Simultaneous bilateral thoracoscopic lobectomy for synchronous bilateral multiple primary lung cancer-single center experience

Background: The aim of this study was to investigate the feasibility and safety of simultaneous bilateral thoracoscopic lobectomy and compare perioperative and late outcomes between simultaneous and staged bilateral thoracoscopic lobectomy. Methods: Between January 2013 and December 2017, the medical records of patients who underwent bilateral thoracoscopic lobectomy for synchronous bilateral multiple primary lung cancer (SPLC) were reviewed retrospectively. Univariate analysis was used to examine the factors associated with morbidity. Survival was estimated with the Kaplan-Meier method. Results: In the simultaneous resection group (n=41) and the staged groups (n=66), 11 and 16 patients underwent postoperative complication, respectively, whereas no significant differences existed between two groups (P=0.850). Univariate analysis showed that preoperative comorbidities (P=0.009), FEV1
