低位直肠癌保肛手术临床观察(附48例报告)

目的 探讨低位直肠癌保肛手术的治疗效果.方法 对48例低位直肠癌(肿瘤下界距肛缘4～7cm)患者采用双吻合器行保肛手术治疗(保肛组),其中2例为多发癌,6例合并肠梗阻,对前期60例直肠癌行Miles术(Miles组),比较2组患者术后3年生存率、局部复发率、排便功能和控便能力.结果 保肛组和Miles组术后局部复发率分别为8.33%和8.33%,3年生存率分别为87.5%和88.3%,2组比较差异无显著性(P>0.05);1年后2组患者大便次数均明显减少,差异无显著性(P>0.05);Miles组术后丧失控便能力,而保肛组的控便能力逐渐好转,12个月时已无患者存在大便失禁,明显优于Miles组(P<0.05).结论 对于距肛缘4～7 cm之间的低位直肠癌,行保肛术是合理可行的,可获得与Miles术相似的近期疗效,且具有更好控便能力.多发癌或并发结肠梗阻、不是保肛手术禁忌症.

Analysis of 48 cases of anal sphincter preserving operation for low rectal carcinoma

Objective] To explore the curative effects of anal sphincter preserving operation for low rectal carcinoma. Methods] 48 cases of low rectal carcinoma between 4~7 cm from anal verge were underwent anal sphincter preserving operation using double stap ling device (ASPO group), 2 of them were multiple synchronous cancer and 6 patients have acute colon obstruction. 60 cases of rectal carcinoma between 2~7 cm from anal verge were underwent Miles operation (Miles group). Analysis was conducted on three-year sur...
