The vessel-depleted neck situation is a challenge for the surgeon in search of suitable recipient vessels for microvascular reconstruction of the head and neck. The internal thoracic vessels (ITVs) have proven useful as "rescue" recipient vessel resource. The objective of this report is to assess the feasibility of using ITVs by rerouting the pedicle for free flap reconstruction of the head and neck by comparing two different approaches.Two surgical approaches were assessed: the classical one is parasternal, but cardiac surgeons commonly use median sternotomy. We conducted an anatomical study, comparing on the same subject the lengths and diameters of both internal thoracic artery (ITA) and internal thoracic vein (ITV) at the sixth, fifth, and fourth intercostal spaces (ICSs) through parasternal approach on one side and by median sternotomy on the other side.The study was performed on 13 subjects. We found a superiority of length of the ITVs with the median sternotomy approach. Regarding the mean length of the ITA, the sternotomy approach allowed a significant greater length with 119/89/67 mm, compared with parasternal approach with 91/62/42 mm, respectively at the sixth, fifth, and fourth ICS (p0.001). Similarly, we observed a significant greater length of the ITV with 116/85/63 mm versus 89/62/42 mm (p0.001). The mean arterial and venous diameters were 2.9 mm and 2.1 mm in the sixth ICS, 3.3 mm and 2.3 mm in the fifth ICS, and 3.9 mm and 2.9 mm in the fourth ICS, respectively.These results help to guide the choice of surgical approach and the level of harvesting.

Importance: Ninety-day mortality rates after esophagectomy are an indicator of the quality of surgical oncologic management. Accurate risk prediction based on large data sets may aid patients and surgeons in making informed decisions. Objective: To develop and validate a risk prediction model of death within 90 days after esophagectomy for cancer using the International Esodata Study Group (IESG) database, the largest existing prospective, multicenter cohort reporting standardized postoperative outcomes. Design, Setting, and Participants: In this diagnostic/prognostic study, we performed a retrospective analysis of patients from 39 institutions in 19 countries between January 1, 2015, and December 31, 2019. Patients with esophageal cancer were randomly assigned to development and validation cohorts. A scoring system that predicted death within 90 days based on logistic regression ß coefficients was conducted. A final prognostic score was determined and categorized into homogeneous risk groups that predicted death within 90 days. Calibration and discrimination tests were assessed between cohorts. Exposures: Esophageal resection for cancer of the esophagus and gastroesophageal junction. Main Outcomes and Measures: All-cause postoperative 90-day mortality. Results: A total of 8403 patients (mean [SD] age, 63.6 [9.0] years; 6641 [79.0%] male) were included. The 30-day mortality rate was 2.0% (n = 164), and the 90-day mortality rate was 4.2% (n = 353). Development (n = 4172) and validation (n = 4231) cohorts were randomly assigned. The multiple logistic regression model identified 10 weighted point variables factored into the prognostic score: age, sex, body mass index, performance status, myocardial infarction, connective tissue disease, peripheral vascular disease, liver disease, neoadjuvant treatment, and hospital volume. The prognostic scores were categorized into 5 risk groups: very low risk (score, =1; 90-day mortality, 1.8%), low risk (score, 0; 90-day mortality, 3.0%), medium risk (score, -1 to -2; 90-day mortality, 5.8%), high risk (score, -3 to -4: 90-day mortality, 8.9%), and very high risk (score, =-5; 90-day mortality, 18.2%). The model was supported by nonsignificance in the Hosmer-Lemeshow test. The discrimination (area under the receiver operating characteristic curve) was 0.68 (95% CI, 0.64-0.72) in the development cohort and 0.64 (95% CI, 0.60-0.69) in the validation cohort. Conclusions and Relevance: In this study, on the basis of preoperative variables, the IESG risk prediction model allowed stratification of an individual patient's risk of death within 90 days after esophagectomy. These data suggest that this model can help in the decision-making process when esophageal cancer surgery is being considered and in informed consent.

