A CASE OF ISOLATED CROHN’S DISEASE OF THE GASTRODUODENUM IN WHICH THE ENTIRE GASTROINTESTINAL TRACT WAS EXAMINED BY ENDOSCOPY

Abstract

An 18-year-old male presenting with abdominal pain and melena was admitted to our hospital. On esophagogastroduodenoscopic examination, longitudinal ulcers were observed at the duodenum and a bamboo joint-like appearance was observed at the gastric cardia. Biopsy specimens from the duodenum revealed non-caseating granuloma. There were no remarkable findings on both colonoscopic examination and small intestinal endoscopic examinations (capsule enteroscopy and double balloon enteroscopy). The patient was diagnosed with Crohn’s disease confined to the stomach and duodenum without involvement of the small intestine or colon.
