The Effect of a Combined Drainage Strategy in Uniportal Upper Lung Lobectomy

Traditional drainage for uniportal video assisted thoracoscopic surgery (VATS) is a routine method, usually with one or two chest tubes at intercostal incisions, but postoperative pain due to the chest tube and unsatisfied drainage effect was noted. In this study, the investigators are going to explore whether a prophylactic air-extraction catheter combined with chest tube drainage may not increase complications in uniportal VATS for upper lung lobectomy. The patients would be assigned to two arms, one with a prophylactic air-extraction catheter combined with chest tube, and another with two chest tubes, and the effect of the combined drainage strategy will be evaluated.
