[摘要]目的 明确盆腔内直肠与直肠周围组织结构之间的解剖毗邻关系，为合理化手术平面的设计奠定基础。方法 断层解剖1例尸体骨盆，观察不同层面上直肠与周围脏器关系。结果 直肠、直肠系膜与周围的组织结构如膀胱、前列腺、精囊腺以及盆自主神经等都存在着明确的组织间隙。结论 直肠癌手术时只要沿着正确的手术层面进行，不但能够降低局部的复发率，而且能够最大限度地改善病人手术后的生活质量。

    [ABSTRACT]ObjectiveTo identify the anatomical relationship between the rectum and its surrounding tissues so as to de-sign a reasonable plane for resection of rectal cancer. MethodsThe pelvis of a cadaver was dissected transversely and the ana-tomical relationship was observed between the rectum and its surrounding tissues on different planes. ResultsThere were clear tissue spaces between the rectum and its surrounding tissues such as the bladder ......
