High Incidence of Recurrent Crohn’s Disease Following Colectomy for Ulcerative Colitis Revealed with Long Follow-Up

Background and Aims Ulcerative colitis (UC) patients with progression of their disease despite optimized medical therapy may warrant “curative” proctocolectomy with end ileostomy or ileo-anal pouch (IPAA) anastomosis. The aim of our study was to assess the incidence of later recurrent ileitis that lead to altering the initial diagnosis to Crohn’s disease (CD).
