Ileoanal Anastomosis for Ulcerative Colitis
This surgery is done to treat ulcerative colitis. The doctor removes all of the large intestine (colon) and the diseased lining of the rectum. This surgery is also called an ileal pouch-anal anastomosis (IPAA).
In an ileoanal procedure, the lining of the rectum is removed, and the lower end of the small intestine (the ileum) is attached to the opening of the anus. The surgeon makes a pouch from the ileum to hold fecal material (stool). The lower end of the pouch is attached to the anus. The muscles around the rectum are left in place. This allows for fairly normal bowel movements.
The ileoanal procedure cures ulcerative colitis by removing all the tissue that the disease could return to.
What To Expect After Surgery
This surgery is sometimes done in two stages. In the first surgery, the doctor removes the large intestine, makes an opening in the abdomen, and attaches the ileum to the opening. This is called an ileostomy. In a second surgery, the pouch is formed from the ileum and then attached to the opening of the anus. Recovery from each surgery takes 1 to 2 weeks. The two steps may be done in the same operation if you are not ill at the time of surgery.
