RESUMO
BACKGROUND: Sleeve lobectomy represents a safe and effective treatment for central NSCLC to avoid the risks of pneumonectomy. Induction therapy (IT) may be indicated in advanced stages; however, the effect of IT on bronchial anastomoses remains uncertain. The purpose of the study was to evaluate the impact of IT on the complications of the anastomoses. METHODS: Between 2000 and 2012, 159 consecutive patients were submitted to sleeve lobectomy for NSCLC at our Institution. We retrospectively compared the results of patients who underwent IT before operation with those who received upfront surgery. RESULTS: In the study period, 49 (30.8%) patients received IT (37 chemotherapy, 1 radiotherapy and 11 chemo-radiotherapy) and 110 (69.2%) patients were directly submitted to surgery (S). The two groups were comparable for sex, age, comorbidities, ASA score, pulmonary function, side, type of procedure and histology. Pathological stage was statistically higher for IT group (p = 0.001). No differences between IT and S groups were observed in terms of post-operative mortality (2% vs 0%, p = NS), morbidity (45% vs 38%, p = NS), including early (6% vs 9%, p = NS) and long-term (16% vs 14%, p = NS) bronchial complication rates. Patients undergoing induction mediastinal radiotherapy, however, are at higher risk of bronchial complications. CONCLUSION: In our experience, the use of induction chemotherapy did not significantly increase mortality and morbidity rates, in particular, neither for early nor for late anastomotic complications. We, therefore, conclude that sleeve lobectomy after induction chemotherapy is safe and reliable procedure for the treatment of locally advanced NSCLC.

Chest tube management represents a major issue after lung surgery as no protocol is widely accepted and tube management is generally based on local or personal habits. Aim of this study is to evaluate the impact of a standardized protocol for chest tube management after pulmonary resections on the post-operative outcomes. We performed a single center retrospective analysis of all adult patients undergoing thoracoscopic pulmonary resection from January 2020 to December 2021. Starting from January 2021 a standardized protocol of chest tube management was applied after all procedures. Patients were divided into two groups according to the chest tube management strategy. he two groups had similar pre-operative characteristics and the extent of lung resection was comparable. Intervention group had significantly shorter time to chest tube removal (median 1 vs 3 days, p < 0.001) and post-operative length of stay (median 3 vs 4 days, p < 0.001). Despite earlier chest tube removal, there was not an increased incidence of post-removal complications. On multivariable analysis, the new chest drain management strategy was an independent predictor of earlier chest tube removal. A standardized protocol of chest tube management allows for an earlier chest tube removal and a shorter hospital stay, without an increase in post-operative complications.
RESUMO
BACKGROUND: The involvement of mediastinal great vessels is common in advanced stage thymic tumors, which makes their surgical resection challenging. Moreover, the impact of vascular involvement on the oncological prognosis is still unclear. The aim of this study is to investigate the surgical and oncological outcomes and the impact of vascular involvement in a population of patients operated for advanced stage thymic tumors. METHODS: A retrospective analysis on four hundred and sixty-five patients undergoing resection for advanced stage (Masaoka III-IV) thymic tumors in a single high-volume center was performed. One hundred forty-four patients met the inclusion criteria and were eligible for the study. Patients were divided in two groups according to the presence or absence of vascular involvement. RESULTS: the two groups did not differ for the baseline characteristics and showed comparable surgical outcomes. Vascular involvement was not associated with worse overall survival but with an increased recurrence rate (p = 0.03). Multivariable analysis demonstrated a higher risk of recurrence in patients without R0 resection (HR 0.11, 0.02-0.54, p = 0.006) and with thymic carcinoma (HR 2.27, 1.22-4.24, p = 0.01). CONCLUSIONS: resection of thymic tumors with vascular involvement can be performed with optimal surgical results in a high volume center. From the oncological point of view, the involvement of the great vessels seems to be associated with a higher recurrence rate without affecting long-term survival.
RESUMO
Airway dehiscence after tracheal resection-anastomosis is a major complication that often requires an urgent reoperation. If ischaemia of the airway is extensive, however, performing a tracheostomy might be complicated. Here, we describe the case of a patient who underwent urgent tracheostomy because of acute airway dehiscence, wherein an absorbable prosthesis was used to repair the defect of the anterior trachea.

