title: [A case of duodenal gastrointestinal stromal tumor treated by pancreas-sparing partial duodenectomy].
abstract: An 79-year-old man admitted our hospital for abdominal mass. Computed tomography showed a tumor measuring about 10 cm in diameter without any metastasis lesion and any sings of local infiltration. Gastroduodenal endoscopy revealed the presence of a submucosal tumor in the third portion of the duodenum, and biopsy revealed tumor cells stained positive for c-kit. These findings were consistent with a GIST and we performed a partial resection of the duodenum sparing the pancreas. Gastrointestinal stromal tumors (GIST) were mainly located in the stomach and the small intestine. Duodenal localization is rare. Surgical approach for GISTs should basically be a partial resection. However, for GISTs located in the duodenum, the partial resection was sometimes difficult and pancreaticoduodenectomy (PD) may be needed, depending on the tumor size and the location of the tumor close to the papilla Vater. Since GIST grew expansively, rarely involving lymph nodes, PD may be an excessive procedure to treat the disease. For this reason pancreas-sparing partial duodenectomy has been introduced for the treatment of duodenal GIST.
