A 61-year-old woman was referred to our hospital for a double balloon endoscopy (DBE) examination of small intestine. She had undergone laparotomy for a perforated ulcer of the 3
rd portion in the duodenum 3 years prior to this admission. Esophagogastroduodenoscopy at the previous hospital revealed multiple ulcers in the 2
nd and 3
rd portions in the duodenum. DBE revealed multiple ulcer scars in the proximal jejunum. Zollinger-Ellison syndrome was suspected from the distribution of the ulcers and scars. Serum gastrin was high and a selective arterial calcium injection test showed a step up of gastrin level only in the gastroduodenal artery area. We diagnosed a gastrinoma located on the ventral side of the 2
nd portion of the duodenum from imaging studies. The tumor was extirpated and histologically found to be a neuroendocrine tumor in a lymph node. Serum gastrin level decreased to the normal range a day after surgery.
