Background It has been reported that tubeless video-assisted thoracoscopic surgery (tubeless-VATS) is feasible and safe for thoracic diseases. Herein, we compared the early outcomes of mediastinal lesion resection between the tubeless and traditional VATS. Methods Clinical data of all patients who underwent thoracoscopic mediastinal tumor resection were retrospectively collected. The study involved two groups: tubeless and traditional VATS group. Propensity score matching (PSM) was applied to eliminate the population bias. Intraoperative and postoperative variables were compared among matched cohorts. Results In total, 43 patients in the tubeless group and 231 patients in the traditional VATS group were included. After 1:1 PSM, baseline characteristics were comparable. Anesthesia time (177.63 vs. 202.53 min; P=0.004) was shorter in tubeless group, while operation time (90.95 vs. 101.47 min; P=0.109) was similar. Overall, the total postoperative morbidity rate was similar in the two groups (15% vs. 12.5%; P=0.556). Specially, 4/43 patients in tubeless VATS group need to be re-put chest tubes postoperatively. A significant lower similar level of visual analogue scale score was observed in tubeless VATS group (1.73±0.48 vs. 3.41±0.87, P<0.001) in postoperative day 1. Meanwhile, the number of patients using postoperative opioid analgesia was also lower in tubeless VATS group (22.88% vs. 48.38%, P=0.016). Furthermore, hospital duration after surgery (2.58 vs. 5.47 days; P=0.002) was shorter in tubeless group. Conclusions Compared with traditional VATS, tubeless VATS for mediastinal tumor may shorten the anesthesia time, decrease postoperative pain and fasten postoperative recovery in carefully selected patients.
