Abdominoperineal Resection (APR) is a surgical procedure that involves the removal of the rectum, anus, and a portion of the colon, typically performed for rectal cancer. This procedure is often necessary when the cancer is located in the lower part of the rectum or anus.

During the surgery, the surgeon removes the rectum and anus, and a colostomy is usually created to allow waste to exit the body. This is often a life-saving procedure, though it requires significant lifestyle changes due to the need for a permanent colostomy.

Postoperative care includes managing the colostomy, ensuring proper healing, and preventing complications such as infection. Nutritional support and counseling are also important to help patients adjust to their new way of life.

Abdominoperineal resection is an important treatment for rectal cancer, offering survival benefits while significantly improving outcomes for patients with advanced disease.
