    The possibility of recurrent colonic metaplasia occurring as a complication of pelvic ileal pouches after ileo-rectal anastomosis has been raised. Several reports have documented malignant bladder tumours developing in patients many years after an ileocystoplasty. The case of a 50 year old man, who developed a tubulovillous adenoma in the ileal patch 30 years after an ileocystoplasty had been performed to enlarge a tuberculous shrunken bladder, is reported. The adjacent small intestinal mucosa showed features suggestive of colonic metaplasia.
