title: [Research progression of extralevator abdominoperineal excision].
abstract: The application of extralevator abdomino-perineal excision (ELAPE) and total mesorectal excision has improved the prognosis of rectal cancer. However, compared with anterior resection for rectal cancer, the circumferential resection margin (CRM) positive rate and intraoperative perforation (IOP) rate are still high. The ELAPE can reduce the CRM positive rate and IOP rate, therefore reduce postoperative local recurrence rate and increase the survival rate of patients. The disadvantage of its trauma, longer operative time, and higher perineum complication in ELAPE is controversial. This review mainly discusses the key points of operative procedure, advantages and disadvantages, research status and development prospects of ELAPE.
