Surgical resection for congenital lung malformation: Lessons learned from thoracotomy to biportal thoracoscopy under one-lung ventilation

Background: The purpose of this study is to compare the clinical characteristics and surgical outcomes of thoracotomy and video-assisted thoracoscopic surgery (VATS) in children with congenital lung malformations (CLMs) in a tertiary referring center and to report our modified biportal VATS setting.Methods: This is a single-center retrospective chart review study including children who under-went surgical resection for CLMs between January 2007 and December 2020. Patient character-istics and surgical outcomes were compared between open and thoracoscopy, as well as conventional VATS and biportal VATS. Biportal setting included an anterior utility wound and a camera trocar wound with one-lung ventilation.Results: A total of 100 patients were identified. Twenty patients received thoracotomy, and 80 patients received VATS (67 conventional and 13 biportal VATS). The median age at operation
