A Case of Giant Duodenal GIST Treated by Duodenal Diverticulization

Abstract

The patient was a 67-year-old man who visited our hospital with the chief complaint of tarry stool. Blood examination at the first visit showed severe anemia, with a Hb level of 4.7 g/dl.

Physical examination revealed a huge abdominal mass in the upper right abdomen, and the findings of abdominal CT suggested the diagnosis of primary duodenal GIST. We performed segmental resection of the duodenum, with reconstruction by duodenal diverticulization.

The postoperative course was uneventful and the patient was discharged 10 days after the operation. The tumor measured 11x8x6cm in size, and the histological diagnosis was primary duodenal GIST.