BACKGROUND: This group previously reported on the repair of a wide tracheoesophageal fistula with a bioabsorbable patch. The current study describes a consecutive series of patients operated on using the same technique. METHODS: Data of patients undergoing surgical closure of tracheoesophageal fistula at a single center from 2011 to 2018 were extracted and analyzed. RESULTS: An absorbable patch was used in 8 of 23 patients (34.8%) operated on for tracheoesophageal fistula during the study period. Causes of the fistulae included postintubation injury (n = 6), mediastinal radiotherapy (n = 1), and a complication of lung resection (n = 1). The median fistula size was 27.5 mm (range, 15 to 45 mm). In 3 patients, the surgical approach was through cervicotomy and in 5 it was through right thoracotomy. Prosthetic materials consisted of Gore Bio-A (W.L. Gore & Associates, Inc, Newark, DE) tissue reinforcement in 6 patients and polyglactin 910 knitted mesh in 2 patients. In every case, the prosthesis was covered with a pedicled muscle flap. The esophageal defect was treated by primary closure in 7 patients and by esophageal exclusion in 1. Fistula recurrence and postoperative death occurred in 1 patient (12.5%), whereas 7 patients experienced postoperative complications (87.5%). Five patients resumed oral intake, and 3 breathed without a tracheal appliance. Compared with the other patients, in those who underwent repair of their fistula using a prosthesis, the median size of the airway defect was larger, morbidity was greater, and the rate of resumption of oral intake was lower. CONCLUSIONS: Repair of tracheoesophageal fistulae with synthetic prostheses is feasible and may be effective in complex cases. Further research is needed to identify the ideal prosthetic material.

About 15% of patients with myasthenia gravis are affected by thymoma. Precise tumor staging is necessary to plan the appropriate operation. In early stages, complete surgical resection is the mainstay of treatment. Minimally invasive approaches can be safely performed by highly trained surgeons, and may be preferred in myasthenic patients because they can ensure optimal results from the oncological, neurologic, and surgical point of views, avoiding the complications of open approach. For advanced stage thymoma in myasthenic patients, a careful, multidisciplinary planning of the therapeutic approach must be undertaken, particularly for extended resections involving the lung and great vessels.

BACKGROUND: In patients submitted to major pulmonary resection, the postoperative length of stay is mainly influenced by the duration of air leaks and chest tube removal. The measurement of air leaks largely relies on traditional chest drainage systems which are prone to subjective interpretation. Difficulty in differentiating between active air leaks and bubbles due to a pleural space effect may also lead to tentative drain clamping and prolonged time for chest drain removal. New digital systems allow continuous monitoring of air leaks, identifying subtle leakage that may be not visible during daily patient evaluation. Moreover, an objective assessment of air leaks may lead to a reduced interobserver variability and to an optimized timing for chest tube removal. METHODS: This study is a prospective randomized, interventional, multicenter trial designed to compare an electronic chest drainage system (Drentech™ Palm Evo) with a traditional system (Drentech™ Compact) in a cohort of patients undergoing pulmonary lobectomy through a standard three-port video-assisted thoracic surgery approach for both benign and malignant disease. The study will enroll 382 patients in three Italian centers. The duration of chest drainage and the length of hospital stay will be evaluated in the two groups. Moreover, the study will evaluate whether the use of a digital chest system compared with a traditional system reduces the interobserver variability. Finally, it will evaluate whether the digital drain system may help in distinguishing an active air leak from a pleural space effect, by the digital assessment of intrapleural differential pressure, and in identifying potential predictors of prolonged air leaks. DISCUSSION: To date, few studies have been performed to evaluate the clinical impact of digital drainage systems. The proposed prospective randomized trial will provide new knowledge to this research area by investigating and comparing the difference between digital and traditional chest drain systems. In particular, the objectives of this project are to evaluate the feasibility and usefulness of digital chest drainages and to provide new tools to identify patients at higher risk of developing prolonged air leaks.

