Rectal resections repair damage to the rectum caused by diseases of the lower digestive tract, such as cancer, diverticulitis, and inflammatory bowel disease (ulcerative colitis and Crohn's disease). Injury, obstruction, and ischemia (compromised blood...
supply) may require rectal resection. Masses and scar tissue can grow within the rectum, causing blockages that prevent normal elimination of feces. Other diseases, such as diverticulitis and ulcerative colitis, can cause perforations in the rectum. Surgical removal of the damaged area can return normal rectal function.

An abdominoperineal resection, formally known as abdominoperineal resection of the rectum and abdominoperineal excision of the rectum or simply abdominoperineal excision, is a surgery for rectal cancer. It is frequently abbreviated as AP resection and APR.
This operation is one of the less commonly performed by general surgeons, although they are specifically trained to perform this operation. As low case volumes in rectal surgery have been found to be associated with higher complication rates, it is often centralised in larger centres, where case volumes are higher.
