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.
Confused by ulcerative colitis (UC)? No surprise there; it can be a bewildering disease, sometimes easily confused with other gastrointestinal troubles. On top of that, symptoms can disappear for months or even years, then return for no apparent reason. New treatments and strategies, though, can help you take control.

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
