BELTRAN, Marcelo A et al. Duodenal tumors of the gastrointestinal stroma: Review of the recent literature with emphasis on treatment. rev. colomb. cir. [online]. 2014, vol.29, n.2, pp.140-154. ISSN 2011-7582.

Duodenal gastrointestinal stromal tumors (GIST) constitute the most challenging location for the treatment of this intestinal tract neoplasm. Duodenal GIST are relatively uncommon tumors, and their prevalence is very low, accounting for 5% to 7% or less of all surgically resected GISTs. Most published reports on duodenal GIST are case reports or case series. Consequently, the clinical manifestations, radiologic diagnosis, appropriate surgical treatment, and prognostic factors constitute a subject of current controversy. This review mainly addresses the surgical management of duodenal GISTs trying to establish and define surgical options according to GISTs location within the duodenum. Most articles concerning duodenal GISTs state that unlike tumors involving other sites of the gastrointestinal tract, the optimal procedure for duodenal GISTs has not been well characterized. However, when carefully reviewing the published literature on the subject, it was found that surgical approaches to duodenal GISTs are fairly standard among different authors. All take into account the location of GIST in the duodenum and its anatomic relationships to decide whether local resection or Whipple operation should be performed. Based upon this common sense knowledge, defined surgical options for duodenal GISTs according to their localization within the duodenal frame are proposed.
