although the incidence of postoperative atelectasis could be reduced using lung recruitment manoeuvres, it remains high. We hypothesised that intraoperative visual lung recruitment guided by trans-oesophageal lung ultrasound would be more effective than the conventional method for managing postoperative atelectasis. Methods: In this randomised, controlled, prospective study, 84 patients undergoing thoracoscopic lobectomy were recruited from Affiliated Chengdu Fifth People's Hospital (teaching hospital) in China. Patients were grouped into trans-oesophageal lung ultrasound-guided (Group G, n = 42) and control (Group C, n = 42) groups. Methods: Lung recruitment was performed after anaesthesia induction, before chest closure and before the endotracheal tube extubation. In Group C, recruitment pressure was controlled at 30 cm H2O for 10 s (performed thrice); in Group G, the pressure was controlled at 30 cm H2O (performed thrice), and the tidal volume did not exceed 20 ml kg−1 until no atelectasis was detected by trans-oesophageal ultrasound. The primary outcome was lung ultrasound scores measured at the post anaesthesia care unit 30 min after extubation. The secondary outcomes included the oxygenation index (30 min after extubation) and the incidence of atelectasis (30 min after extubation and 3 days after surgery). Results: The final analysis included 79 patients. The lung ultrasound score was significantly higher in the control group than in the ultrasound-guided group 30 min after extubation (Group C vs. Group G, 8.6 ± 2.6 vs. 6.5 ± 2.0, P < 0.001). No significant difference in the oxygenation indexes 30 min after extubation was observed between the groups (P = 0.074); however, the incidence of atelectasis 30 min after extubation significantly differed between the two groups (Group C vs. Group G, 57% vs. 33%, P = 0.031). The incidence of atelectasis 3 days after surgery did not significantly differ between the two groups (Group C vs. Group G, 45% vs. 28%, P = 0.122). Conclusions: Lung recruitment guided by trans-oesophageal lung ultrasound can reduce lung ultrasound scores and the incidence of atelectasis at the post anaesthesia care unit 30 min after extubation. However, it does not significantly reduce the incidence of atelectasis 3 days after surgery. Trial registration: Registration number: ChiCTR2200062509. Registered on 10 /8/ 2022.

Background: Video-assisted thoracoscopic surgery (VATS) is considered useful for the treatment of parapneumonic empyema in children. However, thoracoscopic management of empyema due to esophageal leakage as an operative complication has not been well described in the literature. Case presentation: We successfully decorticated severe empyema using uniport VATS in 2 children (a 2-year-old boy who suffered esophageal perforation after laparoscopic anti-reflux surgery, and a 7-month-old girl who had anastomotic leakage after thoracoscopic repair of esophageal atresia). In these patients, we noticed that pleural effusion rapidly progressed to empyema and caused respiratory insufficiency due to wide-range coverage by fibrotic pleural rind that was successfully decorticated under video-assisted vision from a mini-thoracotomy, followed by spontaneous healing of the leakage. Conclusions: We did not attempt to closely approach or try to repair the esophageal leakage. We believe that this is an important tip for these situations. [ABSTRACT FROM AUTHOR]

