Abstract: ObjectiveTo analysis the advanges of singleport video assisted thoracoscopic surgery(VATS) compared to three portVATS in the lung cancer patitens. MethodsRetrospective analysis of clinical data of 137 patients with lung cancer were performed. Among the patients，65 cases undertook  singleport VATS surgery were observation group, and 72 cases received three ports VATS were control group. The operation time，blood loss, postoperative drainage amount, chest tube drainage duration，postoperative hospital stay, the Visual Analogue Scale(VAS) score pain score of the 1st and 2nd postoperative day,shoulder disfunction,the incision discomfort in the 30th and 90th postoperative day, and the incision satisfaction degree were evaluated between the two groups. ResultsAll the patients were underwent total VATS surgery successfully and no severe complications were observed. There were no significant difference on  blood loss, postoperative drainage amount，chest tube drainage duration，postoperativep hospital day(P＞005) between the two groups．Compared to control group，renees in operation time was longer(P＜005), the VAS score of the 1st and 2nd postoperative day was lower(P＜005), the incision discomfort of 30th and 90th postoperative day was reduced and the incision satisfaetion degree was significantly improved(P＜005), shoulder disfunction  rate was lower(P＜005) in observation group. ConclusionSingleport VATS surgery had the same result cmopared with the three ports VATS, but the postoperative recovery is more better in singleport VATS surgery, which indicated singleport VATS surgery is worthy of clinical promotion.