BACKGROUND: In the last decades, the use of video-assisted thoracoscopic surgery (VATS) lobectomy for the treatment of early stage non-small cell lung cancer is continuously growing. This is mainly due to the development of more advanced surgical devices, to the rising incidence of peripheral lung tumors and is also favored by the increased reliability of preoperative staging techniques. Despite this progress, postoperative unexpected nodal upstaging is still a relevant issue. Aim of this study is to identify possible predictors of unexpected nodal upstaging in patients affected by cT1-3N0 NSCLC submitted to VATS lobectomy. METHODS: A total of 231 cases of cT1-3N0 patients submitted to thoracoscopic lobectomy at our centre between June 2012 and October 2016 were retrospectively reviewed. All data regarding clinical staging by means of computed tomography (CT) and positron-emission tomography (PET)/CT were collected and reviewed. The subsequent pathological staging has been analyzed, with special regards to the possible type of nodal involvement, and the number of pathological nodal stations. RESULTS: Most of the patients included in this study were in a clinical stage cT1aN0, cT1bN0 (stage IA) and cT2aN0 (stage IB), 86 (37.2%) patients, 73 (31.6%) patients and 62 (26.8%) patients, respectively. Postoperative histopathological analysis showed that the most frequent tumor histotype was adenocarcinoma (192 patients, 83.1%). Thirty-eight (16.5%) patients had a nodal upstaging; among these, 17 (7.4%) patients had N2 disease (8 patients with isolated mediastinal nodal involvement, 9 patients with N1 + N2 disease) and 21 (9.1%) patients had an isolated hilar nodal involvement (N1). At bivariate analysis, the clinical T (cT)-parameter (P=0.023), the histotype (P=0.029) and the pathological T (pT)-parameter (P=0.003) were identified as statistically significant predictors of nodal upstaging. Concerning the type of nodal upstaging, the pT was found to be statistically significant (P=0.042). At bivariate analysis for the number of involved nodal stations, a statistical significance was highlighted for the parameters cT (P=0.030) and pT (P=0.027). With linear logistic regression, histology as well as pT reached statistical significance (P=0.0275 and P=0.0382, respectively). No correlation was found between nodal upstaging and the intensity of FDG uptake in the primary lung tumor or with the timing between PET and surgery. CONCLUSIONS: There is a strong correlation between the clinical staging of the parameter T evaluated with CT and the possible unexpected nodal upstaging. The same correlation with nodal upstaging is found for pT. At equal clinical stage, in patients affected by adenocarcinoma of the lung the relative risk of having a postoperative unexpected nodal upstaging is almost 7 times higher than in patients with squamous cell carcinoma.
RESUMO
Thymectomy is the cornerstone in the treatment of thymic tumors and an accepted option for the management of myasthenia gravis. Different surgical approaches have been described, but the gold standard is represented by median sternotomy. In the last two decades, the development of minimally invasive surgery has led to an increased acceptance of thymectomy, especially for benign diseases. Robotic thymectomy seems a further step in the development and evolution of minimally invasive approaches. Since its introduction, different authors described their experience with robotic thymectomy, both for nonthymomatous myasthenia gravis and for thymic tumors. Available data show that robotic thymectomy may be considered a safe and feasible operation. In patients with nonthymomatous myasthenia, robotic thymectomy is effective and the long-term results are encouraging. The role of robotic thymectomy in patients affected by thymoma is still under evaluation, but the intermediate results seem promising both in terms of surgical and oncologic outcomes.
RESUMO
BACKGROUND: Robotic thymectomy for early-stage thymomas has been recently suggested as a technically sound and safe approach. However, due to a lack of data on long term results, controversy still exists regarding its oncological efficacy. In this multi-institutional series collected from four European Centres with high volumes of robotic procedures, we evaluate the results after robot-assisted thoracoscopic thymectomy for thymoma. METHODS: Between 2002 and 2014, 134 patients (61 males and 73 females, median age 59 years) with a clinical diagnosis of thymoma were operated on using a left-sided (38%), right-sided (59.8%) or bilateral (2.2%) robotic approach. Seventy (52%) patients had associated myasthenia gravis (MG). RESULTS: The average operative time was 146 minutes (range, 60-353 minutes). Twelve (8.9%) patients needed open conversion: in one case, a standard thoracoscopy was performed after robotic system breakdown, and in six cases, an additional access was required. Neither vascular and nerve injuries, nor perioperative mortality occurred. A total of 23 (17.1%) patients experienced postoperative complications. Median hospital stay was 4 days (range, 2-35 days). Mean diameter of resected tumors was 4.4 cm (range, 1-10 cm), Masaoka stage was I in 46 (34.4%) patients, II in 71 (52.9%), III in 11 (8.3%) and IVa/b in 6 (4.4%) cases. At last follow up, 131 patients were alive, three died (all from non-thymoma related causes) with a 5-year survival rate of 97%. One (0.7%) patient experienced a pleural recurrence. CONCLUSIONS: Our data suggest that robotic thymectomy for thymoma is a technically feasible and safe procedure with low complication rates and short hospital stays. Oncological outcome appears to be good, particularly for early-stage tumors, but a longer follow-up period and more cases are necessary in order to consider this as a standard approach. Indications for robotic thymectomy for stage III or IVa thymomas are rare and should be carefully evaluated.