Background: Due to advances in video-assisted thoracic surgery (VATS), the majority of lung resections can be performed safely via VATS with low morbidity and mortality. However, pulmonary artery (PA) bleeding often requires emergency conversion to thoracotomy, potentially leading to a life-threatening situation. We report a case of pulmonary artery injury caused by an unexpected stapler-tissue interaction during uniportal VATS lobectomy, highlighting the importance of recognizing and managing such rare complications to improve patient outcomes. Case presentation: A 63-year-old man underwent uniportal VATS left upper lobectomy for a suspected primary lung cancer. During the procedure, unexpected bleeding occurred from the third branch of the pulmonary artery (A3) after withdrawal of an unfired stapler. The protruding staple of the A3 stump was inadvertently hooked and stretched by the groove of the staple anvil. Although the bleeding was controlled by compression with the lung, the injured A3 stump required repair. Due to the extensive intimal injury near the central part of the left main pulmonary artery and the potential risk of fatal postoperative complications, we converted to open thoracotomy for definitive vascular repair by suturing. The patient had no postoperative complications and was discharged on postoperative day 8. Conclusions: This case report provides valuable lessons regarding the rare stapler-related vascular injury during uniportal VATS lobectomy. It is important to note that even during non-vascular dissection, unexpected stapler-tissue interactions can lead to bleeding. To prevent the vessel stump entanglement with stapler components, maintaining separation between the stapler and staple stumps is crucial. In uniportal VATS, manipulation during stapler insertion is one of the most challenging phases for instrument interference, requiring increased caution to prevent complications such as the vascular injury described in this case. Thorough preoperative planning, specific intraoperative precautions, and adapted safety protocols that address the limitations of uniportal VATS are essential for effective management of potential complications. Although techniques for thoracoscopic vascular control exist, they are not always feasible and conversion to open thoracotomy should be considered when necessary to ensure patient safety.

Background: Thymoma is a primary tumor of the thymus, commonly located in the anterior mediastinum. Most thymomas are benign or low‐grade malignant, but they can invade surrounding organs or metastasize. The primary treatment for thymoma is surgical resection. Traditional methods involve open thoracotomy, but it is traumatic, with slow recovery and many complications. In recent years, with the development of thoracoscopic techniques, thoracoscopic total thymectomy has gradually become the preferred method for small size thymomas due to its minimally invasive, safe, and effective. Methods: This paper introduces a thoracoscopic extend thymectomy technique, the subxiphoid video–assisted thoracoscopic extend thymectomy with sternal suspension. This method involves placing hooks at the upper and lower ends of the sternum to suspend the sternum upward, increasing the thoracic cavity space and facilitating thoracoscopic operations. This research reviews the clinical data of 59 patients with early‐stage thymomas treated with this technique at our center since 2020 and analyzes the perioperative therapeutic efficacy and safety. It also compares the outcomes with those of 17 patients who underwent thoracoscopic approaches. Results: The results show that subxiphoid video–assisted thoracoscopic total thymectomy with sternal suspension is an innovative and effective surgical method, achieving the same tumor eradication as other thoracic surgeries. The flexible switching of observation ports provides a more comprehensive surgical field, reduces surgical trauma and complications, and improves the surgical outcomes and quality of life for patients.

Primary hyperparathyroidism (PHPT) due to ectopic parathyroid adenoma is a rare case of hypercalcemia in the pediatric population. Herein, a rare case of PHPT due to ectopic intrathymic parathyroid adenoma was described in an asymptomatic 15-year-old girl who had incidental diagnosis based on laboratory abnormalities but experienced a 3-month postoperative course of persistently elevated parathyroid hormone (PTH) and hypercalcemia following the initial unsuccessful parathyroidectomy operation carried out in a non-parathyroid expert center. The curative surgical treatment was accomplished only after the patientwas reoperated with video-assisted thoracoscopic surgery (VATS) thymectomy by the surgeon experienced in parathyroid surgery with implementation of the combined imaging modalities for accurate localization of ectopic adenoma including 99mTc sestamibi (MIBI) plus neck and thoracic computed tomography (CT) and the appropriate surgical strategies including intraoperative intact PTH monitoring and frozen section diagnosis. Before the reoperation (VATS thymectomy), laboratory findings showed elevated PTH (1,171 ng/L; reference range: 21.80 ng/L-87.5 ng/L) and hypercalcemia (13.4 mg/dL; reference range: 8.4 mg/dL-10.2 mg/dL). The preoperative PTH levels were 94 ng/L at 5 min after thymectomy and 78 ng/L at 10 min. The PTH and calcium levels were 54.3 ng/L and 8.47 mg/dL, respectively, on postoperative day 1 and were 34.2 ng/L and 8.1 mg/dL on postoperative day 2. The patient was discharged on postoperative day 2 without any complications. In conclusion, our findings indicate the likelihood of isolated primary hyperparathyroidism to be incidentally diagnosed based solely on laboratory abnormalities with no specific clinical manifestations in the pediatric age. In addition, using combined imaging modalities (such as MIBI and CT) in accurate localization of ectopic parathyroid adenoma and implementation of surgery by experienced surgeons along with intraoperative intact PTH monitoring and frozen section diagnosis seem crucial to ensure the curative surgical treatment.

