目的：评估三孔法腹腔镜胃袖状切除术（laparoscopic sleeve gastrectomy，LSG）的可行性、安全性和手术疗效。方法：回顾性分析2020年4月至2021年1月间130例行LSG并按时完成随访的肥胖病人临床资料，按手术方式分组，三孔法组52例，四孔法组78例。比较两组围术期情况及术后减重效果。结果：两组均顺利完成LSG，与四孔法组相比，三孔法组平均手术时间更短[(88.35±22.64) min比(98.29±26.25) min，P=0.027），两组术中出血量、术后疼痛、术后引流量、术后住院时间、术后并发症发生情况、术后6个月及2年的减重效果差异均无统计学意义（均P>0.05）。结论：三孔法LSG在不增加手术并发症及手术时间的前提下，可以减少病人手术瘢痕的数量和大小，有利于术后皮肤美观，并获得与四孔法LSG相同的减重疗效，可以作为胃袖状切除术的常规术式。

Objective To evaluate the feasibility, safety and efficacy of three-port laparoscopic sleeve gastrectomy(LSG). Methods Clinical data of 130 patients with obesity who underwent LSG from April 2020 to January 2021 and completed follow-up in time were analyzed retrospectively. All patients were divided into two groups as surgical method, there were 52 cases in three-port group and 78 cases in four-port group. Perioperative indicators and improvement of obesity in two groups were compared. Results All procedures were performed via LSG. Compared with four-port group, the mean operative time of three-port group was shorter [(88.35±22.64) min vs. (98.29±26.25) min, P=0.027]. There were no significant differences in amount of bleeding intraoperative, postoperative pain, postoperative drainage, hospital stay after operation, postoperative complication rate and weight loss 6 months and 2 years after surgery (P>0.05). Conclusions Under the premise of no increase in surgical complications and operative time, three-port LSG can reduce the number and size of surgical scars, which is conducive to skin beauty, and obtain the same weight loss effect as four-port LSG, and can be used as a routine operation for sleeve gastrectomy.
