A 69-year-old man was admitted to the hospital with abdominal pain and vomiting. An abdominal X-ray examination and CT scan showed small intestinal air and dilated small intestine. A long tube was inserted for simple obstruction. Intestinal contrast study through a long tube showed stenosis of the jejunum. Double-balloon endoscopy revealed circular ulcer. Laparoscopic assisted partial small intestine resection was carried out without a definite diagnosis. The resected specimen had a 31 x 13 mm size circular ulcer. Histopathological examination, it was diagnosed arteriovenous malformation (AVM). The patient was discharged from the hospital on the 7 th postoperative day without complication. There have been no cases of intestinal obstruction by AVM in Japan.
