[An ileal ulcer and diaphragm-type colonic stenosis due to diclofenac].

Nonsteroidal anti-inflammatory drugs (NSAID) are used extensively in the general population. It's well known the adverse effects of NSAID over the upper gastrointestinal tract and small intestine. Enteric-coated and slow release preparations were created in order to prevent those effects. We describe a woman case who took diclofenac for many years and developed both ileal ulceration and diaphragm-like colonic structure. Lesions in lower gastrointestinal tract were infrequent but severe; the lesion were seen on colonoscopy but not on barium studies; the physiopathology of these lesions remains uncertain; and the most efficacy attitude is the suppression of diclofenac.
