Research progress of cylindrical abdominoperineal resection/extralevator abdominoperineal excision for advanced low rectal cancer / 中华胃肠外科杂志

ABSTRACT

Cylindrical abdominoperineal resection (CAPR), also known as extralevator abdominoperineal excision (ELAPE), has been described as a method for improving the outcome of APR for advanced low rectal cancer, probably because of more pelvic dissection and less positive circumferential resection margin (CRM). Recently, there have been some hot issues associated with CAPR/ELAPE, such as pelvic floor reconstruction methods, prone or lithotomy positioning during pelvic procedure, postoperative chronic perineal pain, postoperative sexual and urinary nerves damage, etc. Individual cylindrical procedure based on clinical and anatomic research may be as effective as CAPR/ELAPE while minimizing the operative trauma and the damage to the nerves of the genital and urinary organs.
