Overview
Surgery
Unlike Crohn's disease, ulcerative colitis can generally be cured by surgical removal of the large intestine. This procedure is necessary in the event of exsanguinating hemorrhage, frank perforation or documented or strongly suspected carcinoma. Surgery is also indicated for patients with severe colitis or toxic megacolon. Patients with symptoms that are disabling and do not respond to drugs may wish to consider whether surgery would improve the quality of life.
Ulcerative colitis is a disease that affects many parts of the body outside the intestinal tract. In rare cases the extra-intestinal manifestations of the disease may require removal of the colon.[1]
Another surgical option for ulcerative colitis that is affecting most of the large bowel is called the ileo-anal pouch procedure. This procedure is a two to three step procedure in which the large bowel is removed, except for the rectal stump and anus, and a temporary ileostomy is made. The next part of the surgery can be done in one or two steps and is usually done at six to twelve month intervals from each prior surgery.
In the next step of the surgery an internal pouch is made of the patients' own small bowel and this pouch is then hooked back up internally to the rectal stump so that patient can once again have a reasonably functioning bowel system, all internal. The temporary ileostomy can be reversed at this time so that the patient is now internalized for bowel functions, or in another step to the procedure, the pouch and rectal stump anastamosis can be left inside the patient to heal for some time, while the patient still uses the ileostomy for bowel function. Then on a subsequent surgery the ileostomy is reversed and the patient has internalized bowel function again.
