Double-balloon endoscopy-diagnosed multiple small intestinal ulcers in a Churg-Strauss syndrome patient

Abstract

Churg-Strauss syndrome (CSS) is a systemic vascular disorder characterized by severe bronchial asthma, hypereosinophilia, and allergic rhinitis. Small intestinal ulcers associated with CSS are a relatively rare manifestation that causes gastrointestinal bleeding. Multiple deep ulcers with an irregular shape are characteristic of small intestinal involvement of CSS. Video-capsule-endoscopy (VCE), double-balloon endoscopy (DBE) and Spirus assisted enteroscopy have been developed recently and enabled observation of the small intestine. In this case report, we have described a patient with CSS who had multiple deep ulcers in the jejunum detected by oral DBE. Since severe gastrointestinal (GI) involvement has been identified as an independent factor associated with poor outcome, the careful investigation of GI tract must be needed for CSS patients with GI symptoms. We describe the usefulness of DBE for diagnosis of small intestinal ulcers in patient with CSS.
