Closed Versus Open Vent Port Techniques and the Disconnection Technique for Optimizing Lung Collapse With Bronchial Blockers in Video-Assisted Thoracoscopic Surgery: A Randomized Controlled Trial

Introduction

For patients undergoing video-assisted thoracoscopic surgery (VATS) for lung cancer or other pulmonary lesions, effective one-lung ventilation (OLV) is essential to provide surgical exposure. Bronchial blockers (BBs) are increasingly used for OLV, but the optimal management of their vent port to accelerate lung collapse remains unclear.
