title: [Drug-induced stenosis of the small bowel. Value of enteroclysis].
abstract: The purpose of this study is to characterize radiographically drug-induced ulcerated stenosis of the small bowel and to determine the contribution of enteroclysis in the diagnosis of this rare entity. The clinical pathologic and radiographic findings of 12 patients with drug-induced stenosis (non steroidal anti-inflammatory drugs or potassium salts) evaluated by enteroclysis were reviewed. Three radiological features of strictures were differentiated: diaphragm like stricture, short stricture and stenotic ulceration with girdle aspect. All formulation of NSAIDS and potassium salts are capable of causing the same radiographic and pathologic patterns. Enteroclysis improves the detection of these lesions since intestinal overdistension and correct filling of the loops increase the visualization of small obstructive stenosis and the detection of superficial ulcers. Thus, any patient who has an abnormality of the small bowel should be asked about use of drugs, especially when diaphragm-like strictures are found.
