Objectives: Inherent technical aspects of pulmonary lobectomy by video-assisted thoracoscopic surgery (VATS) may limit surgeons' ability to deal with factors predisposing to complications. We analysed complication rates after VATS lobectomy in a prospectively maintained nationwide registry., Methods: The registry was queried for all consecutive VATS lobectomy procedures from 49 Italian Thoracic Units. Baseline condition, tumour features, surgical techniques, devices, postoperative care, complications, conversions and the reasons thereof were detailed. Univariable and multivariable regressions were used to assess factors potentially linked to complications., Results: Four thousand one hundred and ninety-one VATS lobectomies in 4156 patients (2480 men, 1676 women) were analysed. The median age-adjusted Charlson index of the patients was 4 (interquartile range 3-6). Grade 1 and 2 and Grade 3-5 complications were observed in 20.1% and in 5.8%, respectively. Ninety-day mortality was 0.55%. The overall conversion rate was 9.2% and significantly higher in low-volume centres (<100 cases, P < 0.001), but there was no significant difference between intermediate- and high-volume centres under this aspect. Low-volume centres were significantly more likely to convert due to issues with difficult local anatomy, but not significantly so for bleeding. Conversion, lower case-volume, comorbidity burden, male gender, adhesions, blood loss, operative time, sealants and epidural analgesia were significantly associated with increased postoperative morbidity., Conclusions: VATS lobectomy is a safe procedure even in medically compromised patients. An improved classification system for conversions is proposed and prevention strategies are suggested to reduce conversion rates and possibly complications in less-experienced centres., (© The Author(s) 2019.

Objectives: No study evaluated the contribution of adjunctive surgery in bedaquiline-treated patients. This study describes treatment outcomes and complications in a cohort of drug-resistant pulmonary tuberculosis (TB) cases treated with bedaquiline-containing regimens undergoing surgery., Methods: This retrospective observational study recruited patients treated for TB in 12 centres in 9 countries between January 2007 and March 2015. Patients who had surgical indications in a bedaquiline-treated programme-based cohort were selected and surgery-related information was collected. Patient characteristics and surgical indications were described together with type of operation, surgical complications, bacteriological conversion rates, and treatment outcomes. Treatment outcomes were evaluated according to the time of surgery., Results: 57 bedaquiline-exposed cases resistant to a median of 7 drugs had indication for surgery (52 retreatments; 50 extensively drug-resistant (XDR) or pre XDR-TB). Sixty percent of cases initiated bedaquiline treatment following surgery, while 36.4% underwent the bedaquiline regimen before surgery and completed it after the operation. At treatment completion 90% culture-converted with 69.1% achieving treatment success; 21.8% had unfavourable outcomes (20.0% treatment failure, 1.8% lost to follow-up), and 9.1% were still undergoing treatment., Conclusions: The study results suggest that bedaquiline and surgery can be safely and effectively combined in selected cases with a specific indication., (Copyright © 2018 The British Infection Association.

The traditional approach to thymectomy requires median sternotomy based on the assumption that it is the best means to achieve adequate resection margins, complete removal of the thymus and clearance of the anterior mediastinal fat. However, in recent years, VATS thymectomy has been gaining acceptance as a means to achieve adequate oncologic results and symptomatic improvement of myasthenic symptoms with less impact on the patient. We have adopted a flexible approach based on the location of the tumor and on whether the patient has myasthenia gravis (MG) or not when planning minimally invasive VATS thymectomy. A preferential approach from the left side is chosen for clinical stage I-II thymomas located on the left side or on the midline in patients without MG, and a bilateral approach (uniportal VATS on the right side and three-portal VATS on the left side) for MG patients with or without thymoma in order to achieve complete clearance of the anterior mediastinal fat on both sides. Such techniques are herewith clearly illustrated in hope that surgeons wishing to endeavor in such an effort will be facilitated., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

