【摘要】 目的 探讨低位直肠癌保留肛门对其预后的影响。

    方法 对25例低位直肠癌患者行术前放疗、化疗。术式：行全直肠系膜切除术(total mesorectal excision,TME),直肠分离至肛提肌水平。手术远端切缘超过肿瘤下缘1.0～2.0cm。均保留肛门。术后再给予放疗和化疗。

    结果 全组无手术死亡，无吻合口瘘和吻合口狭窄发生。大部分患者术后3～6个月大便控制良好。随访1～37个月，仅有1例复发，1例死于心脏病。

    结论 对于低位直肠癌患者，配合术前术后放、化疗，采用TME手术，不仅可以保留患者肛门，避免了人造肛门所致的心理影响，而且同样可以取得较好疗效。
