Study designRetrospective cohort study of prospectively accrued data.ObjectiveTo evaluate a large, prospective, multicentre dataset of surgically treated degenerative cervical myelopathy (DCM) cases on the contemporary risk of C5 palsy with surgical approach.Summary of background dataThe influence of surgical technique on postoperative C5 palsy after decompression for DCM is intensely debated. Comprehensive, covariate-adjusted analyses are needed using contemporary data.MethodsPatients with moderate to severe DCM were prospectively enrolled in the multicenter, randomized, Phase III CSM-Protect clinical trial and underwent either anterior or posterior decompression between Jan 31, 2012 and May 16, 2017. The primary outcome was the incidence of postoperative C5 palsy, defined as the onset of muscle weakness by at least one grade in manual muscle test at the C5 myotome with slight or absent sensory disruption after cervical surgery. Two comparative cohorts were made based on the anterior or posterior surgical approach. Multivariate hierarchical mixed-effects logistic regression was used to estimate odds ratios (OR) with 95% confidence intervals (CI) for C5 palsy.ResultsA total of 283 patients were included, and 53.4% underwent posterior decompression. The total incidence of postoperative C5 palsy was 7.4% and was significantly higher in patients who underwent posterior decompression compared with anterior decompression (11.26% vs. 3.03%, P =0.008). After multivariable regression, the posterior approach was independently associated with greater than four times the likelihood of postoperative C5 palsy ( P =0.017). Rates of C5 palsy recovery were comparable between the two surgical approaches.ConclusionThe odds of postoperative C5 palsy are significantly higher after posterior decompression compared to anterior decompression for DCM. This may influence surgical decision-making when there is equipoise in deciding between anterior and posterior treatment options for DCM.Level of evidenceTherapeutic Level-II.

BACKGROUND: Endoscopic spine surgery has recently grown in popularity due to the potential benefits of reduced pain and faster recovery time as compared to open surgery. Biportal spinal endoscopy has been successfully applied to lumbar disc herniations and lumbar spinal stenosis. Obesity is associated with increased risk of complications in spine surgery. Few prior studies have investigated the impact of obesity and associated medical comorbidities with biportal spinal endoscopy. METHODS: This study was a prospectively collected, retrospectively analyzed comparative cohort design. Patients were divided into cohorts of normal body weight (Bone Mass Index (BMI)18.0-24.9), overweight (BMI 25.0-29.9) and obese (BMI > 30.0) as defined by the World Health Organization (WHO). Patients underwent biportal spinal endoscopy by a single surgeon at a single institution for treatment of lumbar disc herniations and lumbar spinal stenosis. Demographic data, surgical complications, and patient-reported outcomes were analyzed. Statistics were calculated amongst treatment groups using analysis of variance and chi square where appropriate. Statistical significance was determined as p

ObjectiveThoracic outlet syndrome (TOS) has life-changing impacts on young athletes. As the level of competition increases between the high school (HS) and collegiate (CO) stage of athletics, the impact of TOS may differ. Our objective is to compare surgical outcomes of TOS in HS and CO athletes.MethodsThis was a retrospective review of HS and CO athletes within a prospective surgical TOS database. The primary outcome was postoperative return to sport. Secondary outcomes were resolution of symptoms assessed with somatic pain scale (SPS), QuickDASH, and Derkash scores. Categorical and continuous variables were compared using χ2 and analysis of variance, respectively. Significance was defined as P < .05.ResultsThirty-two HS and 52 CO athletes were identified. Females comprised 82.9% HS and 61.5% CO athletes (P = .08). Primary diagnoses were similar between groups (venous TOS: HS 50.0% vs CO 42.3%; neurogenic TOS: 43.9% vs 57.7%; pectoralis minor syndrome: 6.3% vs 0.0%) (P = .12). Pectoralis minor syndrome was a secondary diagnosis in 3.1% and 3.8% of HS and CO athletes, respectively (P = 1.00). The most common sports were those with overhead motion, specifically baseball/softball (39.3%), volleyball (12.4%), and water polo (10.1%), and did not differ between groups (P = .145). Distribution of TOS operations were similar in HS and CO (First rib resection: 94.3% vs 98.1%; scalenectomy: 0.0% vs 1.9%, pectoralis minor tenotomy: 6.3% vs 0.0%) (P = .15). Operating room time was 90.0 vs 105.3 minutes for HS and CO athletes, respectively (P = .14). Mean length of stay was 2.0 vs 1.9 days for HS and CO athletes (P = .91). Mean follow-up was 6.9 months for HS athletes and 10.5 months for CO athletes (P = .39). The majority of patients experienced symptom resolution (HS 80.0% vs CO 77.8%; P = 1.00), as well as improvement in SPS, QuickDASH, and Derkash scores. Return to sport was similar between HS and CO athletes (72.4% vs 73.3%; P = .93). Medical disability was reported in 100% HS athletes and 58.3% CO athletes who did not return to sport (P = .035).ConclusionsDespite increased level of competition, HS and CO athletes demonstrate similar rates of symptom resolution and return to competition. Of those that did not return to their sport, HS athletes reported higher rates of medical disability as a reason for not returning to sport compared with CO athletes.

Despite the known higher risk of cardiovascular disease in individuals with type 2 diabetes, the pathophysiology and optimal management of diabetic foot ulcers (DFUs), a leading complication associated with diabetes, is complex and continues to evolve. Complications of type 2 diabetes, such as DFUs, are a major cause of morbidity and mortality and the leading cause of major lower extremity amputation in the United States. There has recently been a strong focus on the prevention and early treatment of DFUs, leading to the development of multidisciplinary diabetic wound and amputation prevention clinics across the country. Mounting evidence has shown that, despite these efforts, amputations associated with DFUs continue to increase. Furthermore, due to increasing patient complexity of management secondary to comorbid conditions, such as cardiovascular disease, the management of peripheral artery disease associated with DFUs has become increasingly difficult, and care delivery is often episodic and fragmented. Although structured, process-specific approaches exist at individual institutions for the management of DFUs in the cardiovascular patient population, there is insufficient awareness of these principles in the general medicine communities. Furthermore, there is growing interest in better understanding the mechanistic underpinnings of DFUs to better define personalized medicine to improve outcomes. The goals of this scientific statement are to provide salient background information on the complex pathogenesis and current management of DFUs in cardiovascular patients, to guide therapeutic and preventive strategies and future research directions, and to inform public policy makers on health disparities and other barriers to improving and advancing care in this expanding patient population.

INTRODUCTION: As surgical technologies grow, so too do demands on surgical trainees to master increasing numbers of skill sets. With the rise of endovascular surgery, trainees have fewer opportunities to practice open vascular techniques in the operating room. Simulation can bridge this gap. However, existing published open vascular simulation curricula are basic or based on expensive models. METHODS: We iteratively developed an open vascular skills curriculum for second-year surgery residents comprising six 2-hour sessions. We refined the curriculum based on feedback from learners and faculty. The curriculum required skilled facilitators, vascular instruments, and tissue models. We evaluated the latest iteration with a survey and by assessing participants technical skills using the Objective Structured Assessment of Technical Skills (OSATS) form. RESULTS: Over the past 10 years, 101 residents have participated in the curriculum. Nine of 13 residents who participated in the latest curricular iteration completed the survey. All respondents rated the sessions as excellent and strongly agreed that they had improved their abilities to perform anastomoses with tissue and prosthetic. Facilitators completed 18 OSATS forms for residents in the fifth and sixth sessions of the latest iteration. Residents scored well overall, with a median 26.5 (interquartile range: 24-29) out of a possible score of 35, with highest scores on knowledge of instruments. DISCUSSION: This simulation-based curriculum facilitates open vascular surgical skill acquisition among surgery residents. The curriculum allows residents to acquire critical vascular skills that are challenging to learn in an increasingly demanding operative setting.