OBJECTIVES Our goal was to evaluate the association between the distance of the tumour to the visceral pleura and the rate of local recurrence in patients surgically treated for stage pI lung cancer. METHODS We conducted a single-centre retrospective review of 578 consecutive patients with clinical stage IA lung cancer who underwent a lobectomy or segmentectomy from January 2010 to December 2019. We excluded 107 patients with positive margins, previous lung cancer, neoadjuvant treatment and pathological stage II or higher status or for whom preoperative computed tomography (CT) scans were not available at the time of the study. The distance between the tumour and the closest visceral pleura area (fissure/mediastinum/lateral) was assessed by 2 independent investigators who used preoperative CT scans and multiplanar 3-dimensional reconstructions. An area under the receiver operating characteristic curve analysis was performed to determine the best threshold for the tumour/pleura distance. Then multivariable survival analyses were used to assess the relationship between local recurrence and this threshold in relation to other variables. RESULTS Local recurrence occurred in 27/471 patients (5.8%). A cut-off value of 5 mm between the tumour and the pleura was determined statistically. In the multivariable analysis, the local recurrence rate was significantly higher in patients with a tumour-to-pleura distance ≤5 mm compared to patients with a tumour-to-pleura distance >5 mm (8.5% vs 2.7%, hazard ratio 3.36, 95% confidence interval: 1.31–8.59, P = 0.012). Subgroup analyses of patients with pIA and tumour size ≤2 cm identified local recurrences in 4/78 patients treated with segmentectomy (5.1%), with a significantly higher occurrence with tumour-to-pleura distances ≤5 mm (11.4% vs 0%, P = 0.037), and in 16/292 patients treated with lobectomy (5.5%) without significant higher occurrence in tumour-to-pleura distances of ≤5 mm (7.7% vs 3.4%, P = 0.13). CONCLUSIONS The peripheral location of a lung tumour is associated with a higher rate of local recurrence and should be taken into account during preoperative planning when considering segmental versus lobar resection.

OBJECTIVES The aim of this study was to describe the epidemiology of patients undergoing diagnostic and/or curative surgical pulmonary resections for lung opacities suspected of being localized primary lung cancers without preoperative tissue confirmation. METHODS We performed a single-centre retrospective study of a prospectively implemented institutional database of all patients who underwent pulmonary resection between January 2010 and December 2020. Patients were selected when surgery complied with the Fleischner society guidelines. We performed a multivariable logistic regression to determine the preoperative variables associated with malignancy. RESULTS Among 1392 patients, 213 (15.3%) had a final diagnosis of benignancy. We quantified futile parenchymal resections in 29 (2.1%) patients defined by an anatomical resection of >2 lung segments for benign lesions that did not modified the clinical management. Compared with patients with malignancies, patients with benignancies were younger (57.5 vs 63.9 years, P CONCLUSIONS Futile parenchymal lung resection for suspicious opacities without preoperative tissue diagnosis is rare (2.1%) while surgery for benign lesions represented 15.3% and has a satisfactory safety profile with very low postoperative morbi-mortality.

OBJECTIVES The aim of this study was to assess the long-term outcomes of patients treated by anatomical pulmonary resection with the video-assisted thoracoscopic surgery (VATS) approach, VATS requiring intraoperative conversion to thoracotomy or an upfront open thoracotomy for lung cancer surgery. METHODS We performed a retrospective single-centre study that included consecutive patients between January 2011 and December 2018 treated either by VATS (with or without intraoperative conversion) or open thoracotomy for non-small-cell lung cancer (NSCLC). Patients treated for a benign or metastatic condition, stage IV disease, multiple primary lung cancer or by resection, such as pneumonectomies or angioplastic/bronchoplastic/chest wall resections, were excluded. RESULTS Among 1431 patients, 846 were included: 439 who underwent full-VATS, 94 who underwent VATS-conversion (21 emergent, 73 non-emergent) and 313 treated with upfront open thoracotomy. The median follow-up was 37 months. There were no statistical differences in stage-specific overall survival between the full-VATS, VATS-conversion, and open thoracotomy groups, with 5-year OS for stage I NSCLC of 76%, 72.3% and 69.4%, respectively (P = 0.47). There was a difference in disease-free survival for stage I NSCLC, with 71%, 60.2% and 53%, respectively at 5 years (P = 0.013). Fewer complications occurred in the full-VATS group (pneumonia, arrhythmia, length of stay), but complication rates were similar between the VATS-conversion and thoracotomy groups. CONCLUSIONS VATS resection for NSCLC with intraoperative conversion does not appear to alter the long-term oncological outcome relative to full-VATS or open upfront thoracotomy. Postoperative complications were higher than for full-VATS and comparable to those for thoracotomy. VATS should be favoured when possible.

