Abstract： 目的探讨低位Ⅰ期直肠癌的外科治疗效果及影响复发和预后的因素.方法回顾性分析166例低位Ⅰ期直肠癌患者的临床资料.结果本组根治性手术138例,均按直肠全系膜切除(TME)手术原则进行;其中93例行腹会阴联合根治术,45例行保肛手术;肿瘤局部切除术28例.局部复发率根治性手术者为5.1%(7/138),其中腹会阴联合根治术组为6.5%(6/93),保肛术组为2.2%(1/45);局部切除术组为17.9%(5/28).χ2检验显示,肿瘤分化程度(P=0.009)和手术方式(P=0.039)与局部复发相关.腹会阴联合根治术组5年生存率为90.4%,保肛术组为95.5%,局部切除术组为82.6%.单因素分析显示,肿瘤分化程度(P=0.000)和局部复发(P=0.000)与预后相关;多因素分析显示,局部复发是影响预后的主要因素(P=0.000).结论低位Ⅰ期直肠癌根治性手术切除复发率低、预后好.局部切除术的选择应严格把握指征.
