title: Duodenum-preserving local excision of a gastrointestinal stromal tumor.
abstract: BACKGROUND
  Duodenal gastrointestinal stromal tumors (GISTs) are rare. Because of the complex anatomy of the duodenum, the methods of resection of these tumors are controversial and diverse.
  
  
  METHODS
  We report a case of a duodenal GIST in the anterolateral wall of the second part of the duodenum, which was successfully managed by local excision. The surgery was facilitated by preoperative mapping with Indian ink and navigation by endoscopy to assess the adequacy of resection and to avoid injury to the ampulla.
  
  
  RESULTS
  Reconstruction was successful with a duodenojejunostomy and protected by a nasoduodenal drain.
  
  
  CONCLUSIONS
  The patient had no postoperative complications and the tumor was confirmed to be a GIST of the duodenum successful with an adequate resection margin.
