Uniportal video-assisted thoracoscopic complex and simple segmentectomy for treating early-stage non-small cell lung cancer
Abstract
Our study intends to investigate the feasibility and safety of uniportal video-assisted thoracoscopic complex and simple segmentectomy in treating early non-small cell lung cancer (NSCLC). We retrospectively selected 136 early NSCLC patients from January 2018 to July 2019. There were 61 patients receiving uniportal video-assisted thoracoscopic surgery (U-VATS) who were then assigned into simple segmentectomy group (SS) (n=15) and complex segmentectomy group (CS) (n=46) according to the number and shape of intersegmental plane. 75 patients undergoing U-VATS lobectomy (LT) during the same time were selected as control group. The operative and postoperative outcomes were evaluated. No differences were found regarding age, sex, smoking history among the three groups. Tumor size in segmentectomy group was significantly reduced compared to lobectomy (P<0.01). The operative time of SS group was significantly decreased compared with S group and LT group (P<0.01). Both SS and CS groups could acquire appropriate surgical margins. While lymph nodes number dissected in LT group was significantly increased compared to segmentectomy group (P<0.01). No differences of postoperative complications, tube duration, drainage volume and postoperative stay were observed among three groups. However, FEV1 (L), FVC (L) and MVV (L/min) in segmentectomy group and lobectomy group were significantly decreased at one month after surgery with more improvement in segmentectomy than lobectomy (P<0.05). In conclusion, U-VATS and simple segmentectomy is safe and feasible to treat early NSCLC in short term.
