传统的腹会阴联合直肠切除术存在环周切缘阳性率高及术中穿孔率较高而影响预后的缺点，肛提肌外腹会阴联合直肠切除术可克服这些缺点，但该术式存在操作复杂、创伤大和并发症多等缺点。通过近几年的临床研究，国内外学者对该术式的适应证、手术方式改良及并发症的防治有了更加深入的认识。本文就经肛提肌外腹会阴联合直肠切除术的特点、手术适应证、研究进展及相关并发症的防治进行讨论。

It has been reported that the conventional abdominoperineal excision has the disadvantages of higher rates of positive circumferential resection margin and intraoperative bowel perforation, which affect the prognosis. The technique of extralevator abdominoperineal excision proposed by Holm et al is used to overcome these disadvantages. But this new concept of abdominoperineal excision causes other new problems, such as increased complexity, major trauma and more complications. With further studies, the advanced knowledge about the indications, modifications and complications of this technique has been obtained by the domestic and overseas surgeons. This article reviews the characteristics of extralevator abdominoperineal excision and its indications , research progress and major associated complications.
