Arteriovenous malformation (AVM) of the small bowel is a rare disease and can be sometimes difficult to treat due to the diagnostic difficulty. We herein report a case of small intestinal bleeding of AVM successfully treated with double-balloon enteroscopy (DBE) and laparoscope-assisted resection. A 44-year-old man complained of hematochezia and visited the previous doctor. He underwent gastroscopy and colonoscopy, but no bleeding site was detected. However, he rebled 2 days later and became hypotensive. Abdominal computed tomography revealed a hypervascular nodule in the jejunum. He was transferred to our institution for further treatment. DBE was performed and revealed a small pulsatile lesion with a tiny mucosal break. We then injected a marking tattoo. Two days later, he underwent an operation. We were able to easily locate the tattooed lesion laparoscopically and performed jejunal partial resection. His postoperative course was uneventful. DBE enabled a precise diagnosis and minimal invasive surgery.