OBJECTIVES Intraoperative conversion from video-assisted thoracic surgery (VATS) to thoracotomy may occur during anatomical lung resection. The objectives of the present study were to identify risk factors for intraoperative conversion and to develop a predictive score. METHODS We performed a multicentre retrospective analysis of French thoracic surgery departments that contributed data on anatomical lung resections to the Epithor database over a 10-year period (from January-2010 to December-2019). Using univariate and multivariate logistic regression analyses, we determined risk factors for intraoperative conversion and elaborated the Epithor conversion score (ECS). The ECS was then validated in a cohort of patients operated on between January- and June-2020. RESULTS From January-2010 to December-2019, 210,037 patients had been registered in the Epithor database. Of these, 55,030 had undergone anatomical lung resection. We excluded patients who had upfront a thoracotomy or robotic-assisted thoracoscopic surgery (n = 40,293) and those with missing data (6,794). Hence, 7943 patients with intent-to-treat VATS were assessed: 7100 with a full VATS procedure and 843 patients with intraoperative conversion to thoracotomy (conversion rate: 10.6%). Thirteen potential risk factors were identified among patients’ preoperative characteristics and planned surgical procedures and were weighted accordingly to give the ECS. The score showed acceptable discriminatory power (area under the curve: 0.62 in the development cohort and 0.64 in the validation cohort) and good calibration (P = 0.23 in the development cohort and 0.30 in the validation cohort). CONCLUSIONS Thirteen potential preoperative risk factors were identified, enabling us to develop and validate the ECS—an easy-to-use, reproducible tool for estimating the risk of intraoperative conversion during VATS.

Riassunto Le fistole eso-tracheo-bronchiali benigne acquisite dell’adulto sono situazioni cliniche rare, ma sempre complesse. Questa patologia si verifica, il piu delle volte, in pazienti debilitati da un lungo ricovero in terapia intensiva e associa una contaminazione cronica dell’albero bronchiale a una grave malnutrizione. La strategia terapeutica e multidisciplinare e combina il trattamento medico con una gestione endoscopica e chirurgica. Deve concentrarsi sulla definizione del momento ottimale per la riparazione chirurgica, mentre la tecnica utilizzata dipendera dalla sede della fistola. Se si deve privilegiare la riparazione ideale, a volte puo essere necessaria l’esclusione temporanea o definitiva del tubo digerente. Dopo un breve richiamo fisiopatologico ed eziologico, la strategia terapeutica viene descritta in dettaglio e illustrata con l’ausilio di foto e video.

Background Patients treated surgically for lung cancer may present synchronous or metachronous lung cancers. The aim of this study was to evaluate outcomes after a second contralateral anatomic surgical resection for lung cancer. Methods We performed a retrospective two-center study, based on a prospective indexed database. Included patients were treated surgically by bilateral anatomic surgical resection for a second primary lung cancer. We excluded nonanatomic resections, benign lesions, and ipsilateral second surgical resections. Results Between January 2011 and September 2018, 55 patients underwent contralateral anatomic surgical resections for lung cancer, mostly for metachronous cancers. The first surgical resection was a lobectomy in most cases (45 lobectomies: 81.8%, 9 segmentectomies: 16.4%, and 1 bilobectomy: 1.8%), and a video-assisted thoracic surgery (VATS) procedure was used in 23 cases (41.8%). The mean interval between the operations was 38 months, and lobectomy was less frequent for the second surgical resection (35 lobectomies: 63.6% and 20 segmentectomies: 36.4%), with VATS procedures performed in 41 cases (74.5%). Ninety-day mortality was 10.9% (n = 6), and 3-year survival was 77%. Risk factor analysis identified the number of resected segments during the second intervention or the total number of resected segments, extent of resection (lobectomy vs. segmentectomy), surgical approach (thoracotomy vs. VATS), tumor stage, and nodal involvement as potential prognostic factors for long-term survival. Conclusion A second contralateral anatomic surgical resection for multiple primary lung cancer is possible, with a higher early mortality rate, but acceptable long-term survival, and should be indicated for carefully selected patients.
