What is proctocolectomy and ileostomy?

Proctocolectomy is surgery to remove the large intestine (colon) and rectum. During surgery, a new opening (stoma) is made in the abdomen. Stool now empties into an ostomy bag applied to the skin around the stoma. Or proctocolectomy is used with J-pouch surgery in the anal area so stool passes through the anus.

The main use of this surgery is for inflammatory bowel disease. It may be used in several situations, such as when medicines don't help ulcerative colitis or Crohn's disease, or when holes form in the large intestine.

This surgery cures ulcerative colitis. Most people have long-term success with this surgery.

Surgery will not cure Crohn's disease. But it may give people some time without symptoms. Crohn's disease usually comes back after surgery.
