Duodenum-preserving local excision of a gastrointestinal stromal tumor.

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.