Background: Video-assisted thoracic surgery decortication for phase 3 thoracic empyema is widely accepted, but its optimal timing has not been established. We aim to investigate and assess this timing, in terms of overall survival, for chronic empyema. Methods: Two hundred four patients with pneumonia-caused phase 3 empyema were treated with video-assisted thoracic surgery decortication over 10-years at Changhua Christian Hospital. The 90-day post-operative survival status was analyzed, and we compared the survivor group versus the non-survivor group. A receiver operating characteristic curve was used to identify the optimal decortication timing. Results: A comparison between survivors and non-survivors showed statistical differences among age (p=0.004), presence of cardiovascular disease (p=0.018), presence of end-stage renal disease (p=0.002), duration to surgery (p=0.013), length of intensive care unit stay (p=0.010), and overall length of hospital stay (p=0.015). ROC curve analysis determined the cut-off for video-assisted thoracic surgery decortication, based on optimal 90-day post-operative survival, to be 7.5 days after hospitalization; mortality increases threefold thereafter (14.2% vs 44.6%, p<0.001). Multivariate analysis revealed that age, end-stage renal disease, pleural effusion pH≦7.2 and duration to surgery >7.5 days negatively impacted 90-day post-operative survival. Conclusions: Patients receiving decortication surgery within 7.5 days of hospital admission had better overall survival. [ABSTRACT FROM AUTHOR]

Background: Rib fractures are one of the most common traumatic injuries and may result in significant morbidity and mortality. Despite growing evidence, technological advances and increasing acceptance, surgical stabilization of rib fractures (SSRF) remains not uniformly considered in trauma centers. Indications, contraindications, appropriate timing, surgical approaches and utilized implants are part of an ongoing debate. The present position paper, which is endorsed by the World Society of Emergency Surgery (WSES), and supported by the Chest Wall Injury Society, aims to provide a review of the literature investigating the use of SSRF in rib fracture management to develop graded position statements, providing an updated guide and reference for SSRF. Methods: This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of experts then critically revised the manuscript and discussed it in detail, to develop a consensus on the position statements. Results: A total of 287 studies (systematic reviews, randomized clinical trial, prospective and retrospective comparative studies, case series, original articles) have been selected from an initial pool of 9928 studies. Thirty-nine graded position statements were put forward to address eight crucial aspects of SSRF: surgical indications, contraindications, optimal timing of surgery, preoperative imaging evaluation, rib fracture sites for surgical fixation, management of concurrent thoracic injuries, surgical approach, stabilization methods and material selection. Conclusion: This consensus document addresses the key focus questions on surgical treatment of rib fractures. The expert recommendations clarify current evidences on SSRF indications, timing, operative planning, approaches and techniques, with the aim to guide clinicians in optimizing the management of rib fractures, to improve patient outcomes and direct future research.

