- Ileal pouches are formed from loops of terminal ileum, may be anastomosed to rectum to preserve anal sphincter function and restore continuity of bowel
- Contraindicated in Crohn disease due to high risk of fistula and abscess
- Complications: fistula, obstruction, incontinence, anastomotic leaks; 2-7% of cases are due to initially undiagnosed Crohn disease
