A case of small intestinal Dieulafoy’s ulcer with active bleeding stopped by double balloon endoscopy

Abstract

The patient was a 78-year-old woman who had bloody stool and visited our hospital the same day she noticed this. She was suspected of having small intestinal bleeding because of extravasation in the small intestine on computed tomography, and emergency double balloon endoscopy was performed. Small intestinal Dieulafoy’s ulcer with active bleeding was detected, which was stopped by the clip method. While diagnosing small intestinal bleeding can be difficult, we were able to obtain an early diagnosis and start therapy thanks to double balloon endoscopy with good timing. Double balloon endoscopy is considered to be the first choice of treatment for small intestinal bleeding because the diagnosis and treatment can be performed at the same time. Given that few reports have described small intestinal Dieulafoy’s ulcer, we feel that the findings of this case are important.