INTRODUCTION: The fibrous posterior atlanto-occipital membrane (PAOM) at the craniocervical junction is typically removed during decompression surgery for Chiari malformation type I (CM-I); however, its importance and ultrastructural architecture have not been investigated in children. We hypothesized that there are structural differences in the PAOM of patients with CM-I and those without. METHODS: In this prospective study, blinded pathological analysis was performed on PAOM specimens from children who had surgery for CM-I and children who had surgery for posterior fossa tumors (controls). Clinical and radiographic data were collected. Statistical analysis included comparisons between the CM-I and control cohorts and correlations with imaging measures. RESULTS: A total of 35 children (mean age at surgery 10.7 years; 94.3% white) with viable specimens for evaluation were enrolled: 24 with CM-I and 11 controls. There were no statistical demographic differences between the two cohorts. Four children had a family history of CM-I and five had a syndromic condition. The cohorts had similar measurements of tonsillar descent, syringomyelia, basion to C2, and condylar-to-C2 vertical axis (all p>0.05). The clival-axial angle was lower in patients with CM-I (138.1 vs. 149.3 degrees, p = 0.016). Morphologically, the PAOM demonstrated statistically higher proportions of disorganized architecture in patients with CM-I (75.0% vs. 36.4%, p = 0.012). There were no differences in PAOM fat, elastin, or collagen percentages overall and no differences in imaging or ultrastructural findings between male and female patients. Posterior fossa volume was lower in children with CM-I (163,234 mm3 vs. 218,305 mm3, p

Background: The prevalence of abnormal electrocardiography (ECG) increases with aging, and these abnormalities may have an impact on anesthesia management. Although a normal ECG does not guarantee a healthy heart, an abnormal ECG can quickly identify a patient who is at high risk of cardiac complications. Objective: The aim of this study was to determine the prevalence and associated factors of preoperative abnormal electrocardiography among older surgical patients at selected teaching hospitals in southern Ethiopia, from February 15 to June 15, 2022. Methodology: A multicenter cross-sectional study was conducted at three randomly selected teaching hospitals in southern Ethiopia on 246 elderly surgical patients recruited consecutively. Data were entered into Epidata version 4.6, then exported and analyzed in STATA version 16. A binary logistic regression model was used to examine factors associated with abnormal ECG, and variables with a P-value < 0.2 were entered into the multivariate analysis to identify independent factors. Both crude and adjusted odds ratios were reported, and a P-value < 0.05 was considered statistically significant. The data were presented using frequencies, tables, charts, and figures. Result: In the current study, 120 (48.78%) of older surgical patients had abnormal preoperative ECGs. In terms of severity, 55.3% were classified as minor, while 44.16% were major ECG abnormalities. The most common ECG abnormalities were left axis deviation (LAD), left ventricular hypertrophy (LVH), and ST segment changes. The presence of comorbidity (AOR = 3.44, P = 0.001), age ≥ 70 years (AOR = 2.5, P = 0.011), history of angina (AOR = 5.9, P = 0.011), history of smoking (AOR = 5.07, P = 0.024) and urban residency (AOR = 1.89, P = 0.039) were the strongest risk factors for an abnormal ECG. Conclusion and recommendation: Our study shows that older patients are more likely to have an abnormal ECG before surgery, regardless of symptoms or risk factors. Therefore, it is suggested that all older patients undergo preoperative ECG screening. Further prospective cohort studies are needed to investigate the impact and outcome of patients with preoperative abnormal ECG. [ABSTRACT FROM AUTHOR]

Airway management is a key intervention during the resuscitation of critically ill trauma patients. Emergency surgical airway (ESA) placement is taught as a backup option when endotracheal intubation (ETI) fails. We sought to (1) describe the incidence of the emergency department (ED) ESA, (2) compare ESA versus ETI-only recipients, and (3) determine which factors were associated with receipt of an ESA. We searched within the Trauma Quality Improvement Program datasets from 2017 to 2022 for all emergency department surgical airway placement and/or endotracheal intubations recipients. We compared ESA versus ETI-only recipients. From 2017 to 2022, there were 6,477,759 within the datasets, of which 238,128 met inclusion for this analysis. Within that, there were 236,292 ETIs, 2264 ESAs, with 428 (<1 %) having documentation of both. Of the ESAs performed, there were 82 documented in children <15 years of age with the youngest being 1 year of age. The ETI-only group had a lower proportion serious injuries to the head/neck (52 % versus 59 %), face (2 % versus 8 %), and skin (3 % versus 6 %). However, the ETI-only group had a higher proportion of serious injuries to the abdomen (15 % versus 9 %) and the extremities (19 % versus 12 %). Survival at 24-h was higher in the ETI-only group (83 % versus 76 %) as well as survival to discharge (70 % versus 67 %). In the subanaysis of children <15 years (n = 82), 34 % occurred in the 1–4 years age group, 35 % in the 5–9 years age group, and 30 % in the 10–14 years age group. In our multivariable logistic regression analysis, serious injuries to the head/neck (odds ratio [OR] 1.37, 95 % CI 1.23–1.54), face (OR 3.41, 2.83–4.11), thorax (OR 1.19, 1.06–1.33), and skin (OR 1.53, 1.15–2.05) were all associated with receipt of cricothyrotomy. Firearm (OR 3.62, 3.18–4.12), stabbing (2.85, 2.09–3.89), and other (OR 2.85, 2.09–3.89) were associated with receipt of ESA when using collision as the reference variable. ESA placement is a rarely performed procedure but frequently used as a primary airway intervention in this dataset. Penetrating mechanisms, and injuries to face were most associated with ESA placement. Our findings reinforce the need to maintain this critical airway skill for trauma management. • Emergency surgical airway (ESA) access is often used as a primary airway intervention. • ESA access is documented in children as young as 1 with similar survival to adults. • Serious injuries to the face, firearms, and stabbings are associated with receipt of ESA.

Primary patellar dislocation has a certain recurrence rate after either conservative or surgical treatment, and the optimal treatment for patients with primary patellar dislocation of different ages remains unclear. This study aims to compare the clinical efficacy of surgical and conservative treatments for primary patellar dislocation across different age groups. According to the Preferred Reporting Items for Systematic Reviews and Meta‐analyses (PRISMA) checklist, we conducted a systematic search for randomized controlled trials. We searched the PubMed, EMBASE, Cochrane Library, and Web of Science databases for randomized controlled trials of primary patellar dislocation treated surgically or conservatively up to January 2023. Data searching, extraction, analysis, and quality assessment were carried out in accordance with the Cochrane Collaboration guidelines. A total of nine studies with 433 patients were included in our study. There was no statistically significant difference between the two treatment modalities in terms of Kujala score, pain score, patient satisfaction, reoperation, and Tegner score. The rate of re‐dislocation after surgical treatment is lower than that after conservative treatment. Subgroup analysis based on mean age showed that when the age was >20 years, Kujala scores were higher after surgical treatment than after conservative treatment (p < 0.0001, 95% confidence interval [CI] = 10.41–21.30). When the age was ≤20 years, the difference in Kujala scores between the two treatment modalities was not statistically significant. When the age was >20 years, the recurrence rate of patellar dislocation was lower after surgical treatment than after conservative treatment (p = 0.009, 95% CI = 0.08–0.70). When the age was ≤20 years, the difference in the recurrence rate of patellar dislocation between the two treatment modalities was not statistically significant. When the age of patients with primary patellar dislocation is ≤20 years, both surgical and conservative treatments result in similar clinical outcomes. When the age is >20 years, better clinical outcomes can be achieved by opting for surgical treatment. Therefore, surgery may be a better option for patients with primary patellar dislocation whose age is >20 years. [ABSTRACT FROM AUTHOR]

OBJECTIVES Endoscopic evaluation of anastomosis is effective for the early detection of anastomotic complications after a bronchoplastic procedure. Herein, we aimed to clarify important findings for predicting anastomotic complications. METHODS This single-centre retrospective study included patients who underwent bronchoplastic surgery between April 2013 and September 2023. Only cases in which bronchoscopy was performed both 1 and 2 weeks after surgery were included. Endoscopic findings (classification by Ludwig and Stoelben, mucosa colour, oedema, slough area and colour and depression) were reviewed for all cases. The accuracy of these findings for predicting anastomotic complications was evaluated. RESULTS Of the 190 patients included in this study, 14 (7.4%) experienced anastomotic abnormalities, 11 had fistulas (5.8%) and 7 had stenosis (3.7%). The onsets of fistula and stenosis were 20–28 and 20–44 days after surgery, respectively. In 102 patients (53.7%), the slough worsened from the first to the second week postsurgery. Therefore, it was easier to evaluate slough 2 weeks postsurgery rather than 1-week postsurgery. The positive/negative predicted values of anastomotic complications in endoscopic findings 2 weeks postsurgery were circular slough, 34.2%/99.3%; slough with dark colour, 39.3%/98.1%; and depression, 54.2%/99.4%. The incidence of anastomotic abnormalities was 0% in cases without the 3 findings, 10% in cases with at least 1 finding and 67% in cases with all 3 findings. CONCLUSIONS The endoscopic findings of slough on the anastomosis 2 weeks after bronchoplasty can be easily evaluated and accurately predict complications. Three important endoscopic findings were circular slough, dark colour and depression. [ABSTRACT FROM AUTHOR]

