title: [Clinicopathological characteristics and surgical treatment of duodenal gastrointestinal stromal tumor].
abstract: OBJECTIVE
  To investigate the clinicopathological characteristics and surgical treatment of duodenal gastrointestinal stromal tumor (GIST).
  
  
  METHODS
  Clinicopathological data of 25 cases with duodenal GIST from January 2007 to July 2011 in West China hospital were retrospectively analyzed.
  
  
  RESULTS
  All the patients were identified by pathological examination without specific symptoms. Tumors were located in the bulb area in 2 cases, descending portion in 11 cases, transverse portion in 8 cases, and ascending portion in 4 cases. Two cases were at very low risk, 7 at low risk, 6 at intermediate risk, and 10 at high risk. All the patients received surgical resection, including 11 pancreaticoduodenectomies, 10 local tumor resections, 2 duodenal segmental resections, and 2 distal subtotal gastrectomies. Eighteen patients were followed up from 16 to 39 months and 3 patients recurred 18, 30, and 35 months after operation respectively.
  
  
  CONCLUSIONS
  Duodenal GIST exhibits no distinct clinical characteristics. Complete removal of the tumor is the main choice of treatment.
