肛管及肛管直肠上皮性癌,虽有个别例子用单纯放疗获得治愈,但本病基本上仍以外科为较好的治疗方法。当肿瘤不是太大和发生在齿线和会阴区就可作局部广泛全厚层切除。若发生自齿线或齿线以上的大肿瘤,或肿瘤已累及直肠和/或括约肌,就需选用腹会阴直肠切除术,并将供给直肠的肠系膜血管和淋巴管、肛管周围皮肤、荐骨直肠窝内容等一并切除。当腹股沟淋巴结病理检查证实为转移,则不论作局部手术或根治手术均需作腹股沟清扫术。
Anal and anal canal rectal cancer, although there are some examples of pure radiotherapy to get cured, but the disease is still basically a better treatment for surgery. When the tumor is not too large and occurs in the dentate and perineum areas, it can be used as a local extensive full-thickness resection. If there is a large tumor above the tooth line or above the tooth line, or if the tumor has involving the rectum and/or sphincter, an abdominal perineal resection should be used. The mesenteric and lymphatic vessels, the skin around the anal canal, and the sacrum should be supplied to the rectum. The contents of the rectal fossa were removed together. When the pathological examination of inguinal lymph nodes confirms metastasis, inguinal dissection is required for both local and radical surgery.