EBUS-TBNA is gaining widespread acceptance as a minimally invasive procedure for mediastinal staging and re-staging of lung cancer, diagnosis of lung tumors adjacent to large airways and characterization of both malignant and benign lymphadenopathy. The aim of this article is to describe the appropriate setting and practical aspects of the procedure that may help at the start of a new EBUS-TBNA program to improve patient safety, comfort and procedural yield according to operator experience, procedure aim, and institutional needs., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Thoracic surgeons have limited experience with treating localized organizing pneumonia owing to its rare occurrence in routine clinical practice., Methods: We retrospectively investigated the clinicopathologic features of 21 patients with localized organizing pneumonia observed between 2001 and 2004., Results: There were 15 men and 6 women. Mean age was 63 years. Eight patients (38%) were symptomatic. Computed tomographic scan showed a single lesion in 17 patients (12 nodules and 5 masses) and bilateral lesions in 4. Wedge resection was performed in 16 patients and lobectomy in 5. There was no operative mortality. Follow-up was complete in all patients (range, 2 to 46 months; median, 20 months). Surgery was curative in 15 of 17 patients with a single lesion, and no recurrence was observed (p < 0.005). The remaining 2 patients with a single lesion (2 masses) had a local relapse with the appearance of nodular lesions in the residual parenchyma. Both these patients received steroids with resolution of the lesions. All 4 patients with bilateral lesions who underwent surgery for diagnostic purposes received steroids with improvement of the radiologic aspect in 3 and stabilization of the lesions in 1., Conclusions: Clinical and radiologic findings of localized organizing pneumonia are nonspecific, and this unusual entity is difficult to differentiate from a primary or metastatic tumor. Surgical resection allows both diagnosis and cure. However, considering the benignity of the lesion and the efficacy of steroids, major pulmonary resections should be avoided.

Objective: Persistent air leak is among the most common complications after pulmonary resection, leading to prolonged hospitalization and increased costs. At present there is not yet a consensus on their treatment., Methods: During a 7-year experience, 21 patients submitted to pulmonary resection were postoperatively treated with an autologous blood patch for persistent air leaks. Persistent air leaks were catalogued twice daily according to the classification previously reported by Cerfolio and associates. Chest radiographs showed a fixed pleural space deficit in 18 (86%) patients. A total of 50 to 150 mL of autologous blood was drawn from the patient and injected into the chest tube, which was removed 48 hours after cessation of the air leak., Results: We observed a 4% incidence of persistent air leaks after pulmonary resection in our series. Persistent air leaks were categorized as follows: 14% forced expiratory, 57% expiratory, 29% continuous, and 0% inspiratory. The mean duration of prolonged air leaks was 11 days after surgery. In 81% of the cases examined, a blood patch was only carried out once and gave successful results within 24 hours. In the remaining 19% of cases, the air leak ceased within 12 hours after the second procedure. Mean hospital stay was 15 days. In our experience this procedure had a 100% success rate., Conclusions: Pleurodesis with an autologous blood patch is well tolerated, safe, and inexpensive. This procedure is an effective technique for treatment of postoperative persistent air leaks, even in the presence of an associated fixed pleural space deficit.