Introduction. Bone metastases occurring distally to the elbow or knee joint are called acrometastases. Acrometastases make up only 0.1% of all bone metastases, but only 0.007% to 0.3% occur in the bones of the foot or hand. In 10% of patients, bone metastases occur as the first sign of a previously undiagnosed primary tumor. Case report. A 64-year-old male reported to the hospital due to painful swelling and redness of the fifth finger of the dominant hand. Osteolysis of the proximal phalanx of the fifth finger was diagnosed radiographically. A working diagnosis of osteomyelitis and phlegmon of the proximal phalanx was made. After incisional drainage, a tumor mass was observed intraoperatively. Amputation of the finger was performed at the level of the metacarpophalangeal joint. Pathohistological analysis revealed squamous cell carcinoma metastasis. After a computed tomography scan and bronchoscopy with biopsy, a diagnosis of squamous cell carcinoma of the bronchus was made. The patient was given chemotherapy. During the application of the second cycle, there was a fatal outcome. Conclusion. Pathohistological verification and determination of the location of the primary tumor are important when acrometastasis is found because starting novel immunotherapy and targeted therapy in a timely manner could change the median survival of these patients.

Bone Anchored Hearing Aids (BAHAs) are currently well-utilized for treatment of hearing-impaired patients with unilateral or bilateral mixed and conductive hearing loss as well as patients with single sided deafness. The objective of this study is to evaluate outcome of BAHA Attract system in terms of surgical, functional,audiological and cosmetic results This is a prospective observational study of 15 consecutive patients of single sided deafness (SSD) who qualified for and underwent BAHA Attract surgery at a tertiary care hospital over a duration of two years. Parameters analysed were: (1) Surgery and wound healing, (2) Post-operative functional results (Bern Benefit for Single sided deafness questionnaire (BBSSQ)), (3) audiological results (free field speech in noise audiometry in two situations: with signal from implanted side and from contralateral side), (4) Cosmetic results (introduction of novel Three Points Scoring System (TPSS). Clinico-radiological planning of surgical site for implant is also described.Mean surgical time was 39 minutes and healing was uneventful in 73 % of patients. All patients reported improvement in all ten hearing situations with maximum improvement for sound localization. Significant improvement of speech in noise was seen especially when signal was presented from implanted side. All patient had full score in TPSS for cosmesis except one patient. This was the same patient in whom clinico-radiologically planned site was discarded intraoperatively due to overpneumatised temporal bone.BAHA Attract system is safeand effective solution for single sided deafness with acceptable cosmesis.

The prognosis in gastrointestinal system malignancies is directly correlated with the stage of the disease at the time of presentation. There are debates and variations in the preferred methods for staging (3,4). Despite being part of the recommendations of international associations in preoperative staging, the adequacy of CT is controversial. In our study, we aimed to investigate the effectiveness of CT in the decision of inoperability based on our case series of patients who were admitted to our clinic with a preliminary diagnosis of gastrointestinal system malignancy and deemed inoperable. At the General Surgery Clinic of - University Training and Research Hospital, demographic data of patients with intraoperatively detected inoperable gastrointestinal malignancies between 2018 and 2023, preoperative CT and endoscopy findings, surgical reports, and neoadjuvant treatment applications were retrospectively analyzed. Preoperative endoscopic and cross-sectional imaging findings were compared with intraoperative findings. The study included 91 patients. The sensitivity of preoperative endoscopy was found to be 80.2%, while the sensitivity of preoperative CT was 69.2%. When comparing organ-based intraoperative findings with the distant invasion signs findings detected in preoperative investigations, no significant difference was found. When the correlation of intraoperative inoperable and widely accepted findings with preoperative treatment was examined, no statistically significant relationship was found in the statistical analysis. In our study, the sensitivity and specificity of CT were found within ranges consistent with the literature. However, the adequacy of CT in invasive and metastatic disease was again found to be low, in line with the literature. Therefore, to prevent misinterpretation, we believe that adding advanced imaging modalities (MRI, PET, EUS) during the preoperative period in addition to CT may help reduce unnecessary laparotomies.

Surgical resection of the stenotic segment with end-to-end anastomosis is considered the gold standard in postintubation tracheal stenosis. However, outcomes of this concrete aetiology are not well described. With the aim to examine the extent, range and characteristics of the existing evidence, a scoping review was performed. Data sources included MEDLINE, Scopus, Ovid and the Cochrane databases. Inclusion criteria consisted of studies in adult patients with postintubation tracheal stenosis that reported characteristics, surgical management and outcomes. A total of 125 articles were identified, of which 10 were included in the final analysis. All studies were case reports or case series (level 4 evidence) grouping 110 patients, 75 males and 35 females. The age ranged from 15 to 71 years. Cotton–Myer stenosis grade was 1 [1 (0.9%)], 2 [25 (22.7%)], 3 [70 (63.6%)] and 4 [14 (12.7%)]. Stenosis location was in the tracheal upper-third in 108 (98.2%), in the middle-third in 1 (0.9%) and in the lower-third in 1 (0.9%). Stenosis length ranged from 1 to 5.6 cm. Follow-up ranged from 1 to 60 months (2 years for the most). Most frequent complications were transitory dysphagia in 13 (11.3%), granuloma formation in 8 (7.3%), dehiscence or air leak in 5 (4.5%) and wound infection in 4 (3.6%). Restenosis rate ranged from 2% to 25%. There was no perioperative mortality. Tracheal resection and primary anastomosis in postintubation tracheal stenosis appear to be safe and effective in the short and mid-terms; however, the very low level of evidence found prevents definitive conclusions.

Background: Virtual reality modeling (VRM) is a 3-dimensional simulation created from patient-specific 2-dimensional (2D) imaging. VRM creates a more accurate representation of the patient anatomy and can improve anatomical perception. We surveyed surgeons on their operative plan in complex pediatric oncology cases based on review of 2D imaging and subsequently after review of VRM. We hypothesized that the confidence level would increase with the use of virtual reality and that VRM may change the operative plan. Methods: Patients were selected and enrolled based on age (<18) and oncological diagnosis. VRM was created based on the 2D imaging. Surgeons identified surgical plans based on 2D imaging and again after VRM. A blinded surgeon not involved with the case also gave opinions on surgical plans after viewing both the 2D and the VRM imaging. These assessments were compared with the actual operation. Results: A total of 12 patients were enrolled. Diagnoses included six neuroblastomas, two Wilms tumors, one Ewing's sarcoma, one pseudopapillary tumor of the pancreas, one rhabdomyosarcoma, and one mediastinal germ cell tumor. VRM increased the operating surgeon's confidence 63% of the time. The operative plan changed 8.3% of the time after VRM. Conclusion: VRM is useful to help clarify operative plans for more complex pediatric cases. [ABSTRACT FROM AUTHOR]

Enucleation is a surgical technique to resect peripheral nerve schwannomas. The procedure has a low risk for postoperative deficit, but a small chance for recurrence, because tumor cells may remain inside the pseudocapsule that is left after resection. Magnetic resonance imaging (MRI) scans are frequently performed after surgery to investigate potential residual tumor, but currently there is little information in the literature on the value of follow-up with MRI. All patients who underwent enucleation of a peripheral nerve schwannoma between October 2013 and June 2022 were included. Postoperative MRI scans (gadolinium-enhanced) made at different time points after the surgery were re-examined for residual enhancement. Patients with residual enhancement were contacted to inform whether symptoms had recurred. A total of 75 schwannoma enucleations in 74 patients were included. The first postoperative MRI scan, performed 3 months after the surgery, showed no residual enhancement in 50 patients. In the remaining 24 patients, another MRI scan was made 1 year after the surgery, which still showed a possible remnant in 11 patients. On the third MRI scan, performed 2 years after enucleation, there were 7 suspected cases (9%). None of these patients had clinical symptoms at a mean postoperative follow-up of 5 years. Our data show that the value of postoperative MRI scans after enucleation of peripheral nerve schwannomas is limited, because residual enhancement in the beginning can be non-specific and the small percentage of patients, that persistently had a potential remnant, were all asymptomatic.

