ABSTRACT

Gastrointestinal stromal tumors are the most frequent mesenchymal tumors of the digestive system. In the duodenum, their presentation is rare, with less than 5%. Unlike carcinomas, gastrointestinal stromal tumors do not extensively infiltrate the mucosa. Surgical resection with negative section borders without lymphadenectomy is the main treatment with curative intent, and conservative resections are carried out as long as they are feasible from the technical point of view. We present the case of a patient with a gastrointestinal stromal tumor of the duodenum and whose main manifestation was high digestive bleeding. The lesion was resected with negative surgical section borders through a distal partial duodenectomy of the third and fourth portions of the duodenum and with preservation of the pancreas. The intestinal transit was restored by a terminal duodenojejunostomy in a suture plane. At this time, the patient is treated with imatinib mesylate.
