Abstract
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 31×13 mm size circular ulcer. Histopathological examination, it was diagnosed arteriovenous malformation (AVM). The patient was discharged from the hospital on the 7th postoperative day without complication. There have been no cases of intestinal obstruction by AVM in Japan.