Purpose: To evaluate the mid‐term clinical outcomes for the non‐surgical and surgical management of acute proximal hamstring avulsions. Methods: Sixty physically active individuals were offered surgical or non‐surgical management for their proximal hamstring avulsion injuries. Distal retraction was defined as greater than 2 cm. Primary outcome measures were the Victorian Institute of sport assessment‐proximal hamstring tendons (VISA‐H) and functional assessment scale for acute hamstring injuries (FASH). Secondary outcome measures included palpable gap (cm), return to sport (RTS) and the ability to perform Nordic hamstring curls. Outcome variables were adjusted in regression models for gender, age, and treatment. Results: Thirty‐one patients elected to undertake non‐surgical management, and 29 chose surgery with a mean follow‐up of 34.8 ± 8.7 and 34.9 ± 7.0 months, respectively. The mean VISA‐H for the non‐surgical and surgical groups were 87.3 ± 3.4 and 87.9 ± 4.1 (n.s.), respectively. The mean FASH for the non‐surgical group was 89.3 ± 2.4 and 88 ± 3.6 for the surgical group (n.s.). This was consistent after adjusting for confounders. The mean gap for the non‐surgical group was 4.5 ± 1.09 and 4.9 ± 1.19 cm for the surgical group (n.s.). No significant differences were found in the abilities to perform Nordic hamstring curls (n.s.). Both groups achieved comparable RTS rates (n.s.). On average, the non‐surgical group achieved RTS at 5.5 ± 1.2 months post‐injury, whereas the surgical group was at 5.7 ± 0.7 months (n.s.). Conclusion: Physically active individuals with acute proximal hamstring avulsions and distal retraction of the tendon stump can be managed non‐surgically, achieving similar functional levels and RTS compared to patients treated surgically. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

Mohs Micrographic Surgery (MMS) for treatment of melanoma offers several advantages over wide local excision (WLE), including complete histologic margin evaluation, same-day resection and closure, and sparing of healthy tissue in critical anatomic sites. Recently, a large volume of clinical data demonstrating efficacy in MMS treatment of melanoma was published, leading to emerging patient safety considerations of incurred treatment costs, risk of tumor upstaging, and failure of care coordination for sentinel lymph node biopsy (SLNB). MMS offers a safe, effective, and value-based treatment for both melanoma in situ (MIS) and invasive melanoma (IM), particularly with immunohistochemistry use on frozen sections. Compared to wide local excision, MMS treatment demonstrates similar or improved outcomes for local tumor recurrence, melanoma-specific survival, and overall survival at long-term follow-up. Tumor upstaging risk is low, and if present, alteration to clinical management is minimal. Discussion of SLNB for eligible head and neck IM cases should be done prior to MMS. Though challenging, successful multidisciplinary coordination of SLNB with MMS has been demonstrated. Herein, we provide a detailed clinical review of evidence for MMS treatment of cutaneous melanoma and offer recommendations to address current controversies surrounding the evolving paradigm of surgical management for both MIS and invasive melanoma (IM).

Aims: The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups. Methods: A prospectively registered (ISRCTN95922938) randomized parallel group trial will be conducted. Elderly patients meeting the inclusion criteria with a dorsally displaced distal radius facture will be randomized (1:1 ratio) to either conservative management (cast without further manipulation) or surgery. Patients will be assessed at six, 12, 26 weeks, and 52 weeks post intervention. The primary outcome measure and endpoint will be the Patient-Rated Wrist Evaluation (PRWE) at 52 weeks. In addition, the abbreviated version of the Disabilities of Arm, Shoulder and Hand questionnaire (QuickDASH), EuroQol five-dimension questionnaire, pain score (visual analogue scale 1 to 10), complications, grip strength (dynamometer), range of motion (goniometer), and radiological assessments will be undertaken. A cost-utility analysis will be performed to assess the cost-effectiveness of surgery. We aim to recruit 89 subjects per arm (total sample size 178). Discussion: The results of this study will help guide treatment of dorsally displaced distal radial fractures in the elderly and assess whether surgery offers functional benefit to patients. This is an important finding, as the number of elderly distal radial fractures is estimated to increase in the future due to the ageing population. Evidence-based management strategies are therefore required to ensure the best outcome for the patient and to optimize the use of increasingly scarce healthcare resources.

Abstract Preventive treatments for unruptured intracranial aneurysms (UIAs) are used worldwide. However, the long-term effects to cognition have been underestimated. Using representative sample data from the National Health Insurance Service-Senior Cohort database, we compared cumulative risk of incident dementia between two groups: (1) treatment versus observation group, and (2) within the treatment group (surgical versus endovascular treatment). Cox proportional hazard ratios were estimated after applying one-to-one propensity score matching. Subgroup analyses were conducted to investigate interactions between treatment effects and sex, age and history of stroke, respectively. After matching, 3,763 participants were included in each group. The 10-year incidence rates of dementia were 9.82 and 8.68 per 1,000 person-years in the treatment and observation groups, respectively (HR: 1.11, 95% CI: 0.90–1.38, P = 0.33). Furthermore, the risk of incident dementia was not different between the surgical and endovascular treatment groups (HR: 0.98, 95% CI: 0.70–1.37, P = 0.91). In the subgroup analysis, surgical treatment was associated with an increased risk of developing dementia, particularly among male patient (HR: 2.34, 95% CI: 1.04–5.28). Preventive treatment of UIAs appears acceptable in terms of long-term effects to cognition. However, further researches are strongly required to identify the high risk patients of development of dementia.

IntroductionRigid proctosigmoidoscopy (RP) and flexible sigmoidoscopy (FS) are two modalities commonly used for intraoperative evaluation of colorectal anastomoses. This study seeks to determine whether there is an association between the endoscopic modality used to evaluate colorectal anastomoses and the rate of anastomotic leak (AL), organ space infection, and overall infectious complication.MethodsThe 2012-2018 American College of Surgeons National Surgical Quality Improvement Program database was queried for patients undergoing colorectal anastomoses. Anastomotic evaluation method (RP versus FS) was identified by Current Procedural Terminologycoding and used for group classification. Outcomes measured included AL, organ space infections, and overall infection. Multivariable logistic regression analysis for predicting AL was performed.ResultsWe identified 7100 patients who underwent a colorectal anastomosis with intraoperative endoscopic evaluation. RP was utilized in 3397 (47.8%) and FS in 3703 (52.2%) patients. RP was used more commonly in diverticulitis (44.5% versus 36.2%, P

BACKGROUND: Traditionally, arteriovenous fistulas (AVF) involving the basilic vein (BV) have been created in 1 or 2 stages to allow time for the vein to enlarge before superficialization for potential better fistula maturation. Previous single institution studies and meta-analyses have found conflicting outcomes between single-stage and 2-stage procedures. Our study aims to use a large national database to assess the difference in outcomes between single-stage and 2-stage procedures for dialysis access. METHODS: We studied all patients undergoing BV AVF creation in the Vascular Quality Initiative (VQI) from 2011 to 2021. Patients were split into single-stage or a planned 2-stage procedure for dialysis access. Primary outcomes included dialysis use with index fistula, maturity rate, and number of days from surgery to fistula use. Secondary outcomes included patency (defined by physical exam or imaging on follow-up), 30-day mortality, and postoperative complications (bleeding, steal syndrome, thrombosis, or neuropathy). Logistic regression models were used to assess the association between staged dialysis access procedures and primary outcomes of interest. RESULTS: The cohort consisted of 22,910 individuals of which 7,077 (30.9%) had a 2-staged dialysis access procedure and 15,833 (69.1%) had a single-staged procedure. Average follow-up was 345 days in the single stage and 420 days for 2-stage. Baseline characteristics were significantly different between the 2 groups in terms of medical comorbidities. Primary outcomes were significant for more patients in the 2-stage group undergoing dialysis with the index fistula compared to single stage (31.5% vs. 22.2%, P

Abstract Background Excessive intraoperative bleeding remains a challenge in limb surgeries. The exsanguination tourniquet ring has emerged as a potential solution for effective exsanguination and hemostasis. This study aims to evaluate its efficacy and safety compared to the conventional exsanguination and hemostasis approach (pneumatic tourniquet combined with Esmarch bandage). Methods This randomized controlled trial evaluates the exsanguination tourniquet ring’s effectiveness and safety versus the conventional approach in 220 participants undergoing various limb surgeries. Allocation included experimental and control groups, assesses through efficacy (including intraoperative and total blood loss, hemoglobin levels, and exsanguination and hemostasis effectiveness) and safety (adverse event occurrence) indicators. Results The experimental group (n = 110) utilizes the exsanguination tourniquet ring, while the control group (n = 110) employs the conventional approach. As for intraoperative blood loss, the experimental group is non-inferior to the control group (p-value

