[Application of extralevator abdominoperineal excision for low rectal carcinoma]

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.