Objectives: In patients with non-small cell lung cancer (NSCLC) the presence of satellite metastatic nodules may be considered a contraindication to surgical treatment. The use of spiral computed tomography (CT) scan has improved the accuracy of the diagnostic assessment of pulmonary diseases, but has also led to the detection of a consistent number of indeterminate satellite lesions. Obtaining a differential diagnosis of these lesions is extremely important in defining the therapeutic strategy. The aim of the study was to assess the characteristics of satellite nodules in patients with NSCLC and to examine the diagnostic and therapeutic approach used in the presence of indeterminate satellite lesions., Methods: From November 1995 to February 2001, 29 patients (mean age 64 years) who underwent surgery for NSCLC had indeterminate satellite pulmonary lesions at the preoperative spiral CT scan. A differential diagnosis of the nodules was obtained by histological examination in 27 patients and by follow-up (62 and 64 months, respectively) in two patients. Positron emission tomography (PET) scan was selectively performed in the preoperative evaluation., Results: Thirty-two satellite nodules were analyzed in the group of 29 patients. The size of the lesions varied from 2 to 15 mm (mean 8mm). The nodules were ipsilateral to the primary tumor in 25 patients and contralateral in four. They were benign in 22 cases and malignant in ten (metastases from NSCLC in seven patients and second primary lung cancer in three). Nodules with a size equal to or less than 5mm were more frequently benign. Patients with stage III tumors had a higher incidence of malignant satellite nodules in comparison to earlier stages, although the data did not reach statistical significance. PET scan correctly differentiated benign and malignant satellite nodules in six patients., Conclusions: Obtaining a differential diagnosis of indeterminate pulmonary nodules associated to NSCLC is of great importance in defining the therapeutic strategy. The results of this study show that indeterminate satellite lesions may be benign or represent a second primary lung cancer, and should not therefore be considered a contraindication to surgical exploration when a preliminary differential diagnosis by other means cannot be obtained.

Due to the severity of respiratory symptoms, congenital lobar emphysema often requires surgical treatment in the early stages of life. Diagnosis of congenital lobar emphysema in adult life is therefore unusual, often presenting with mild symptoms. Diagnostic assessment is therefore of great importance in the treatment of these patients. A case of congenital lobar emphysema in an adult is reported and the diagnostic and therapeutical approach are discussed. The use of new diagnostic techniques such as dynamic RMN and SPET V/Q lung scan may improve the accuracy of the diagnostic evaluation. Pulmonary lobectomy led to marked improvement in respiratory function. Accurate diagnosis and appropriate management of congenital lobar emphysema in adult patients can lead to favourable results.

Background: Tracheal resection and reconstruction is the standard treatment for postintubation stenosis. However, when the stenosis extends proximally to the subglottic larynx surgical treatment is particularly difficult. Specific surgical techniques have to be used in order to preserve the recurrent laryngeal nerves. The aim of this study is to evaluate the results obtained at our Department with laryngotracheal resection and reconstruction with the Grillo technique for postintubation stenosis., Methods: From January 1984 to December 1997, 83 patients with tracheal and laryngotracheal lesions underwent surgical treatment. Eighteen patients had postintubation stenosis of the upper trachea and subglottic larynx and underwent single-stage laryngotracheal resection and reconstruction. Mean stenosis length was 3.5 cm (range 3-5 cm). Twelve patients underwent anterolateral laryngotracheal reconstruction, and 6 patients had a circumferential laryngotracheal reconstruction. A Montgomery suprahyoid laryngeal release was required in 4 cases., Results: There was no surgical mortality. Surgical results were excellent or good in 17 cases and satisfactory in one case. No recurrence of stenosis has been observed., Conclusions: Cricoid cartilage involvement in postintubation stenosis should not be considered a contraindication to surgical treatment. However, laryngotracheal resection and reconstruction is technically difficult and should be performed only in selected cases.

Background: Indications to surgical treatment of lung cancer in the elderly are still being discussed. The aim of this study was to evaluate postoperative complications and survival after surgery for non-small cell lung cancer (NSCLC) in patients 70 years of age or older., Methods: During a 4 year and 6 month period, 76 patients (67 men and 9 women) entered the study., Results: Postoperative complications occurred in 15 cases (19.7%) and the 30-day operative mortality was 1.3%. The overall 54 month actuarial survival was 53%. Mortality at 12 months wasn't related to stage of disease, histology or lobectomy versus wedge resection but was higher in those patients who had had postoperative cardiopulmonary complications. Results of preoperative spirometry, blood gas and cardiac status were predictive of mortality at twelve months (p < 0.05)., Conclusions: Surgery for NSCLC in the elderly should not be denied on the basis of age alone. Postoperative outcome is mainly related to concomitant cardiopulmonary disease.