Introduction: Pain is the most unpleasant subjective feeling comprising of innumerable emotional and psychological components that require medical advice for relief, regardless of the cause. Transversus Abdominis Plane (TAP) block and Erector Spinae Plane (ESP) block are effectively studied blocks that provide adequate pain control. Aim: To compare postoperative analgesic efficacy in pregnant women undergoing caesarean section under spinal anaesthesia with Ultrasound (USG)-guided TAP block and USG-guided ESP block. Materials and Methods: In this institution-based interventional randomised clinical study, two categories comprising 30 subjects in group I with USG-guided bilateral TAP block and group II with USG-guided bilateral ESP block using Ropivacaine were involved. Visual Analogue Scale (VAS) was used to compare analgesic efficacy. Other parameters for analysis included time of first rescue analgesia, total number of administrations of rescue analgesia within 24 hours, together with Adverse Drug Reactions (ADRs). Statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 21.0. Student’s t-test and Chi-square test were used for data analysis. Results: Subjects in group I had a mean age of 24.9±4.66 years while those in group II were 25.5±3.99 years. The VAS score at 24 hours in group I was 7.22±0.89 and in group II was 6.8±0.83, which was statistically significant with a p-value of 0.0241. USG-guided ESP block was superior to USG-guided TAP block, providing analgesia for 24 hours. Following the first dose, there was a significant delay in rescue analgesia and a reduction in the total administration of rescue analgesia within 24 hours. The first rescue analgesia in group I was at 10.66±2.32 hours and in group II was at 16.66±2.53 hours, with a p-value of 0.0001 indicating a statistically significant difference. No ADRs were reported in either group of participants. Conclusion: ESP block provided a prolonged duration of analgesia, as shown by a decrease in the total VAS score. There was also a significant reduction in the total number of administrations of rescue analgesia within 24 hours when compared to TAP block, suggesting that ESP block provides superior analgesia. Hence, for pain relief in postcaesarean section individuals, ESP block can be regarded as a novel potent option.

Background: The discipline of surgery has become an increasingly less attractive medical specialization for medical students in Saudi Arabia. There has been growing worry over the last decade regarding the reduction in the number of medical students who wish to pursue a career in surgery. This trend has been attributed to various factors that include lifestyle, income, and gender. For the new generation, lifestyle issues and family considerations have become increasingly significant. In addition, there are fewer female role models in surgery for the ever-increasing number of female medical students. Therefore, this study aimed to assess the popularity of surgery among the medical students at Jazan University in Saudi Arabia, as well as the factors that influence their decision. Materials and Methods: A cross-sectional observational study was conducted at Jazan University, Saudi Arabia, from November 2021 to March 2022. The study population comprised 407 medical students enrolled in Jazan University. Data were collected using a self-administered online survey, distributed via students’ E-mail addresses, and shared across various social media platforms to ensure maximum participation. The survey was designed to gather comprehensive information on students’ demographics, including age, gender, academic year, and parental background. In addition, Likert scale questions were included to assess students’ opinions on various factors influencing their preference for a surgical career, particularly about their father’s and mother’s profession. Data analysis was done using the Statistical Package for the Social Sciences (SPSS version 23) by IBM Inc. Descriptive statistics were calculated to summarize the demographic characteristics of the participants and the distribution of responses to Likert scale questions. Results: The study’s findings revealed that multiple factors play a significant role in shaping the popularity of surgery among medical students. Notably, personal traits emerged as influential factors affecting students’ decision pursuing a career in surgery. In addition, gender was found to have a pronounced impact, with differences observed in the inclination toward surgery between male and female students. Furthermore, the place of residence was identified as another contributing factor influencing students’ preferences for a surgical career. Conclusions: The popularity of the surgical career in Saudi Arabia depends on the factors that discourage or encourage the students to choose the career. Thus, enhanced student awareness is required to meet the required workforce in surgical specialties.

Abstract Introduction Abdominal trauma in children is a significant health concern that often leads to severe complications and even death. Children experience trauma more frequently than adults, with approximately one in four pediatric patients suffering from serious abdominal injuries. Falls are the leading cause of such trauma among children, which is intriguing considering that most hospital admissions for pediatric abdominal injuries result from blunt force impacts. Method A retrospective cross-sectional analysis of medical records was conducted to examine all patients under the age of 16 who underwent exploratory laparotomy for abdominal trauma between January 1, 2020, and January 1, 2023. The clinical data were gathered using a data extraction sheet from each patient’s medical charts. Information on socio-demographic characteristics, injury mechanisms, clinical conditions at the initial presentation, intraoperative findings and complications, and patient outcomes were collected. Results The study involved a total of 90 patients, consisting of 72 males (80%) and 18 females (20%). The average age of the patients was 10, with a standard deviation of 4.7, ranging from 2 to 16 years. Half of the patients were below the age of 10, accounting for 46 individuals (51%). The causes of the injuries varied among patients below and above the age of 10. However, overall, bullet injuries were the most common cause, accounting for 28 cases (31%), followed by falls in 21 cases (23.3%), horse or donkey kicks in 10 cases (11.1%), stab injuries in 10 cases (11.1%), horn injuries in 7 cases (7.8%), and road traffic accidents in 6 cases (6.7%). Physical assault, blasts, and other types of injuries, such as hen bites and metal rod injuries, were observed in 8 cases (8.9%) of the patients. Fall accidents, horse or donkey kicks, and horn injuries were particularly more common among children below the age of 10, while bullet injuries and stab injuries were most common among those above the age of 10. Conclusion Following abdominal trauma in children, a range of complications may arise, including immediate issues such as infections and hemorrhaging, as well as long-term consequences like impaired organ functionality and psychological distress. In our region, young children are particularly vulnerable to accidents involving falls, kicks from horses or donkeys, and injuries caused by horns. Therefore, it is crucial to educate parents about these hazards. Additionally, providing appropriate guidance on firearm safety is essential for individuals who possess such weapons.

Abstract Purpose To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture. Methods We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS). Results There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P

Abstract Background Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumor, commonly occurring in young adults and typically affecting the mandibular region. We report an exceptionally rare and highly atypical case of AFS in an elderly female patient originating from the maxillary bone. Case presentation A 66-year-old woman was admitted with a two-week history of a lump in her left upper molar. CT scans suggested a cyst in the maxillary bone. An incisional biopsy revealed a spindle cell neoplasm. MRI showed abnormalities in the left maxilla, indicating a possible tumorous lesion. The patient underwent a subtotal maxillectomy, wide tumor excision, intraoral epithelial flap transplantation, and dental extraction. Histology identified atypical tumor cells with visible mitotic figures. Immunohistochemistry showed negative for PCK and CD34 expression, but positive for Vimentin and SMA expression. The Ki-67 proliferation index ranged from 30 to 50%. These findings suggested a potentially malignant soft tissue tumor in the left maxilla, leaning towards a diagnosis of AFS. The patient received postoperative radiotherapy. There was no recurrence during the six-month follow-up. Conclusion Based on repeated pathological evidence, we report a rare case of an elderly female with AFS originating from the maxillary bone. Surgery and postoperative radiotherapy resulted in a favorable outcome.

Introduction: Patients with head and neck cancer often necessitate complex reconstructions, considering both functional and esthetic concerns. Reconstructions are further complicated by previous radiation therapy and patient co-morbidities, which impair wound healing. A recently introduced synthetic hybrid-scale fiber matrix has been shown to provide durable wound coverage and promote tissue healing as an alternative to traditional biologic allogenic and xenogenic skin substitutes. Case Presentation: Thirteen patients were treated at a single academic hospital between December 1, 2021, and May 1, 2023 with the synthetic matrix in head and neck reconstructions. Reconstructions included exposed muscle, scalp wounds, intra-oral defects, and radial forearm free flap donor sites. Wound sizes ranged from 2 × 2 cm to 18 × 10 cm. Serial photographs were taken to evaluate wound healing at 1, 4, 8, 12, and 16 weeks timepoints after application. Outcomes measured at each timepoint included wound size, presence of granulation tissue, and extent of epithelialization. No hematomas or wound complications were encountered. Complete wound healing was noted between 6 and 12 weeks, dependent on wound size. The synthetic matrix significantly promoted wound healing via early granulation tissue formation and epithelialization, or mucosalization, in all head and neck applications. Scar formation and contracture were acceptable in all cases. Conclusion: The use of synthetic hybrid-scale fiber matrix promotes wound healing and avoids patient morbidity associated with traditional allogenic and biogenic treatments, such as split-thickness skin grafts. This synthetic matrix has been demonstrated to be a valuable asset in the head and neck reconstructive armamentarium.

