A pilot randomized study comparing extralevator with conventional abdominoperineal excision for low rectal cancer after neoadjuvant chemoradiation

The aims of this study were to assess the feasibility of performing an extralevator abdominoperineal excision (ELAPE) after neoadjuvant chemoradiation (NCRT), to compare the rates of circumferential resection margin (CRM) involvement and intra‐operative perforation (IOP) of the specimen, and to assess the amount of tissue removed around the muscularis propria (MP)/internal sphincter (IS) of the lower rectum in patients with low rectal cancer undergoing ELAPE compared with conventional abdominoperineal excision (CAPE) after NCRT.
