Ileoanal Anastomosis for Ulcerative Colitis
Ileoanal Anastomosis for Ulcerative Colitis
Surgery Overview
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
What To Expect
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 (part of the small intestine) to the opening. This surgery is called an ileostomy. The opening will be in place until the second surgery. In the first surgery, the doctor also forms a pouch from the end of ileum and attaches it to the anus. When the pouch is healed, there is a second surgery. In the second surgery, the doctor takes the ileum from the abdomen and attaches it to the pouch, and the opening is closed.
Recovery from each surgery may take a few days or longer in the hospital and a few weeks at home. The two stages are sometimes done in the same surgery.
