RESUMO
Background: Elective extra-corporeal membrane oxygenation (ECMO) is rarely used in thoracic surgery, apart from lung transplantation. The purpose of this study was to summarize our institutional experience with the intraoperative use of veno-venous (VV) ECMO in selected cases of main airway surgery. Methods: We retrospectively analyzed the data of 10 patients who underwent main airway surgery with the support of VV-ECMO between June 2013 and August 2022. Results: Surgical procedures included: three carinal resection and reconstruction with complete preservation of the lung parenchyma, one right upper double-sleeve lobectomy and hemi-carinal resection, and one sleeve resection of the left main bronchus after previous right lower bilobectomy, for thoracic malignancies; four tracheal/carinal repair for extensive traumatic laceration; one extended tracheal resection due to post-tracheostomy stenosis in a patient who had previously undergone a left pneumonectomy. The median intraoperative VV-ECMO use was 162.5 minutes. In three cases with complex resection and reconstruction of the carina and in one case of extended post-tracheostomy stenosis and previous pneumonectomy, high-flow VV-ECMO allowed interruption of ventilation for almost 3 hours. In four patients, VV-ECMO was prolonged in the postoperative period to ensure early extubation. There were no perioperative deaths, no complications related to the use of ECMO and no intraoperative change in the planned type of ECMO. Significant complications occurred only in one patient who developed a small anastomotic dehiscence that led to stenosis and required placement of a Montgomery tube. At the median follow-up of 30 months, all 10 patients were still alive. Conclusions: The use of intraoperative VV-ECMO allows safe and precise performance of main airway surgery with minimal postoperative morbidity in patients requiring complex resections and reconstructions and in cases that cannot be managed with conventional ventilation techniques.
RESUMO
BACKGROUND: Standard sleeve lobectomies are recommended over pneumonectomy (PN), but the efficacy and oncological proficiency of complex sleeve lobectomies (CSLs) have not been completely investigated. The aim of this study was to report our experience in CSL in patients affected by a centrally located non-small-cell lung cancer (NSCLC), comparing all the variables and outcomes with PN. METHODS: From 2014 to 2022, we collected the data of patients who underwent PN and CSL for NSCLC, excluding neuroendocrine tumors, salvage surgery or carinal resection. Regression analysis was used to assess the association between procedures and complications; the Kaplan-Meier method and Cox regression analysis were used to evaluate survival and risk factors of reduced survival. RESULTS: We analyzed n = 38 extended sleeve lobectomies and n= 6 double-sleeve lobectomies (CSL group) and n= 60 PNs. We had a trend toward higher postoperative mortality in the PN group (5% vs. 0%, p = 0.13). Major complications and bronchial fistula developed in 21.7% and 6.8% (p = 0.038) and in 6.7% and 4.5% (p = 0.64), respectively. The right side was identified as risk factor for major complications, whereas age > 70 and PN had a trend of association in multivariable analysis. The median OS was similar between the two groups (p = 0.76) and cancer recurrence was the only significant risk factors of reduced OS. Excluding functionally compromised patients, the OS of CSL was better than that of PN (67% vs. 42%, p = 0.25). CONCLUSIONS: Considering that major complications are often associated with mortality after surgery for centrally located NSCLC, CSLs could be considered an alternative to PN while also ensuring comparable survival.
