Double balloon endoscopy (DBE) and video capsule endoscopy (VCE) are breakthrough methods for endoscopic examination of the small intestine. Using these modalities, it has been clarified that use of nonsteroidal anti-inflammatory drugs (NSAIDs) induces ulcers not only in upper gastrointestinal tract but also in the small intestine. Furthermore, concentric membranous strictures, so called "diaphragm disease" can be induced with long-term NSAID use in some cases. The best therapy for ulcers induced by NSAIDs in small intestine is cessation of NSAIDs use so far. For these diaphragm-like small intestinal strictures, a balloon dilation therapy using DBE can be performed safety and effectively.
Clinical importance of the location of lesions with regard to mesenteric or antimesenteric side of the small intestine.
