Surgical Management of Duodenal Gastrointestinal Stromal Tumors: A Case Report.

Gastrointestinal stromal tumors (GISTs) represent the most common mesenchymal tumor entity of the gastrointestinal tract. In fewer than 5% of cases, primary GISTs are located in the duodenum. Surgery represents the treatment of choice for localized tumor disease and remains challenging in GISTs located at the duodenum. The optimal surgical approach is currently discussed controversially in the literature due to the fact that extended resections in terms of pancreaticoduodenectomy may cause significant postoperative morbidity and mortality compared to limited resection. We report on a rare case of GIST located in the upper part of the duodenum treated by limited surgical resection. Avoidance of postoperative complications may lead to optimal oncological outcome in selected patients.