RESUMO
BACKGROUND: The role of video-assisted thoracoscopic segmentectomy in the treatment of clinical IA non-small-cell lung cancer is not well established. The aim of our retrospective analysis was to evaluate the oncological results of complex and simple video-assisted thoracoscopic segmentectomy. METHODS: From 2015 to June 2020, data of n = 163 consecutive patients undergoing video-assisted thoracoscopic segmentectomy for solitary pulmonary nodule were analysed. The Kaplan-Meier method, log-rank test and Cox regression were used to estimate, compare survivals and identify risk factors of worse oncological outcomes. RESULTS: In this period, n = 123 patients underwent video-assisted thoracoscopic segmentectomy for non-small-cell lung cancer: we performed n = 65 simple and n = 58 complex video-assisted thoracoscopic segmentectomy; n = 99 (80.5%) had a solid appearance on computed tomography scan and n = 78 (63.4%) a moderate-to-high [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomographic computed tomography scan avidity. Mortality was 0%, and complications occurred in n = 14 (21.5%) and 9 (15.5%) patients. The median follow-up was 24 (range: 6-60) months and the 5-year overall survival was 96% without difference between video-assisted thoracoscopic segmentectomies (p = 0.16). Local recurrence developed in n = 2 (3.1%) and n = 3 (5.2%) patients; regional in n = 2 (3.1%) and 1 (1.8%) and distant in 8 (12.3%) and 2 (3.4%), without difference between video-assisted thoracoscopic segmentectomies (p = 0.51). The overall 5-year disease-free survival rate was 78%. Pathological upstaging was observed in n = 13 patients (nodal in n = 6, tumour in n = 7) and it was the only significant factor for worse disease-free survival at the multivariable analysis (hazard ratio: 2.43, 95% CI: 1.04-8.68, p = 0.049), value confirmed also in the group of intended video-assisted thoracoscopic segmentectomy (p = 0.047). CONCLUSIONS: Pathological upstaging after simple or complex video-assisted thoracoscopic segmentectomy is a risk factor for recurrence and then video-assisted thoracoscopic segmentectomy should be considered an appropriate therapeutic option for selected stage IA non-small-cell lung cancer patients.

Objectives: Since its introduction, the Nuss minimally invasive procedure for pectus excavatum (PE) repair (MIRPE) has become the method of choice. The current study describes our experience of PE correction in adults, with particular focus on postoperative outcomes, pain, quality of life, and patients' satisfaction. Methods: We enrolled for this observational study n = 93 adult patients from 2011 to 2018. The Haller index was used to quantify PE severity. Pulmonary function tests and cardiac examinations were performed preoperatively; we developed a standardized surgical technique and postoperative treatment, including follow-up at 3, 12, and 24 months after surgery and 6 months after bar removal. We also evaluated the quality of life and the satisfaction with the cosmetic result after the procedure with standardized questionnaires. Results: No operative or perioperative deaths occurred nor life-treating complications. Thirteen complications occurred in 12 patients, with a total complication rate of 14% (n = 13/93). Pain intensity decreased in the follow-up [pain score visual analog scale at 3 months: median 1 (0-8); 12 months: median 1 (0-5); and 24 months: median 1 (0-4)]. Better or much better quality of life after the Nuss procedure was observed: n = 79 (84.1%) at 3 months, n = 80 (86%) at 12 months, and n = 85 (91.4%) at 24 months. After 2 years of observation, more than 90% of patients described improvement in their quality of life and satisfaction with the cosmetic results. Only a very small group of patients suffered from pain in the follow-up. Conclusion: Our results demonstrate that the MIRPE procedure is safe and can be performed with excellent results in adults both for improvement of quality of life and for satisfaction with cosmetic results.
RESUMO
BACKGROUND: Thoracoscopic lobectomy (VATS-L) for non-small-cell lung cancer (NSCLC) is a well-established option for early stage NSCLC, but the evidences are limited for octogenarians. OBJECTIVE: The objectives of this multi-institutional study were to evaluate the post-operative outcomes of VATS-L in octogenarians and to estimate the post-operative quality of life (QoL) using a validated questionnaire (EuroQoL5D). METHODS: Data from patients underwent VATS-L between 2014 and 2019 were analysed and divided into two groups: Group A (younger patients) and Group B (octogenarians). To define predictors for complications, univariate and multivariable logistic regression analysis were performed. RESULTS: 7023 patients underwent VATS-L and 329 (4.6%) were octogenarians. 30-day and 90-day post-operative mortality were similar (0.95% vs 0.91%, p = 0.84 and 1.3% vs 1.2%, p = 0.58), whereas the percentage of patients who suffered from any complication (25.5% vs 31.9%, p = 0.012) and the complication rate (31.6% vs 45.2%, p=<0.01) were higher for octogenarians. At discharge, the values of EuroQoL5D were worse in group B, but after one month these levels became similar. Age >80 years had a significant influence on morbidity on both univariate and multivariable analyses (p = 0.025). CONCLUSIONS: VATS-L for NSCLC can be performed in selected octogenarians without increased risk of post-operative death, acceptable not-life-threatening complications and a moderate impact on QoL.

