A CASE OF EOSINOPHILIC ENTERITIS SUCCESSFULLY OBSERVED BY CAPSULE ENDOSCOPY BEFORE AND AFTER TREATMENT

Abstract

An 82-year-old woman was admitted to our hospital because of epigastralgia with prominent peripheral eosinophilia. Since findings by previous upper gastrointestinal endoscopy and colonoscopy were negative, we performed capsule endoscopy, which revealed multiple reddish and erosive lesions at the upper jejunum. Finally, a diagnosis of eosinophilic enteritis was made from examination of a pathological specimen obtained by single balloon small intestinal endoscopy. Oral predonisolone (25 mg/day) dramatically improved her symptoms and peripheral eosinophilia. This is, to our knowledge, the second case of eosinophilic enteritis successfully observed by capsule endoscopy before and after treatment.