Background: One-lung ventilation and intrathoracic operations during thoracoscopic surgery often result in intraoperative hypoxaemia and haemodynamic fluctuations, resulting in perioperative myocardial injury. Dexmedetomidine, an alpha-2 (α-2) agonist, has demonstrated myocardial protection. We hypothesize that the routine intravenous administration of dexmedetomidine could reduce the extent of myocardial injury during video-assisted thoracoscopic surgery (VATS). Methods: The study included patients aged ≥ 45 years, classified as American Society of Anesthesiologists physical status I-III, who underwent general anesthesia for video-assisted thoracoscopic surgery. The patients were randomly assigned to either the intervention group, receiving general anesthesia with dexmedetomidine, or the control group, receiving general anesthesia without dexmedetomidine. Patients in the intervention group received a loading dose of dexmedetomidine (0.5 µg·kg−1) before anesthesia induction, followed by a continuous infusion (0.5 µg·kg−1·h−1) until the completion of the surgery. Placebos (saline) were administered for the control group to match the treatment. The primary outcome assessed was the high-sensitivity cardiac troponin T on postoperative day 1. Additionally, the incidence of myocardial injury after noncardiac surgery (MINS) was noted. Results: A total of 110 participants completed this study. The median [interquartile range (IQR)] concentration of hs-cTnT on postoperative day 1 was lower in the intervention group compared with the control group (7 [6-9] vs. 8 [7-11] pg·ml−1; difference in medians,1 pg·ml−1; 95% confidence interval [CI], 0 to 2; P = 0.005). Similarly, on postoperative day 3, the median [IQR] concentration of hs-cTnT in the intervention group was also lower than that in the control group (6 [5-7] vs. 7 [6-9]; difference in medians,1 pg·ml−1; 95%CI, 0 to 2; P = 0.011). Although the incidence of MINS was not statistically significant (the intervention group vs. the control group, 3.8% vs. 9.1%, P = 0.465), there was a decreasing trend in the incidence of MINS in the intervention group. Conclusion: The administration of perioperative dexmedetomidine in patients ≥ 45 years undergoing video-assisted thoracoscopic surgery could lower the release of postoperative hs-cTnT without reducing incidence of myocardial injury.

Background: Postoperative pain is a prevalent symptom experienced by patients undergoing surgical procedures. This study aims to develop deep learning algorithms for predicting acute postoperative pain using both essential patient details and real-time vital sign data during surgery. Methods: Through a retrospective observational approach, we utilized Graph Attention Networks (GAT) and graph Transformer Networks (GTN) deep learning algorithms to construct the DoseFormer model while incorporating an attention mechanism. This model employed patient information and intraoperative vital signs obtained during Video-assisted thoracoscopic surgery (VATS) surgery to anticipate postoperative pain. By categorizing the static and dynamic data, the DoseFormer model performed binary classification to predict the likelihood of postoperative acute pain. Results: A total of 1758 patients were initially included, with 1552 patients after data cleaning. These patients were then divided into training set (n = 931) and testing set (n = 621). In the testing set, the DoseFormer model exhibited significantly higher AUROC (0.98) compared to classical machine learning algorithms. Furthermore, the DoseFormer model displayed a significantly higher F1 value (0.85) in comparison to other classical machine learning algorithms. Notably, the attending anesthesiologists' F1 values (attending: 0.49, fellow: 0.43, Resident: 0.16) were significantly lower than those of the DoseFormer model in predicting acute postoperative pain. Conclusions: Deep learning model can predict postoperative acute pain events based on patients' basic information and intraoperative vital signs. [ABSTRACT FROM AUTHOR]

Background: Both microcoils and hook-wires are commonly utilized for preoperative pulmonary nodule localization due to their convenience, but it remains unclear which one should be prioritized for recommendation. Aims: To compare the safety and efficacy of microcoils and hook-wires for pulmonary nodule localization. Methods: From January 2021 to December 2021, 310 consecutive patients (113 males and 197 females) with 341 pulmonary nodules who underwent CT-guided microcoil or hook-wire localization prior to video-assisted thoracoscopic surgery (VATS) at our center were retrospectively included in this study. There were 161 patients in the microcoil group and 149 patients in the hook-wire group. The successful localization rate, complication rate, radiation exposure, and medical costs were compared between the two groups. Results: A total of 341 pulmonary nodules were localized, with a success rate of 99% (180/184) in the microcoil group and 93% (146/157) in the hook-wire group, respectively. All patients successfully underwent VATS. Multivariate analysis revealed that hook-wire localization, shorter needle depth into the lung tissue and the longer waiting time from localization to VATS were the risk factors for the localization failure. The incidences of pneumothorax in the microcoil group and hook-wire group were 34.8% (56/161) and 34.9% (52/149), respectively (P = 0.983). The incidences of pneumorrhagia were 13% (24/184) and 46.5% (73/157), respectively (P = 0.000). Multivariate analysis revealed that hook-wire localization and greater depth of needle penetration into lung tissue were risk factors for pneumorrhagia. Conclusion: Microcoil localization of pulmonary nodules is superior to hook-wire localization in terms of efficacy and safety. This finding provides insight into priority and broader promotion of microcoil localization. Main points: CT-guided localization of pulmonary nodules can improve the success rate of video-assisted thoracoscopic pulmonary wedge resection. CT-guided microcoil or hook-wire localization of pulmonary nodules prior to video-assisted thoracoscopic surgery is a well-established technique with a high success rate and a low incidence of major complications. Due to their material properties, microcoils are more stable than hook-wires in terms of localization, allowing for longer waiting periods for surgery after localization without dislodgment, with a lower risk of pulmonary bleeding, and a better patient experience.