BACKGROUNDS: The aim of this study was to report our Institutional experience with extended sleeve lobectomy (ESL) in centrally located non-small cell lung cancer (NSCLC), focusing on technical details, post-operative results, recurrence and survival, to determine whether ESL can be accepted as a favorable alternative procedure to pneumonectomy (PN). METHODS: Twenty-two consecutive patients undergoing ESL for centrally located tumors from January 2014 to June 2019 were prospectively enrolled. RESULTS: Six (27.3%) patients had been preoperatively considered unfit for PN. Neo-adjuvant chemotherapy was administered in 7 (31.8%) out of the 10 patients that showed a cN2 disease. According to Okada classification, 8 cases of type A ESL (resection of right upper plus middle lobe ± segment 6), one case of type B (resection of left upper lobe + segment 6) and 13 cases of type C (resection of left lower lobe + lingulectomy) ESL were performed. Concomitant pulmonary angioplasty was done in 7 (31.8%) patients. Complete resection was achieved in all patients. There was no postoperative mortality. Major postoperative complications developed in 2 (9.1%) patients (one small anastomotic dehiscence healed in few weeks, one pulmonary embolism). Complete long-term patency of the reconstructed airway was documented in all patients by fiber-optic bronchoscopy. At the median follow-up of 21 months (4-57 months), the recurrence rate was 54.5%, with 4 (18.2%) patients developing a loco-regional recurrence but no endobronchial or perianastomotic recurrence occurred. The overall 3-year survival rate was 45% with a median survival of 33 months. CONCLUSIONS: ESL is a safe and effective procedure that should be considered a favorable alternative to PN whenever it may guarantee a complete resection.
RESUMO
OBJECTIVE: Multimodality treatments are effective for locally advanced non-small cell lung cancer (LA-NSCLC) showing benefits in overall (OS) and disease-free survival (DFS), but these options are frequently denied to elderly patients. METHODS: The objectives of this retrospective study were: to investigate mortality, morbidity and oncological outcomes of pulmonary resection after induction therapy (IT) for NSCLC in elderly patients. We divided the cohort into two: patients < 70 years (group A) and patients ≥70 years (group B). A multivariable logistic regression was built to identify factors associated with morbidity. RESULTS: 77 patients underwent pulmonary resection after IT, 27 were aged ≥70 years. Type of chemotherapy, surgical procedures, pathological stages were comparable between the two groups, while the preoperative use of chemo-radiation therapy regimen was more frequent in group A (p = 0.027). In-hospital mortality was similar, while the percentage of patients with complications (38% vs 48.1%, p = 0.47) and the complication rate (50% vs 77%, p = 0.01) were higher in group B, but the severity of complications was comparable. The multivariable analysis did not identify any risk factors associated with morbidity. OS at 3 years and DFS at 2 years were not different (61% vs 48.5%, p = 0.64; 61.7% vs 44%, p = 0.393). CONCLUSIONS: Lung resection for LA-NSCLC after IT can be performed safely in selected elderly patients with favourable postoperative and mid-term oncological results.

OBJECTIVES: The objective of this retrospective multi-institutional study was to evaluate the postoperative outcomes of video-assisted thoracoscopic surgery (VATS)-lobectomy (VATS-L) for non-small-cell lung cancer (NSCLC) in patients with impaired lung function. The second end point was to illustrate the effective role of forced expiratory volume in 1 s (FEV1%) and the diffusing capacity of the lung for carbon monoxide (DLCO%) in predicting complications in this population. METHODS: Data from patients who underwent VATS-L at participating centres were analysed and divided into 2 groups: group A comprised patients with FEV1% and/or DLCO% >60% and group B included patients with impaired lung function defined as FEV1% and/or DLCO% ≤60%. To define clinical predictors of death and complications, we performed univariate and multivariable regression analyses. RESULTS: A total of 5562 patients underwent VATS-L, 809 (14.5%) of whom had impaired lung function. The postoperative mortality rate did not differ between the 2 groups (2.3% vs 3.2%; P = 0.77). The percentage of patients who had any complication (21.4% vs 34.2%; P ≤ 0.001), the complication rate (28% vs 49.8%; P ≤ 0.001) and the length of hospital stay (P ≤ 0.001) were higher for patients with limited pulmonary function. Impaired lung function was a strong predictor of overall and pulmonary complications at multivariable analysis. CONCLUSIONS: VATS-L for NSCLC can be performed in patients with impaired lung function without increased risk of postoperative death and with an acceptable incidence of overall and respiratory complications. Our analysis suggested that FEV1% and DLCO% play a substantial role in estimating the risk of complications after VATS-L, but their role was less reliable for estimating the mortality.

