Abstract:
Gastrointestinal stromal tumors (GISTs) are rare tumers of the alimentary tract, and these tumors arise from primitive mesenchymal cells. Duodenal GISTs comprise 4-5% of all GISTs. In this article, we report on a case of duodenal GIST in 35-year-old male who presented with a fistulo in ano and anal bleeding. Abdominal computed tomography and magnetic resonance imaging revealed a huge tumor, about 11x7 cm in size, of the duodenum. Duodenoscopy revealed a protruded mass with central deep ulceration on the third portion of the duodenum. Endoscopic biopsies showed subepithelial spindle cell proliferation of the tumor, and this was consistent with GIST. Pylorus-preserving pancreaticoduodenectomy was then performed. He subsequently underwent the sphincter-preserving modified loose Seton surgical technique. The patient did not have any problems postoperatively and he remained symptom-free at 6 months after surgery.
