Colonic diaphragm formation

Colonic diaphragm formation is a rare and poorly understood side effect of NSAID use that can have serious consequences. Many NSAIDs have been associated with this complication, but most followed the introduction of extended-release NSAIDs and a disproportionate number have occurred with enteric-coated diclofenac preparations. Chronic NSAID-induced colonic ulceration may persist because of antibodies to cyclooxygenase, or the influence of bile acids, bacteria, food antigens or neutrophil chemoattractants. Of the 33 previously published cases in the English literature, the clinical and laboratory features that prompted investigation most often are listed in Table 1. They were most frequent in the right colon (Table 2). The differential diagnosis for the strictures includes Crohn’s disease and colon cancer.