RESUMO
OBJECTIVE: The objective of the study is to analyse the causes and impact of conversion from VATS to thoracotomy identifying any possible pre-operative risk factors and related consequences. METHODS: Data from patient who underwent VATS lobectomy (VATS-L) for NSCLC at VATS Group participating centres were retrospectively analysed and divided in two groups: patients treated with VATS-L and patients who suffered from conversion. Predictors of conversion were assessed with univariate and multivariable exact logistic regression. Complications were evaluated as dependent variables of conversion in a Cox multivariable logistic regression model. RESULTS: A total of 4629 patients underwent planned VATS-L for NSCLC and of these, 432 (9.3%) required conversion; the most frequent causes were bleeding (30.4%) and fibro-calcified hilar lymph nodes (23.9%). The independent risk factors at multivariable analysis model were sex male (OR 1.458, p < 0.01), age older than 70 years (OR 1.248, p = 0.036) and the clinically node-positive disease (OR 2.258, p < 0.01). The mortality rate was similar, but the percentage of patients who suffered from any complication (41.7% vs 24.4%, p < 0.01), the complication rate (65% vs 32.2%, p < 0.01), chest tube duration (p < 0.01) and the hospitalisation rate (p < 0.01) were higher for patients converted. Atrial fibrillation (OR 1.471, p = 0.019), prolonged air leak (OR 1.403, p = 0.043), blood transfusions (OR 4.820, p < 0.01), sputum retention (OR 1.80, p = 0.027) and acute kidney failure (OR 2.758, p = 0.03) were significantly associated with conversion at multivariable analysis. CONCLUSIONS: Conversion is associated with increased surgical morbidity, blood loss and hospital stay. Sex male, old age and the clinical involvement of lymph nodes were the strongest predictors of conversion.

BACKGROUND: To evaluate the effect of first-time and eventual reiterative surgery on overall survival (OS) and disease-free survival (DFS) in Caucasian patients affected by an invasive adenocarcinoma (ADC) with at least another ground-glass opacity (GGO). METHODS: We analysed 47 patients operated on for lung ADC, identified as main cancer (MC), with at least one synchronous GGO, from January 2003 to March 2017. Characteristics associated with the evolution of GGOs were investigated with logistic regression and overall and DFS were evaluated with Kaplan-Meier method. RESULTS: Forty-two (89%) patients received an anatomic resection of the MC, 5 patients were treated by a single or multiple wedge resections. In total, 9 (19.1%) patients had all the lesions resected undergoing simultaneous resection of ipsilateral GGOs at first surgery while the remaining 38 (80.9%) patients still had at least one GGO that was followed up by serial CT scan. At the median follow-up of 41 months, GGO evolved in 16 (42.1%) patients. The presence of solid component at the initial CT scan was the only risk factor for evolution of the GGO. Thirteen patients underwent surgical resection showing an invasive ADC in 9 patients, MIA in 3 and AIS in 1. New GGOs developed in 7 (14.9%) patients, in which three underwent surgery showing the presence of solid ADC, MIA and AAH. OS rate at 5 years was 97.4%. DFS at 3 years was 82% and was significantly influenced by the stage of MC. CONCLUSIONS: Patients affected by an invasive ADC with at least another GGO nodule enjoy good OS and DFS with a surgical reiterative approach. Part-solid GGO is associated with GGO progression requiring treatment, but OS is not influenced by the new onset or evolution of GGOs. DFS is affected by the stage of the MC which dictates the treatment strategy.