Background: Excessive intraoperative bleeding remains a challenge in limb surgeries. The exsanguination tourniquet ring has emerged as a potential solution for effective exsanguination and hemostasis. This study aims to evaluate its efficacy and safety compared to the conventional exsanguination and hemostasis approach (pneumatic tourniquet combined with Esmarch bandage). Methods: This randomized controlled trial evaluates the exsanguination tourniquet ring's effectiveness and safety versus the conventional approach in 220 participants undergoing various limb surgeries. Allocation included experimental and control groups, assesses through efficacy (including intraoperative and total blood loss, hemoglobin levels, and exsanguination and hemostasis effectiveness) and safety (adverse event occurrence) indicators. Results: The experimental group (n = 110) utilizes the exsanguination tourniquet ring, while the control group (n = 110) employs the conventional approach. As for intraoperative blood loss, the experimental group is non-inferior to the control group (p-value < 0.001). While no significant difference is found in total blood loss (for the full analysis set, p-value = 0.442; for the per protocol set, p-value = 0.976) and differences in postoperative and preoperative hemoglobin levels (for the full analysis set, p-value = 0.502; for the per protocol set, p-value = 0.928). Regarding exsanguination and hemostasis effectiveness, the full analysis set reveals significantly superior ratings in the experimental group compared to the control group (p-value = 0.002 < 0.05), while the per protocol set analysis indicates no significant difference between the groups (p-value = 0.504). As for safety indicators, adverse events related to the device are minimal in two groups, with only one severe event unrelated to the device. Conclusions: The exsanguination tourniquet ring is an effective and safe device for intraoperative blood loss control in various limb surgeries.

Background: Anxiety before surgery is one of the most challenging aspects of preoperative care. Preoperative anxiety has a number of postoperative complications. There are only a few studies that report on preoperative anxiety in surgical patients in Ethiopia, and their prevalence differs from one study to the next. Objective: The aim of this study was to assess the level of preoperative anxiety and associated factors among surgical patients admitted at public hospitals in southern Ethiopia. Methods: From July to August 2022, a facility-based cross-sectional study was conducted among patients admitted to surgical wards at public hospitals. Data collection was conducted using a pretested, structured questionnaire administered by an interviewer. Preoperative anxiety was assessed using the State-Trait Anxiety Inventory scale. The data were coded and entered in Epi Data Version 4.6, then exported to Statistical Package for Social Sciences version 25 for analysis. To describe the study variables, descriptive statistics were used. The associated factors were then identified using bivariate and multivariate logistic regression analyses. Results were declared at a p-value of less than 0.05 based on an adjusted odds ratio with a 95% confidence interval. Result: A total of 220 patients were enrolled, with a 99.5% response rate. The observed preoperative anxiety level was 57.5% (95%CI: 54.63–62.35). High preoperative anxiety was associated with no formal educational status (AOR: 3.75; 95%CI = 1.36, 10.39), fear of death (AOR =2.01; 95%CI = 1.09, 3.73), fear of waking up in middle of surgery (AOR =3.42; 95%CI =1.19, 9.77), fear of postoperative pain (AOR = 2.56; 95%CI = 1.15, 5.74). Conclusion: This study found that five out of ten patients scheduled for surgery in public hospitals had high levels of preoperative anxiety. Anxiety levels were associated with factors such as the educational status of respondents, fear of death, fear of waking up in the middle of surgery, and fear of postoperative pain. Preoperative anxiety assessments should be conducted regularly in each hospital, and appropriate anxiety-reducing methods must be implemented. [ABSTRACT FROM AUTHOR]

Introduction: Pain is the most unpleasant subjective feeling comprising of innumerable emotional and psychological components that require medical advice for relief, regardless of the cause. Transversus Abdominis Plane (TAP) block and Erector Spinae Plane (ESP) block are effectively studied blocks that provide adequate pain control.

Results: Subjects in group I had a mean age of 24.9±4.66 years while those in group II were 25.5±3.99 years. The VAS score at 24 hours in group I was 7.22±0.89 and in group II was 6.8±0.83, which was statistically significant with a p-value of 0.0241. USG-guided ESP block was superior to USG-guided TAP block, providing analgesia for 24 hours. Following the first dose, there was a significant delay in rescue analgesia and a reduction in the total administration of rescue analgesia within 24 hours. The first rescue analgesia in group I was at 10.66±2.32 hours and in group II was at 16.66±2.53 hours, with a p-value of 0.0001 indicating a statistically significant difference. No ADRs were reported in either group of participants. Conclusion: ESP block provided a prolonged duration of analgesia, as shown by a decrease in the total VAS score. There was also a significant reduction in the total number of administrations of rescue analgesia within 24 hours when compared to TAP block, suggesting that ESP block provides superior analgesia. Hence, for pain relief in postcaesarean section individuals, ESP block can be regarded as a novel potent option. [ABSTRACT FROM AUTHOR]

OBJECTIVES The objective of this study was to enhance the efficiency of aortic arch replacement through the development of a novel frozen elephant trunk (FET) prosthesis with an endovascular side branch for left subclavian artery (LSA) connection. After successful pre-clinical testing, the feasibility and safety of implementing this innovative prosthesis in human subjects were investigated. METHODS Between September 2020 and September 2021, 4 patients (mean age 67) with conditions such as penetrating ulcer, non A–non B aortic dissection and chronic arch aneurysm underwent surgery utilizing the customized device. Surgeries were performed under high moderate hypothermia (27°C), employing bilateral selective antegrade cerebral perfusion (SACP) and distal aortic perfusion. Anastomosis of the FET prosthesis with the aortic arch occurred in zone 1, followed by separate reimplantation of the left common carotid artery and the brachiocephalic artery. RESULTS All patients were discharged in good clinical condition. The mean aortic cross-clamp, antegrade selective cerebral perfusion and distal aortic perfusion times were 111, 71 and 31 min, respectively. Endovascular extension of the side branch for the LSA was required in all cases to prevent endoleak formation. One patient received a stent graft extension at the end of the operation, while 2 others underwent the procedure during their hospital stay. One patient was diagnosed with an endoleak at the first follow-up after 3 months, and endoleak sealing was achieved via the brachial artery with an extension stent graft. CONCLUSIONS Preliminary clinical outcomes suggest that the newly designed FET prosthesis shows promise in simplifying total arch replacement. These initial findings provide a foundation for planned clinical studies to further assess the effectiveness of this modified surgical hybrid graft, with particular attention to the length and diameter of the LSA sidearm.

Studies suggest that ambulation after major lower extremity amputation (LEA) is low and mortality after LEA is high. Successful prosthetic fitting after LEA has a significant quality of life benefit; however, it is unclear if there are benefits in post-LEA mortality. Our objective was to examine a contemporary cohort of patients who underwent LEA and determine if there is an association between fitting for a prosthetic and mortality. We reviewed all patients who underwent LEA between 2015 and 2022 at two academic health care systems in a large metropolitan city. The exposure of interest was prosthetic fitting after LEA. The primary outcomes were mortality within 1 and 3 years of follow-up. Ambulation after LEA was defined as being ambulatory with or without an assistive device. Patients with prior LEA were excluded. Extended Cox models with time-dependent exposure were used to evaluate the association between prosthetic fitting and mortality at 1 and 3 years of follow-up. Among 702 patients who underwent LEA, the mean (SD) age was 64.3 (12.6) years and 329 (46.6%) were fitted for prosthetic. The study population was mostly male (n = 488, 69.5%), predominantly non-Hispanic Black (n = 410, 58.4%), and nearly one-fifth were non-ambulatory before LEA (n = 139 [19.8%]). Of note, 14.3% of all subjects who were nonambulatory at some point after LEA, and 28.5% of patients not ambulatory preoperatively were eventually ambulatory after LEA. The rate of death among those fitted for a prosthetic was 12.0/100 person-years at 1 year and 5.8/100 person-years at 3 years of follow-up; among those not fitted for a prosthetic, the rate of death was 55.7/100 person-years and 50.7/100 person-years at 1 and 3 years of follow-up, respectively. After adjusting for several sociodemographic data points, comorbidities, pre- or post- coronavirus disease 2019 pandemic timeframe, and procedural factors, prosthetic fitting is associated with decreased likelihood of mortality within 1 year of follow-up (adjusted hazard ratio, 0.24; 95% confidence interval, 0.14-0.40) as well as within 3 years (adjusted hazard ratio, 0.40; 95% confidence interval, 0.29-0.55). Prosthetic fitting is associated with improved survival, and preoperative functional status does not always predict postoperative functional status. Characterizing patient, surgical, and rehabilitation factors associated with receipt of prosthetic after LEA may improve long-term survival in these patients. Process measures employed by the Department of Veterans Affairs, such as prosthetic department evaluation of all amputees, may represent a best practice. [ABSTRACT FROM AUTHOR]

