Abdominal Perineal Resection

Abdominoperineal resection (APR) is an extensive operation removing the anus and rectum and sigmoid colon with incisions in the abdomen and around the anus. The surgeon may also remove some of the lymph nodes in the groin. This is performed in open, minimally invasive laparoscopic or robotic surgery.