RESUMO
BACKGROUND: We analyzed our experience in sternal resections (SRs) for primary or secondary neoplasm focusing on technical aspects of reconstruction, post-operative outcomes and long term survival. METHODS: From January 2005 to December 2015, 36 patients (24 males, 67%) underwent surgical excision of primary (chondrosarcoma n=18 patients, 50%; osteosarcoma n=2, 6%; Ewing sarcoma n=1, 3%; other n=2, 6%) or secondary (breast cancer n=7, 19%; kidney carcinoma n=2, 6%) sternal tumour. We performed n=30 partial sternectomy and n=6 total sternectomy with en-bloc resection of the sternocostal cartilages in all patient and extended resection in 7 patients. Stability was obtained with prosthetic material, rigid and non-rigid and a muscular flap: rigid material [Strasbourg Thoracic Osteosynthesis System (STRATOS), MedXpert GmbH] and muscle flap n=11 (30.6%); polytetrafluoroethylene patch and muscle flap n=6 (16.7%); muscle flap alone n=19 (52.8%). RESULTS: The 30-day mortality rate was 0, overall complication rate was 19%. The median ICU stay was 1.5 days and mean hospital stay was 10.6±5.9 days. We obtained a complete (R0) resection in all patients. Overall survival (OS) at 5 and 10 years were 59% and 40%; in the group of primary neoplasm OS rate at 5 and 10 years was 79% and 54%. Disease free survival (DFS) rate at 5 years was 61%. Higher grading was identified as negative prognostic factor. CONCLUSIONS: Wide radical resections of anterior chest wall are basilar in a multimodality treatment for primary or metastatic neoplasm of the sternum. Stabilization with titanium bars and clips provides rigidity of chest wall with good functional results.
RESUMO
Objectives: The surgical approach to chronic pleural empyema is still controversial. Video-assisted thoracic surgery (VATS) debridement and decortication has shown favourable outcomes, while the uniportal VATS (U-VATS) approach is still anecdotal. We report our experience with ultrasonographic (US) preoperative staging followed by U-VATS decortication for pleural empyema. Methods: We performed a retrospective analysis of patients who underwent surgical treatment of stage II and stage III pleural empyema from 2012 to 2015. Pre-, intra- and postoperative data were investigated to evaluate outcomes including postoperative complications and disease recurrence. Results were analysed according to preoperative US appearance of pleural space (stages A-E) and surgical approach (thoracotomy vs U-VATS). Results: We performed 30 (47%) uniportal thoracoscopic pleural decortication and 34 (53%) open decortication for empyema in stage II (40%) or III (60%) obtaining a complete debridement and decortication in all patients. In-hospital mortality was zero and overall morbidity was 29%. U-VATS was associated with lower blood loss (118 ± 80 ml vs 247 ± 140 ml P < 0.001), lower chest tubes duration (5.6 ± 1.4 vs 10.6 ± 4.4 days P < 0.001), shorter hospital stay (6.7 ± 1.9 vs 12.2 ± 4.7 days, P < 0.001) and lower complications (10% vs 16%, P < 0.001). Elevated US patterns (D-E) are associated with thoracotomy, higher blood loss, operative time and a significant incidence of complications. Conclusions: Uniportal thoracoscopic decortication for pleural empyema is a safe and effective approach for selected patients based on a combination of clinical and imaging staging. US patterns well corresponded with intraoperative pleural findings and showed a prognostic value.

