Outcome of ileal pouch after secondary diagnosis of Crohn's disease.

Ileal-pouch anal anastomosis is sometimes performed inappropriately in Crohn's disease patients. The aim of this study was to evaluate long-term results in this subset. In 54 ileal-pouch anal anastomoses performed between 1985 and 1997 for CUD the patient was eventually diagnosed as having Crohn's disease in seven cases.
