目的　了解近年来中低位直肠癌外科手术处理方法的变化 ,及保肛手术开展情况。方法　回顾分析我院1996～ 1998年 10 4例中低位直肠癌外科治疗情况。结果　全组根治性切除 61例 ( 5 9% ) ,保肛手术 ( 5 3 % ) ,Miles术 2 9例 ( 4 7% ) ,吻合器应用占低位直肠癌保肛手术 76% ,最低吻合距肛缘 5公分。结论　中低位直肠癌根治性切除 5 9% ,其中保肛手术占 5 3 % ,保肛手术中吻合器应用已十分普遍 ,为提高生存率和减少复发率必须注意术中无瘤操作技术 ,直肠全系膜切除技术 ,预防各种副损伤和并发症 Objective To understand the changes in surgical treatment methods for middle and low rectal cancers in recent years and the development of sphincter preservation surgery. Methods Retrospective analysis of 104 cases of low rectal cancer surgery in our hospital from 1996 to 1998. Results The total group of radical resection in 61 cases (5 9%), sphincter preserving operation (53%), Miles operation in 29 cases (47%), stapler application of low rectal cancer sphincter preservation surgery 76%, the minimum coincidence Anal margin 5 cm. Conclusions Radical resection of middle and low rectal cancer is 59%. Among them, sphincter preserving operation accounts for 5 3%. The use of stapler in sphincter preserving operation is very common. In order to improve the survival rate and reduce the recurrence rate, it is necessary to pay attention to the operation-free operation technique, rectum.
