腹腔镜直肠癌手术目前已成为临床常规术式。但与开腹手术不同，由于盆腔空间狭窄，导致无法形成满意的切割角度，以致需要多枚吻合口钉仓，这不仅增加医疗费用，同时会导致吻合口漏发生率增加。此外，由于缺乏直接的触觉感受，在狭窄盆腔内勉强闭合可能会导致远切缘不足，导致术后吻合口复发。因此，针对不同部位的直肠癌采取不同的远端闭合策略，具有重要的临床意义。

Laparoscopic surgery for rectal cancer has become a routine operation. Different from opening surgery, the narrow space of the pelvic cavity leads to the difficulty to form a satisfactory angle in placing the stapler, which leads to the need of extra anastomotic nails, increasing medical cost and incidence of anastomotic leakage. Because of lack of direct tactile sensation, closure of rectum reluctantly in the narrow pelvic cavity may lead to insufficient distal margin, resulting in postoperative anastomotic recurrence. Therefore, it is of great clinical significance to adopt different distal closure strategies according to different tumor characteristics in laparoscopic surgery for rectal cancer.
