What is an abdominoperineal resection (AP resection)?

An abdominoperineal resection involves the complete removal of both the anus and the rectum as part of a surgical procedure. This type of surgery is typically performed when there is a need to treat rectal cancer or other serious conditions affecting the lower part of the gastrointestinal tract. By excising both the anus and rectum, this procedure aims to eliminate disease while also addressing issues of local control and recurrence.

In this operation, the surgical team would remove the affected areas from both abdominal and perineal approaches. Following this, a colostomy is usually created to allow for waste elimination since the normal passage through the rectum is no longer available. Understanding the complete removal aspect is crucial, as it sets the foundation for further surgical and postoperative considerations, including care for the colostomy and management of the patient's recovery.
