If the pouch fails, the patient will need to have a permanent ileostomy.
- More frequent and more watery bowel movements
- Inflammation of the pouch (pouchitis)
- Blockage of the intestine (bowel obstruction) from internal scar tissue, called adhesions, caused by surgery
- Pouch failure, which happens within five years in about four out of every 100 patients
