Ileal pouch-anal anastomosis in patients with indeterminate colitis

Abstract

After ileal pouch-anal anastomosis patients with indeterminate colitis who did not develop Crohn's disease subsequently experienced long-term outcomes nearly identical to patients with chronic ulcerative colitis. Crohn's disease, whether it develops after surgery for chronic ulcerative colitis or indeterminate colitis, is associated with poor long-term outcomes.
