摘要:
传统的腹会阴联合直肠切除术(abdominoperineal excision, APE)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切除术(exralevator abdominoperineal excision, ELAPE)被报道具有肿瘤学优势，最近应用越来越多。尽管相关报道很多，但是，ELAPE是否比传统APE具有优势仍然有很多争议。本文就ELAPE治疗低位直肠癌的研究进展做一综述。
Abstract:
It has been reported that the conventional abdominoperineal excision has the disadvantages of higher rates of positive circumferential resection margin and intraoperative bowel perforation. Extralevator abdominoperineal excision (ELAPE) has become increasingly used because of some evidence of improved oncological outcome. The superiority of extralevator abdominoperineal excision (ELAPE) over conventional abdominoperineal excision (APE) remains controversial, despite the publication of many studies on this issue. The aim of this paper was to review the research progression of extralevator abdominoperineal excision for low rectal cancer.