Objective: This study aims to evaluate the real-world effectiveness of applying different levels of Enhanced Recovery After Surgery (ERAS) guidelines to video-assisted thoracic day surgery (VATS). The goal is to determine the optimal degree of ERAS protocols and management requirements to improve postoperative recovery outcomes. Methods: It was designed as a single-centre, prospective pragmatic randomized controlled trial (PRCT), including patients who underwent VATS at the Day Surgery Center of West China Hospital, between January 2021 and November 2022. Patients were divided into Group A and Group B through convenience sampling to implement different levels of ERAS management protocols. Data collection included the baseline characteristics (gender, age, marital status, education level, BMI, PONV risk score, ASA classification), surgery-related indicators (type of surgery, pathological results, hospitalization costs, duration of surgery, intraoperative blood loss, intraoperative rehydration volume), postoperative recovery indicators (postoperative chest tube duration time, time to first postoperative ambulation and urination, postoperative complications, follow-up condition), pain-related indicators (pain threshold score, pain score at 6 h postoperatively, bedtime, and predischarge), psychological state indicators (anxiety level), Athens Insomnia Scale (AIS) scores, and social support scores. Propensity score matching (PSM) was utilized and statistical analyses were conducted using R version 4.4.1. Comparisons of categorical variables were performed using the χ² test, while comparisons of continuous variables were conducted using ANOVA or the Kruskal-Wallis rank-sum test. A significance level of α = 0.05 was set for statistical tests. Result: A total of 340 patients were included, with 187 in Group A and 153 in Group B. After propensity score matching (PSM), there were 142 patients in Group A and 105 in Group B, with no significant baseline differences. Group A had a significantly higher proportion of chest tube removals within 24 h postoperatively (P < 0.001) and earlier mobilization (P < 0.001). Despite a higher pain threshold in Group A (P = 0.016), their postoperative pain scores were not higher than those in Group B. Additionally, Group A had a lower incidence of postoperative complications. Conclusion: The more comprehensive ERAS protocol significantly improved postoperative recovery, confirming its value in day-case VATS and supporting its clinical adoption. However, the study has limitations; future research should focus on standardizing ERAS protocols and expanding their application to a broader patient population to validate these findings further. Trail Registration: This study underwent review by the Ethics Committee of West China Hospital of Sichuan University under No. 2020 (1001). It has been officially registered with the China Clinical Trial Registry, TRN: ChiCTR2100051372 and registration date is Sept. 22, 2021. [ABSTRACT FROM AUTHOR]

