Non-steroidal anti-inflammatory drug-induced jejunal and colonic diaphragm disease: a report of two cases.

Two patients with intestinal submucosal diaphragm disease associated with non-steroidal anti-inflammatory drugs are presented. The jejunum was affected in one, and in the other the ascending colon. Most previously reported cases have shown ileal disease and no case to date has shown involvement of the colon. The reasons for the localisation of these diaphragms remain unclear.