BACKGROUND: The development of a video assisted thoracic surgery lobectomy (VATS-L) program provides a dedicated surgical team with a recognized learning curve (LC) of 50 procedures. We analyse the results of our program, comparing the LC with subsequent cases. METHODS: From June 2012 to March 2015, we performed n = 146 VATS major pulmonary resections: n = 50 (Group A: LC); n = 96 (Group B). Pre-operative mediastinal staging followed the National Comprehensive Cancer Network guidelines. All procedures were performed using a standard anterior approach to the hilum; lymphadenectomy followed the NCCN recommendations. During the LC, VATS-L indication was reserved to clinical stages I, therefore evaluated case by case. RESULTS: Mean operative time was 191 min (120-290) in Group A and 162 min (85-360) in Group B (p <0,01). Pathological T status was similar between two Groups. Lymphadenectomy included a mean of 5.8 stations in Group A and 6.6 in Group B resulting in: pN0 disease: Group A n = 44 (88 %), Group B n = 80 (83.4 %); pN1: Group A n = 3 (6 %), Group B n = 8 (8.3 %); pN2: Group A n = 3 (6 %), Group B n = 8 (8.3 %). Conversion rate was: 8 % in group A (n = 4 vascular injuries); 1.1 % in Group B (n = 1 hilar lymph node disease). We registered n = 6 (12 %) complications in Group A, n = 10 (10.6 %) in Group B. One case (1.1 %) of late post-operative mortality (90 days) was registered in Group B for liver failure. Mean hospital stay was 6.5 days in Group A and 5.9 days in Group B. CONCLUSIONS: We confirm the effectiveness of a VATS-L program with a learning curve of 50 cases performed by a dedicated surgical team. Besides the LC, conversion rate falls down, lymphadenectomy become more efficient, indications can be extended to upper stages.

INTRODUCTION: Robot-assisted minimally invasive esophagectomy with intra-thoracic anastomosis showed encouraging results but there is a lack of data to demonstrate the safety and feasibility. OBJECTIVE: The aim of this study is to report our experience in RA-ILE (robotic-assisted Ivor-Lewis esophagectomy) with robotic hand-sewn anastomosis. METHODS: This is a retrospective study of patients who underwent robotic-assisted esophagectomy in prone position with intrathoracic anastomosis for malignant neoplasm of the esophagus or esophago-gastric junction. RESULTS: From January 2012 to December 2014 we performed eight completely robot-assisted esophagectomy without intra-operative complication. The mortality rate at 30-day was zero. In two patients we observed a partial leakage of the gastric tube that required revision. The mean operative time was 499 ± 46 min including robotic set up and patient positioning. The median hospital-stay was 10 days. Complete (R0) resection was accomplished in all patients and the mean number of lymph nodes removed was 37.6 ± 14 .7. CONCLUSIONS: This preliminary experience suggests that robotic-assisted RA-ILE for malignant lesions is a real surgical option compared with conventional surgery with satisfactory results.

BACKGROUND: To assess if video-mediastinoscopy (VM) with frozen sections (FS) combined with a video-assisted thoracic surgery major pulmonary resection (VMPRS) is able to improve VATS mediastinal intraoperative staging. METHODS: From June 2012 to March 2015 a total of 146 patients underwent VMPRS lymphadenectomy. NCCN guidelines were followed for pre-operative staging, including VM with FS in 27 patients (19%). Procedural time, dissected nodal stations, complications related to VM and VATS lymphadenectomy and definitive histology, were evaluated. RESULTS: Operative time for VATS resection with VM (group 1) and VATS pulmonary resection alone (group 2) was 198±64 vs. 167±43 min (P=0.003). Mean/median numbers of dissected nodal stations were 4.93±1.1/5 (range, 4-8) in group 1 and 3.25±0.5/5 (range, 3-8) in group 2 (P<0.001). Group 1 vs. group 2 right-sided lymphadenectomy (n=86) was performed at station 2R/4R in 18 (90%) and 46 (69.7%); at station 3a/3p in 14 (51.8%) and 22 (31%); at station 7 in 18 (90%) and 44 (66.7%); at station 8/9 in 11 (55%) and 24 (36.4%) respectively. On the left side (n=60) group 1 vs. group 2 lymphadenectomy resulted at station 4 in 6 (85.7%) and 38 (71.7%); at station 5/6 in 6 (85.7%) and 26 (49%); at station 7 in 6 (85.7%) and 33 (62.3%), and at station 8/9 in 1 (14.3%) and 18 (34%). There were no early deaths and recurrent laryngeal nerve palsy occurred in 1 (0.8%) in group 2. Pathological upstaging (pN1; pN2) was found in 5 patients (17%) in group 1, and 13 (11%) in group 2 (P=0.23). About FS (n=29), formal paraffin histology resulted in 0% of both, false negative and false positive results. CONCLUSIONS: Based on our experience, the combination "VM with FS followed by VMPRS in sequence", seems to be effective and offers an alternative approach to improve intraoperative mediastinal staging.
