Background: Postoperative bronchial anastomotic complications are not uncommon in lung transplant recipients. We investigated 2 surgical techniques (continuous and interrupted sutures) during bronchial anastomosis, comparing survival and postoperative bronchial complications. Methods: We retrospectively analyzed 421 patients who were transplanted in our center (February 2012 to March 2018). Patients were divided according to bronchial anastomotic technique (continuous or interrupted). Demographics and clinical parameters were compared for significance (P < .05). Comparison of postoperative morbidity included bronchial complications, venovenous extracorporeal membrane oxygenation support, and intervention requirements. Survival was assessed using Kaplan-Meier curve and log-rank tests (P < .05). Results: Of the 421 patients, 290 underwent bronchial anastomoses with continuous suture; 44 of these patients had postoperative bronchial complications (15.2%). Contrarily, 131 patients underwent the interrupted suture technique; 9 patients in this group had postoperative bronchial complications (6.9%). Demographics and clinical parameters included age, sex, ethnicity, etiology, lung allocation score, body mass index, donor age, lung transplant type, cardiopulmonary bypass usage, surgical approaches, and median length of stay. Postoperative complications (continuous vs interrupted) were bronchial complications (P = .017), venovenous extracorporeal membrane oxygenation support (P = .41), venoarterial extracorporeal membrane oxygenation support (P = .38), and complications requiring dilatation with stent placement (P = .09). Kaplan-Meier curve showed better survival in the interrupted group (P = .0002). Conclusions: Our study demonstrated the comparable postoperative results between the continuous and interrupted technique.
