单切口腹腔镜在各种微创手术技术中占有重要地位。为记录比较单切口腹腔镜和传统腹腔镜结肠切除术围手术期结果和中期肿瘤学结果,Yun JA等纳入了2010~2011年期间对原发性结肠癌进行结肠根治切除术的767例患者(250为单切口腹腔镜,517例为传统腹腔镜),采用倾向得分配比方法进行分组。配比前,传统腹腔镜患者并存病比例显著较高;配比后,每组239例患者,单切口腹腔镜组的预计失血量高于传统腹腔镜组,术后随访中位数为37个月,单切口腹腔镜组和传统腹腔镜 Single-incision laparoscopy in a variety of minimally invasive surgical techniques occupy an important position. To document the perioperative and metaphase oncologic outcomes of single versus conventional laparoscopic colectomy, Yun JA et al. Enrolled 767 patients undergoing radical mastectomy for primary colon cancer between 2010 and 2011 ( 250 for single-incision laparoscopy, 517 cases for the traditional laparoscopic), using propensity score method for grouping. Before the ratio, the proportion of patients with conventional laparoscopic comorbidities was significantly higher; the ratio of 239 patients per group, the single-incision laparoscopic group expected blood loss was higher than the traditional laparoscopic group, the median postoperative follow-up was 37 Month, single incision laparoscopic group and traditional laparoscopy
