腹部无辅助切口腹腔镜直肠癌根治术的应用体会

目的：探讨腹部无辅助切口腹腔镜直肠癌根治术的可行性。方法回顾性分析2011年1月至2013年6月间在河南大学淮河医院接受改良法腹部无辅助切口腹腔镜直肠癌根治术的26例患者的临床资料。按全直肠系膜切除理念清扫淋巴结和游离结直肠后，在距肿瘤远侧2 cm处以直线切割闭合器切断闭合肠管，组织钳夹将游离的远端直肠经肛门外翻拖出后敞开，标本经保护套从肛门拖出，体外切除标本后在腹腔镜引导下完成吻合。结果26例患者手术均获成功。手术时间（126±35） min，术中出血（33±61） ml，清扫淋巴结（17.0±5．6）枚，术后排气时间（2．7±1．3） d，术后住院时间（7．9±2．6） d，术后发生吻合口出血1例。结论腹部无辅助切口腹腔镜直肠癌根治术安全可行。

Experiences of scarless laparoscopic radical resection of rectal cancer

Objective To explore the feasibility and safety of scarless laparoscopic radical resection of rectal cancer. Methods Clinical data of 26 patients who underwent scarless laparoscopic radical resection of rectal cancer from January 2011 to June 2013 were retrospectively analyzed. Lymph node dissection and transection of proximal and distal colon were performed in the conventional manner of total mesorectal excision（TME）. The distal rectum 2 cm away from the tumor was closed with a linear stapler, and was pulled out through the anus. The specimen was extracted through the Alexis. The rectal opening was reclosed with a linear stapler. End-to-end colorectal anastomosis was performed using the double-stapling technique. Results The operation time was （126 ±35） min. The intraoperative blood loss was （33 ±61） ml. The number of harvested lymph nodes was 17.0 ±5.6. The time to first bowel movement was （2.7±1.3） d. The postoperative hospital stay was （7.9±2.6） d. Only one case developed anastomotic hemorrhage. Conclusion Scarless laparoscopic radical resection of rectal cancer is feasible.
