Abstract
AbstractNonsteroidal anti-inflammatory drug (NSAID)-induced enteropathy is an increasingly recognized entity. Patients of older age and those suffering from conditions such as arthritis requiring long term NSAIDs are thought to be at greater risk. Introduction of enteroscopic techniques has greatly improved understanding of NSAID-related small intestinal injury. Complementary high-resolution cross-sectional imaging techniques aid in initial evaluation and for exclusion of alternative etiology. Erosions, superficial ulcerations, and short segment strictures are the most commonly described findings. The diagnosis of the condition lies in obtaining relevant history in addition to a high degree of suspicion during investigation of anemia, obscure gastrointestinal bleeding, small bowel obstruction, and protein losing enteropathy. Herein, the authors present a review of pathogenesis and imaging findings of NSAID enteropathy with particular emphasis on distinction from Crohn’s enteropathy.