Lymphedema and specifically cancer-related lymphedema is not the main focus for both patients and physicians dealing with cancer. Its etiology is an unfortunate complication of cancer treatment. Although lymphedema treatments have gained an appreciable consensus, many practitioners have developed and prefer their own specific protocols and this is especially true for conventional (manual) versus surgical treatments. This collection of presentations explores the incidence and genetics of cancer-related lymphedema, early detection and monitoring techniques, both conventional and operative treatment options, and the importance and role of exercise for patients with cancer-related lymphedema. These assembled presentations provide valuable insights into the challenges and opportunities presented by cancer-related lymphedema including the latest research, treatments, and exercises available to improve patient outcomes and quality of life.

Purpose: To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture. Methods: We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS). Results: There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P < 0.001). And in grip strength (%), the results showed a significant improvement in surgical treatment compared with non-surgical treatment (WMD − 6.60, 95% CI (-11.61, -1.60), P = 0.01). There was significant difference in radial inclination, radial length, volar title, range of wrist pronation, range of wrist supination. However, no difference in radial deviation, ulnar deviation, ulnar variance, range of wrist extension and range of wrist flexion was observed. Conclusions: The results of this meta-analysis suggest that some patients with surgical treatment of distal radius fractures not only improved the grip strength (%), decreased the DASH score, but also improved the range of wrist pronation and the range of wrist supination compared with nonsurgical treatment. Based on the present meta-analysis, we suggest that some patients with surgical treatment might be more effective in patients with distal radius fracture. [ABSTRACT FROM AUTHOR]

Results: The study involved a total of 90 patients, consisting of 72 males (80%) and 18 females (20%). The average age of the patients was 10, with a standard deviation of 4.7, ranging from 2 to 16 years. Half of the patients were below the age of 10, accounting for 46 individuals (51%). The causes of the injuries varied among patients below and above the age of 10. However, overall, bullet injuries were the most common cause, accounting for 28 cases (31%), followed by falls in 21 cases (23.3%), horse or donkey kicks in 10 cases (11.1%), stab injuries in 10 cases (11.1%), horn injuries in 7 cases (7.8%), and road traffic accidents in 6 cases (6.7%). Physical assault, blasts, and other types of injuries, such as hen bites and metal rod injuries, were observed in 8 cases (8.9%) of the patients. Fall accidents, horse or donkey kicks, and horn injuries were particularly more common among children below the age of 10, while bullet injuries and stab injuries were most common among those above the age of 10. Conclusion: Following abdominal trauma in children, a range of complications may arise, including immediate issues such as infections and hemorrhaging, as well as long-term consequences like impaired organ functionality and psychological distress. In our region, young children are particularly vulnerable to accidents involving falls, kicks from horses or donkeys, and injuries caused by horns. Therefore, it is crucial to educate parents about these hazards. Additionally, providing appropriate guidance on firearm safety is essential for individuals who possess such weapons.

Understanding the causes of amputation is crucial for defining health policies that seek to avoid such an outcome, but only a few studies have investigated the epidemiology of patients submitted to amputations in developing countries. The objective of this study was to analyse all lower limb amputations performed in the public health system in Brazil over a 13 year period, evaluating trends in the number of cases, patient demographics, associated aetiologies, hospital length of stay, and in hospital mortality rate. This was a retrospective, population based analysis of all lower limb amputations performed in the Brazilian public health system between 1 January 2008 and 31 December 2020. Using a public database, all types of amputations were selected, defining the number of procedures, their main aetiologies, anatomical level of limb loss, demographic data, regional distribution, and other variables of interest. A total of 633 455 amputations were performed between 2008 and 2020, mostly (55.6%) minor amputations, predominantly in males (67%). There was an upward trend in the number of amputations, determined mainly by the increase in major amputations (50.4% increase in the period). Elderly individuals have the highest rates of amputation. Diabetes mellitus (DM) is becoming the main primary diagnosis associated with amputations over the years. The highest in hospital mortality rate occurred after major amputations and was associated with peripheral arterial disease (PAD). Amputation rates in Brazil show an upward trend. DM is becoming the most frequent associated primary diagnosis, although PAD is the diagnosis most associated with major amputations and in hospital death. [ABSTRACT FROM AUTHOR]

Dental implants are a reliable treatment option for restoring missing teeth, but adequate bone quantity and quality are crucial for success. This case series presents four cases treated by different clinicians, all following very similar concepts for combined periodontal and vertical ridge augmentation using recombinant human platelet-derived growth factor-BB. All cases involved a severe periodontal defect requiring either extraction of the adjacent tooth or periodontal regeneration. Different bone grafts and membrane types were utilised. Although true periodontal regeneration cannot be said categorically to have occurred due to a lack of histological evidence, the clinical and radiographic findings suggest almost complete bone fill in all cases. This case series demonstrates that combined periodontal and vertical ridge augmentation using recombinant human platelet-derived growth factor-BB could be successful, but proper case selection and patient preparation for the possibility of multiple surgical procedures are recommended.

Background and Aims: Traditional apprenticeship‐based surgical training presents with challenges, especially in acute scenarios. Simulation provides the current standard of facilitating surgical training in a low‐risk environment but is restricted by limited accessibility and high costs. Virtual reality (VR) offers immersive three‐dimensional computer‐generated training scenarios and can connect users from various locations. We aimed to compare the performance of junior doctors to manage an acute surgical scenario using VR and mannequin‐based simulation. We hypothesised that VR would be as effective as mannequin‐based simulation in performance outcomes. Methods: This multicentre, randomised controlled pilot study was conducted with eighteen junior doctor volunteers (Foundation and Core Trainee Year 1). Ten were randomly allocated to VR and eight to mannequin‐based simulation. Participants completed questionnaires and a 15‐min pneumothorax scenario. Quantitative metrics included overall score, time‐to‐critical decisions, and academic buoyancy scores (ABS). Qualitative metrics included participants' likes and dislikes of their allocated simulation modality. Results: VR participants scored significantly higher than mannequin‐based simulation participants in overall scores (74.30% (SD ± 5.08%) vs. 59.75% (SD ± 10.14) (p = 0.04)), and technical skills aspects (77.20% (SD ± 8.01%) vs. 65.00% (SD ± 8.21%) (p = 0.01)). Mannequin‐based simulation participants initiated critical decisions faster and demonstrated a trend towards a faster mean time‐to‐completion (p = 0.06). ABS scores increased for both study groups, though was only significant for VR participants (p ≤ 0.01). VR participants liked how VR fostered independent learning but disliked the formulaic content and impaired communication‐learning compared to mannequin‐based simulation. Conclusion: Both VR and mannequin‐based simulation training are effective in training junior doctors in acute surgical scenarios but present different educational benefits. Future research should recruit a larger sample size for a full comparative randomised controlled trial. [ABSTRACT FROM AUTHOR]

Anastomotic leak is a significant morbidity in colorectal surgeries. The risk factors for anastomotic leakage are multifactorial with vascularity of the bowel edge playing an important role. Indocyanine green (ICG) dye emits fluorescence and this principle is used to assess the bowel edge vascularity before anastomosis. The context of the study is that even though ICG dye has been used in colorectal cancer surgery for quite a while the evidence is not strong. Most of the data on the role of ICG dye in decreasing the anastomotic leak rate in colorectal cancer surgery comes from retrospective and few prospective trials. There are a few recently published randomized controlled trials (RCT) with contrasting outcomes in this regard. This study is a narrative review of randomized control trials and trial protocols published until 31st December 2023. PubMed, Embase, and Scopus were searched with the keywords ICG, AND Colorectal surgery, AND Anastomotic leak. Four completed RCTs were found and included in this review of all search results. Most of the included studies reported the beneficial effects of ICG on the incidence of anastomotic leak rate. To conclude, the role of ICG dye is not well established in reducing anastomotic leak rates following colorectal anastomosis, but there is growing evidence to support its use. [ABSTRACT FROM AUTHOR]