Background: Before thoracoscopic surgery, diagnosing tuberculous (TB) pleurisy was a medical challenge. Thoracoscopy is the most accurate but expensive method for TB pleurisy diagnosis. TB is common in low-income countries, where financial limitations prevent the use of thoracoscopy, motivating the search for a cheaper alternative. Patients and methods: A prospective study was done from January 2019 to January 2023 to evaluate diagnostic methods for patients with exudative pleural effusions (PE) of unknown etiologies. The demographic, radiological, procedural, and histological data of exudative PE patients were analyzed. All patients were examined for adenosine deaminase (ADA) and lymphocyte/neutrophil ratio in pleural fluid. Ultrasound-guided Abrams needle biopsy and video-assisted thoracoscopic surgery pleural biopsies were obtained, and histopathological results were assessed. Results: Of 250 patients with PE, 161 (64%) had TB PE, 72 (28.8%) had malignant PE, and 17 (6.8%) had idiopathic PE. Sensitivity of ADA (≥40 U/l) was 88%, lymphocyte/neutrophil ratio (≥0.75) was 86.1%, and their overall sensitivity was 91%. They had 93.2, 86.3, and 100% specificity, respectively. For ultrasound-guided Abrams needle biopsy, the sensitivity of histopathology, culture, and combined histopathology/culture was 66, 46.5, and 78.4%, respectively. All were 100% specific. For thoracoscopic biopsy, the sensitivity of histopathology, culture, and combined histopathology/culture was 100, 86.6, and 100%, respectively. All were 100% specific. The assay sensitivity of pleural fluid and tissue Xpert Mycobacterium tuberculosis /rifampin resistance was 12.5 and 49.7%, respectively. Both were 100% specific. Combining ADA more than or equal to 40 U/l, lymphocyte/neutrophil ratio more than or equal to 0.75, and an ultrasound-guided Abrams needle biopsy yielded 92.4% sensitivity and 100% specificity. Conclusion: Combining pleural fluid ADA more than or equal to 40 U/l, lymphocyte/neutrophil ratio more than or equal to 0.75, and ultrasound-guided Abrams needle biopsy can accurately detect TB PE in high-TB populations. It may be an affordable alternative to thoracoscopy in countries with limited resources. [ABSTRACT FROM AUTHOR]

AIMS: Primary spontaneous pneumothorax (PSP) is a sudden pleural disease predominantly affecting healthy adolescents and young adults, making it a prevalent thoracic disorder within this demographic. This study evaluated the necessity of preoperative chest tube insertion for PSP patients and reassessed current clinical practices. METHODS: We conducted a retrospective analysis of medical records for individuals aged 14–30 years diagnosed with PSP who underwent video-assisted thoracoscopic surgery (VATS) at Wonju Severance Christian Hospital from January 2016 to December 2022. Patients were categorized retrospectively into two groups based on their initial treatment: Those who had a chest tube inserted and those who did not. We collected and compared clinical data, including demographics, treatment specifics, and outcomes. RESULTS: The study included 128 PSP cases. There was no difference in preoperative clinical data between the two groups, and there were no differences in operation time, number of wedge resections, and number of mechanical pleurodesis. However, the use of single-port surgery was significantly higher in the nonchest tube group (P = 0.001). The nonchest tube group had a significantly shorter hospital stay (P < 0.001), attributed to the absence of preoperative chest tube insertions. There were no significant differences in postoperative complications or recurrence rates between the groups. CONCLUSIONS: In young PSP patients, proceeding directly to VATS without prior chest tube insertion in stable individuals does not lead to serious complications or negatively affect outcomes. This approach may offer an effective alternative for PSP management. [ABSTRACT FROM AUTHOR]

Chylothorax is a rare condition in which chylous fluid accumulates in the pleural cavity, most often due to iatrogenic injury of the thoracic duct. This paper reports a case of a woman in her 50s presenting with chyle leakage after a video-assisted mediastinoscopic lymphadenectomy (VAMLA) for staging of a nodule suspected of non-small cell lung carcinoma. After the VAMLA, a Uniportal Video Assisted Thoracoscopic Surgery lobectomy was scheduled during which the chylothorax was observed. The chyle was evacuated and the planned resection was conducted. The chest drain could be removed after 6 days while the patient followed a medium-chain triglyceride diet for 4 weeks. The purpose of this case report is to raise awareness for this very rare complication after VAMLA and discuss treatment options. [ABSTRACT FROM AUTHOR]

