Background Air leak is the most common complication after lung resection and leads to increased length of hospital (LOH) stay or patient discharge with a chest tube. Management by autologous blood patch pleurodesis (ABPP) is controversial because few studies exist, and the technique has yet to be standardized. Methods We retrospectively reviewed patients undergoing ABPP for prolonged air leak (PAL) following lobectomy in three centers, between January 2014 and December 2019. They were divided into two groups: Group A, 120 mL of blood infused; Group B, 60 mL. Propensity score-matched (PSM) analysis was performed, and 23 patients were included in each group. Numbers and success rates of blood patch, time to cessation of air leak, time to chest tube removal, reoperation, LOH, and complications were examined. Univariate and multivariate analysis of variables associated with an increased risk of air leak was performed. Results After the PSM, 120 mL of blood is statistically significant in reducing the number of days before chest tube removal after ABPP (2.78 vs. 4.35), LOH after ABPP (3.78 vs. 10.00), and LOH (8.78 vs. 15.17). Complications (0 vs. 4) and hours until air leak cessation (6.83 vs. 3.91, range 1–13) after ABPP were also statistically different (p < 0.05). Air leaks that persisted for up to 13 hours required another ABPP. No patient had re-operation or long-term complications related to pleurodesis. Conclusion In our experience, 120 mL is the optimal amount of blood and the procedure can be repeated every 24 hours with the chest tube clamped. [ABSTRACT FROM AUTHOR]

The surgical treatment of advanced non-small-cell-lung-cancer (NSCLC) invading mediastinal organs and great vessels is still controversial. The aim of this multicentre study is to analyse oncological outcomes, surgical outcomes and prognostic factors of patients with NSCLC involving heart and great vessels. 362 patients treated surgically for locally advanced T4-NCSLC between 1990 and 2020 were retrospectively reviewed. Patients were divided into five subgroups: pulmonary artery(n = 129), left atrium(n = 82), superior vena cava(n = 80), aorta(n = 43), and multiple vascular structures(n = 28). Resection was complete in 327(90%) patients. Overall 90-day mortality was 8.8%, influenced by poly-transfusions, pneumonectomy, bronchopleural fistula and previous cardiovascular disease (4.5HR.p = 0.03, 3.7HR p = 0.01, 14.0HR.p < 0.001 and 3.0HR p < 0.01). One-, 3- and 5-year survival rates were 75%, 43%, 33%, respectively and there were significant differences among the five groups(p < 0.001). Survival was significantly affected by induction radiotherapy, nodal status, pTNM-stage and radicality (3.8HR p = 0.03, 2.6HR p = 0.001, 1.6HR p < 0.05 and 1.6HR p < 0.05). Surgery provided acceptable results in selected patients with T4-NSCLC with major vascular infiltration in expert centres. Nodal-status and radicality influenced the overall-survival and disease-free survival. Neoadjuvant chemotherapy appears to have a positive effect on long-term results, particularly in N2-patients.

Bronchoplastic procedures have become the reference standard in the lung parenchyma-sparing treatment of centrally located bronchopulmonary tumors. Two schools of thought exist regarding performing a bronchial sleeve resection: those who wrap the anastomosis with a pedicled flap and those who leave the anastomosis unprotected. We performed a study comparing these 2 methods. This study was a retrospective multicenter observational analysis of 90 consecutive patients undergoing bronchial sleeve resections for neoplastic disease between June 2009 and July 2019. Group A (60 patients) underwent bronchial wrapping and group B (30 patients) did not undergo wrapping. The only difference between group A, which had 5 patients (8.3%), and group B, which had 10 patients (33.3%), regarding general characteristics was the presence of diabetes (P =.003). There were no differences in surgical, postoperative, and follow-up characteristics. There was no statistically significant difference between groups (group A, 9 patients [15%]; and group B, 6 patients [20%]) in terms of anastomotic complications at 1 year (P =.425). Diabetes was an independent predictive factor for anastomotic complications at 1 year (P =.035). The number of postoperative complications (P <.001) was an independent risk factor for length of hospital stay. We found no differences between groups in terms of postoperative complications and length of hospital stay, which confirmed previous reports that sleeve resections may be performed safely without bronchial wrapping.
