目的 :探讨低位直肠癌保肛手术方法及其吻合技术。方法 :报告 5 5例低位直肠癌保肛手术的近期疗效、并发症。结果 :在根治性切除的基础上 ,5 1例采用单吻合器行端端吻合无并发症 ;2例采用双吻合器行端侧吻合 ,均发生吻合口瘘 ;2例采用仿 Mounsell- weir吻合效果良好。结论 :1肿瘤下缘距肛缘 5～ 7cm,侵及肠壁周径≤ 1/2 ,无远处转移 ,且术中游离超过肿瘤下缘 2～ 3cm者 ,均可先用保肛手术 ;2采用荷包缝合钳加单吻合器的端端吻合是理想的吻合方法
Objective: To study the anus-preserving surgery and its anastomosis technique in low rectal cancer. Methods: To report the short-term curative effect and complications of 55 cases of rectal cancer with anus preservation. Results: On the basis of radical resection, 51 patients underwent single stapling without end-to-end anastomosis without complications; 2 patients underwent end-to-end anastomosis with double stapling, anastomotic fistula occurred and 2 patients underwent Mounsell-weir anastomosis Good effect. Conclusions: 1 The lower margin of tumor from anal margin 5 ~ 7cm, invasion and intestinal wall circumference ≤ 1/2, no distant metastasis, and surgery free margin than the lower edge of 2 ~ 3cm those who can use anal sphincter surgery; 2 pouch suture with a single stapler end anastomosis is the ideal method of anastomosis