Bronchogenic cysts, a rare congenital pulmonary disorder, typically affect young adults and are often managed conservatively. However, large cysts with recurrent infections require surgical intervention. This case study highlights the successful management of a large bronchogenic cyst. A 53-year-old female presented with a decade-long history of recurrent respiratory infections manifesting as cough, yellow purulent sputum, and shortness of breath. Chest computed tomography revealed a large bronchogenic cyst in the right middle lobe, causing cardiac compression. Despite conservative management, the recurrent symptoms persisted. After multidisciplinary consultation, a thoracoscopic right middle lobectomy was planned. Severe pleural adhesions and bleeding complicated the procedure; therefore, thoracotomy was performed. Postoperatively, the patient developed transient fever and elevated white blood cell count, both of which resolved with appropriate antibiotic therapy. The patient was discharged in stable condition, with no recurrence of symptoms at follow-up. Large, symptomatic bronchogenic cysts that cause recurrent infections require surgical resection.

OBJECTIVES This single-centre prospective observational study aimed to investigate reasons for prolonged hospitalization [over the median length of stay (LOS)] after enhanced recovery thoracoscopic [ERAS 3-port video-assisted thoracoscopic surgery (VATS)] wedge resection. METHODS All patients were evaluated twice-daily by an investigator for reasons of hospitalization. Each reason was analysed individually. Predictors for prolonged hospitalization were identified using a multivariable backward stepwise logistic regression model. RESULTS A total of 150 consecutive patients (lymphadenectomy 8.7%) were included from November 2022 to December 2023, with a median LOS of 1 (interquartile range 1–2) day. Of these, 55 patients (36.7%) experienced prolonged hospitalization. The main reasons included postoperative pain (16.0%), air leak (14.7%) and social factors (14.7%), followed by oxygen dependency (7.3%), gastrointestinal factors (5.3%), urinary factors (4.7%), pneumonia (1.3%), pleural effusion (1.3%), chylothorax (0.7%), atrial fibrillation (0.7%), confusion (0.7%) and fatigue (0.7%). Multivariable analysis revealed that an increase in the percentage of predicted forced expiratory volume in 1 s (FEV1%pre) by 1% [odds ratio (OR) 0.41, P = 0.023) and percentage of predicted diffusing capacity for carbon monoxide (DLCO%pre) by 1% (OR 0.95, P = 0.002) decreased likelihood of prolonged hospitalization. Conversely, each additional pack-year (OR 1.01, P = 0.028) and living alone (OR 3.55, P = 0.005) increased the risk of prolonged hospitalization. CONCLUSIONS Prolonged hospitalization (LOS > 1 day) after ERAS 3-port VATS wedge resection, with 8.7% lymphadenectomy, was mainly due to pain, air leak and social factors. Smokers with decreased FEV1%pre or DLCO%pre and patient living alone were at increased risk.

OBJECTIVES CALGB140503/JCOG0802 RCTs comparing lobectomy with sublobar resection in stage IA NSCLC have confirmed the non-inferiority of segmentectomy. Additional insight is needed to improve preoperative work-up and intraoperative strategies to increase safety and promote the dissemination of minimally invasive segmentectomy (MIS). A Delphi panel study assessed the level of consensus among surgeons for the planning and management of MIS. METHODS Twenty-one expert lung surgeons represented academic institutions, major teaching hospitals, and community hospitals from Europe, North America, and Asia. A 3-round Delphi methodology was used to analyse the answers of each panellist. Recognizing that questions with fewer response options have a higher consensus probability due to limited variability, weighted consensus thresholds were modified based on the number of response options. RESULTS The 21 panellists responded to all 3 rounds of questions. Based on the most robust consensus (94.4%), 3D chest CT reconstructions are recommended only when planning complex segmentectomies. Surgeons should perform 3D reconstructions chest CT scans (consensus = 83.3%). The most effective and safest technique is image-guided VATS in a hybrid operating room (consensus = 83.3%). Dyes with intravenous administration are the safest technique for identifying the intersegmental plane during MIS (consensus = 72.2%). Augmented/mixed reality will probably not immediately help reduce perioperative complications (consensus = 72.2%). CONCLUSIONS This Delphi consensus supports 3D reconstructions and preoperative pulmonary nodule localization before complex MIS. These recommendations should be considered when allocating resources to improve MIS's safety and oncologic efficacy for patients with small, early-stage lung cancers. [ABSTRACT FROM AUTHOR]