Background: The COVID‐19 pandemic disrupted the provision of surgical services in Australia. To prepare for a surge of COVID‐19 patients, elective surgery was mandatorily reduced or ceased at multiple timepoints in Australian states between 2020 and 2022. Operative exposure is a critical component of surgical training in general surgery, and readiness for practice is an ongoing priority. However, the impact of COVID‐19 on operative exposure in Australian General Surgical Trainees (AGST) has not been quantified. Methods: This study was a retrospective longitudinal cohort study using de‐identified operative logbook data for Australian General surgical Trainees (AGST) from the Royal Australasian College of Surgeons (RACS) Morbidity and Audit Logbook Tool (MALT) system between February 2019 and July 2021. Bivariate analysis was used to determine the impact of COVID‐19 on general surgical trainees' exposure to operative surgery and trainees' operative autonomy. Results: Data from 1896 unique 6‐month training terms and 543 285 surgical cases was included over the data collection period. There was no statistically significant impact of the COVID‐19 pandemic on AGST operative exposure to major, minor operations, endoscopies, or operative autonomy. Conclusions: The impact of COVID‐19 on surgical trainees globally has been significant. Although this study does not assess all aspects of surgical training, this data demonstrates that there has not been a significant impact of the pandemic on operative exposure or autonomy of AGST.

Purpose: In children with previous obstetrical brachial plexus injury (OBPI), upper extremity pain is present in 45 to 66% of patients. Recent literature reports this as musculoskeletal or neuropathic in nature. The purpose of the study is to demonstrate that peripheral nerve decompression, and neurolysis may be an effective treatment for patients with upper extremity pain in the context of previous OBPI. Methods: A retrospective chart review was performed on patients undergoing peripheral nerve decompression and neurolysis after OBPI by senior author. The primary outcome assessed was pain, and secondary outcome measure was range of motion of the wrist and elbow. Outcome measures were assessed preoperatively as well as at their subsequent follow-up. Results: Six patients were included, with a mean age of 14 years old at time of decompression. Three patients underwent median nerve, two patients underwent ulnar nerve, and one patient underwent posterior interosseous nerve decompression. There was a substantial improvement in pain post-operatively, demonstrated by reduction or resolution of subjective pain in all patients and resolution of Tinel's sign. There was a modest improvement in range of motion. Conclusion: This study demonstrates an improvement in subjective pain and range of motion after decompression and neurolysis in small subset of OBPI patients. It generates the hypothesis that peripheral nerve compression is a source of pain that can be addressed in this population. Future research should focus on confirming this hypothesis and assessing treatment options on a larger scale. [ABSTRACT FROM AUTHOR]

Aim: To develop a nurse‐led model of analgesia to manage post‐operative pain in the surgical neonate. Design: A four‐round e‐Delphi study was conducted from March to December 2022. Methods: An e‐Delphi method was used seeking a consensus of 70% or greater. Fifty‐one experts were invited to join the panel. Members consisted of multi‐disciplinary healthcare professionals who work in areas associated with neonatal care. In round 1, 49 statements relative to neonatal pain assessment and management were distributed to the panel. Panel members were asked to rate their level of agreeance on a Likert scale from 1 to 5 (1 = strongly disagree to 5 = strongly agree). Ratings equal to or greater than 4 represented agreement, 3 indicated uncertainty and 2 or less disagreement with the proposed statement. An opportunity for free‐text responses after each statement was provided. This iterative process continued for three rounds. In the fourth and final round, the completed model of neonatal nurse‐controlled analgesia was presented along with a further opportunity to provide feedback on the final version. Results: Four rounds of statements and voting were required to reach consensus on a model of neonatal nurse‐controlled analgesia. The model consists of criteria for use, over‐arching guidelines and three separate pathways based on an individual baby's pain assessment scores, need for pain relieving interventions and time‐lapsed post‐surgical procedure. Conclusion: A comprehensive model of neonatal nurse‐controlled analgesia, applicable to the Australasian context, was developed in collaboration with a group of neonatal experts. Impact: This study provides a multi‐modal family‐integrated model to manage neonatal post‐operative pain. By providing nurses with increased autonomy to assess and manage acute pain, this model has the potential to not only provide a more responsive and individualized approach to alleviate discomfort, but highlights the integral role of parent partnerships in the neonatal intensive care. Reporting Method: This study was reported in line with the Conducting and REporting of DElphi studies (CREDE) guidance on Delphi studies. Patient or Public Contribution: No patient or public contribution was utilized for this study. [ABSTRACT FROM AUTHOR]

Objective: Non-dissolvable nasal packs (Rapid Rhino and Merocel) are widely used in secondary healthcare centres for the control of epistaxis, with some side effects. Methods: A prospective, observational cohort study was conducted of adults who required Rapid Rhino or Merocel packing for acute epistaxis management in a large healthcare centre between March 2020 and 2021. A validated modified version of the 22-item Sino-Nasal Outcome Test was used. Results: A total of 80 adults requiring non-dissolvable packs were recruited. Seventy per cent of patients had Rapid Rhino packs inserted. Embarrassment was greater in patients who used Rapid Rhino than Merocel. Merocel packs had a significantly higher mean pain score on removal compared to Rapid Rhino. There was no correlation between rebleed rate and type of nasal pack used. Conclusion: Non-dissolvable Rapid Rhino and Merocel nasal packs have similar efficacy in controlling epistaxis. Rapid Rhino packs are more embarrassing for patients in comparison to Merocel packs, but are less painful to remove. [ABSTRACT FROM AUTHOR]

Functional popliteal entrapment syndrome (FPES) is an under-recognized source of leg pain caused by dynamic compression of the popliteal vessels by surrounding musculature in the absence of anatomic abnormality. Late recognition and difficulty capturing this entity across imaging modalities can lead to significant morbidity in an often young and active patient population. Surgical outcomes and optimal diagnostic strategies remain uncertain. We performed a retrospective cohort study of all patients undergoing surgical decompression for FPES at an academic medical center between 2018 and 2022. Preoperative symptoms, patient characteristics, imaging, operative details, and follow-up were captured. The primary outcome was symptomatic improvement at last clinic visit. Secondary outcomes included symptomatic improvement at 6 months and postoperative complications. A total of 24 extremities (16 patients) were included. The mean ± standard deviation age was 23.3 ± 6.4 years and 75.0% of patients were female. The median symptom duration before decompression was 27 months (interquartile range, 10.7-74.6 months). Preoperative symptom severity in the affected extremity was as follows: 33.3% limited from peak exercise, 25% unable to exercise, and 41.7% with debilitating symptoms that affected activities of daily living. Preoperative imaging with provocative maneuvers included duplex ultrasound (87.5%), magnetic resonance angiography (100%), and digital subtraction angiography (100%). Using digital subtraction angiography as the gold standard, the sensitivity for detection of FPES was 85.7% for duplex examination and 58.3% for magnetic resonance angiography. The median follow-up was 451 days (interquartile range, 281-635 days). Most patients demonstrated durable improvement in the affected extremity, with 29.2% realizing complete resolution of symptoms and 37.5% reporting symptomatic improvement at last clinic visit for a total of 66.7%; 20.8% had initial improvement, but developed recurrent symptoms and were found to have elevated compartment pressures consistent with chronic exertional compartment syndrome and were treated with formal fasciotomy. Repeat decompression was required in one extremity (4.2%) owing to recurrent symptoms. Two patients (8.3%) had minimal or no improvement in their affected extremity and workup for the cause of continued discomfort was ongoing. Delays in diagnosis of FPES are common. Provocative maneuvers until replication of symptoms across multiple imaging modalities may be necessary to reliably identify the disease process. Surgical decompression improved or completely resolved symptoms in two-thirds of extremities. Treating physicians should maintain suspicion for comorbid chronic exertional compartment syndrome, especially if symptoms recur or persist after decompression. [ABSTRACT FROM AUTHOR]
