摘要
目的探讨直肠癌低位保肛手术指征及手术要点。方法回顾性分析我科2002年1月至2007年3月应用消化道吻合器治疗23例低位直肠癌的临床资料。结果全组无手术死亡、无手术并发症，随访至今无复发。结论我们认为直肠癌低位手术保肛的指征是：①直肠肿瘤下缘距肛缘超过5cm；②早期直肠癌局限于肠壁内，其直径小于3em；③进展期癌侵犯肠壁周径小于1／2，未侵肠壁浆膜层以及累及其周围组织、器官；④乳头状腺瘤恶变，或分化度为Ⅰ-Ⅱ级腺癌。手术要完全依从肿瘤根治、淋巴结清扫的规范，下切缘在肿瘤下方2—3cm，上切缘在乙状结肠的中上段，淋巴结清扫包括乙状结肠、直肠系膜区域的淋巴结及两侧闭孔淋巴结，方可大大改善预后及提高术后生活质量。
Objective To analyze surgical indications and methods for keeping anus operation in treating patients with middle - lower segment rectum cancer.
