目的探讨低位直肠癌行保肛手术的临床意义。方法对我院1998年～2003年57例距肛缘7cm以下的行保肛的直肠癌根治术的病人进行回顾性分析。所有病例均使用吻合器进行肠吻合。结果局部复发率为7.8%,直肠癌行保肛术术后并发症明显减少,生存质量明显提高。结论由于吻合器的广泛使用,保肛指征较前明显放宽,术后患者生活质量有了明显提高。 Objective To investigate the clinical significance of sphincter preserving surgery in low rectal cancer. Methods Retrospective analysis was performed on 57 cases of rectal cancer undergoing anal sphincter preservation in our hospital from 1998 to 2003, which ranged from 7cm below the anal verge. All cases were anastomosed for intestinal anastomosis. Results The local recurrence rate was 7.8%. The safety of rectal cancer was significantly reduced after operation and the quality of life was significantly improved. Conclusion Due to the extensive use of stapler, the anus-retention indications were obviously relaxed compared with those before, and the quality of life of postoperative patients was significantly improved.
