No-drain management after thoracoscopic lung wedge resection with a novel intraoperative sealing test.

Objective: Although previous studies have reported the safety of no-drain management after thoracoscopic wedge resection, most of those studies were non-inferiority trials. The aim of this study was to evaluate whether no-drain management with an optimal sealing test affects post-operative complications in patients after thoracoscopic wedge resection.

Methods: A total of 906 patients who underwent thoracoscopic lung wedge resection for various disorders except secondary pneumothorax between 2011 and 2020 were analyzed.
