Low anterior resection and abdominoperineal resection

Abstract

Low anterior resection (LAR) and abdominoperineal resection (APR) are the primary surgical interventions for rectal cancer. Proctectomy with an ultra-low or colo-anal anastomosis can also be performed as part of the surgical treatment for benign diseases, such as ulcerative colitis and familial adenomatous polyposis. The procedures are performed both open and laparoscopically, depending on various patient factors, disease pathophysiology, and surgeon preference. Robotic LAR or APR may also be performed with similar outcomes depending on surgeon experience.