OBJECTIVES Minimally invasive thymectomy is an accepted approach for early-stage thymic epithelial neoplasia, reducing pain and length of stay compared with open surgery. In this study, we compare robotic and video-assisted thymectomy to assess pathological resection status, overall and disease-free survival. METHODS Data were retrieved from the European Society of Thoracic Surgeons prospectively maintained thymic database. Eighty-two international centres were invited to participate in the ESTS registry. Thirty-seven centres agreed to take part. We included all patients who had undergone complete thymectomy for malignancy through a minimally invasive approach and excluded patients in whom complete data were not available. RESULTS Between October 2001 and May 2021, a total of 899 patients with thymic malignancy underwent minimal access surgical resection and were included in the study. A propensity matched analysis was conducted with interrogation of 732 patients. Median age was 55 years, and 408 (56%) patients were female. Propensity matched was performed with 1:1 matching for surgical approach (video assisted = 366, robot assisted = 366). Robot-assisted surgery conferred significantly lower odds of incomplete resection (R1; 0.203 95% CI 0.13–0.317; P  < 0.001). However, there was no difference in terms of overall and disease-free survival between the 2 techniques. CONCLUSIONS In this analysis, after adjusting for thymoma stage, the odds of incomplete surgical resection were higher in patients undergoing video-assisted surgery than robotic. However, there was no difference in overall or disease-free survival. With data maturation and increased follow-up, this would need repeat analysis and perhaps may provide more credence to the concept of a prospective randomized study to compare outcomes in thymic epithelial neoplasia by surgical approach with a standardized pathological work-up.

OBJECTIVES Postoperative pain remains a burden for patients after minimally invasive anatomic lung resection. Current guidelines recommend the intraoperative placement of intercostal catheters to promote faster recovery. This trial aimed to determine the analgesic efficacy of continuous loco-regional ropivacaine application via intercostal catheter and establish this method as a possible standard of care. METHODS Between December 2021 and October 2023, patients were randomly assigned to receive ropivacaine 0.2% or a placebo through an intercostal catheter with a flow rate of 6–8 ml/h for 72 h after surgery. Patients were undergoing anatomic VATS lung resection under general anaesthesia for confirmed or suspected stage I lung cancer (UICC, 8th edition). The sample size was calculated to assess a difference in numerical rating scale associated with pain reduction of 1.5 points. RESULTS Fourteen patients were included in the ropivacaine group, whereas the placebo group comprised 18 participants. Patient characteristics and preoperative pain scores were similar in both groups. There was no statistically significant difference in postoperative pain scores and morphine consumption between the 2 groups. The mean numerical rating scale when coughing during the first 24 h postoperatively was 4.9 (SD: 2.2) in the ropivacaine group and 4.3 (SD: 2.4); P  = 0.47 in the placebo group. We were unable to determine any effect of administered ropivacaine on the postoperative pulmonary function (FEV1, PEF). CONCLUSIONS Our preliminary results suggest that continuous loco-regional ropivacaine administration via surgically placed intercostal catheter has no positive effect on postoperative pain scores or morphine requirements.

Pulmonary sequestration (PS) is a rare congenital pulmonary dysplasia. The most important feature is vascularisation with Pulmonary sequestration (PS) is a rare form of congenital pulmonary dysplasia, with the most significant feature being vascularization with atypical arteries, generally originating in the thoracic and abdominal aorta. There are two forms of PS, interlobar (ILS) and extralobar (ELS), which are distinguishable based on their relationship with the visceral pleura. Surgical resection and ligation of the feeding vessels are the standard treatments for the condition. In the present study, two cases with different sequestration types are presented along with a review of the treatment options. [ABSTRACT FROM AUTHOR]
