Diversion colitis refers to the inflammatory changes that occur in the defunctioned segment of the large intestine following diversion of the faecal stream. We report the histological features in the defunctioned rectums from seven patients: one each with severe constipation and Behçet's disease, two with Crohn's disease with rectal sparing and three with ulcerative colitis. The appearances of diversion colitis in a previously normal rectum are compared with diversion colitis with superimposed inflammatory bowel disease. Lymphoid follicular hyperplasia was found in all cases. This was marked in patients with inflammatory bowel disease, with or without initial rectal involvement. Other changes comprised surface epithelial degeneration and ulceration, mucosal inflammation including crypt abscesses, and crypt branching. Inflammatory and crypt changes were mild, except in ulcerative colitis where changes were marked and resembled those of the proximal colon. Lymphoid hyperplasia is a distinctive feature in diversion colitis. The term follicular proctitis, previously used to indicate chronic ulcerative colitis exclusively, should be re-examined. |
