Gastrointestinal stromal tumor (GIST) of the Treitz’s angle– a very rare cause of high bowel obstruction
Journal Title: Journal of Mind and Medical Sciences - Year 2016, Vol 3, Issue 2
Abstract
Gastrointestinal stromal tumors (GIST) are somewhat rare gastrointestinal tumors - approximately 1% to 3% incidence, but they are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs are usually found in the stomach or small intestine but can occur anywhere within the gastrointestinal tract, even in extremely uncommon locations like duodeno-jejunal flexure. Only 3% – 5% of GISTs are located in the duodenum and tumors occurring in the angle of Treitz are even rarer, most published studies being case reports. These tumors have a size ranging from small lesions to large masses and can cause digestive bleeding or high bowel obstruction. This paper is a case presentation illustrating an emergency situation involving a high bowel obstruction caused by a small tumor with an unusual location in the Treitz’s angle. A large percentage of duodenal GISTs are localized in the third and fourth part of the duodenum and may not be found through standard upper endoscopy; only the barium study of the upper gastrointestinal tract highlights the obstruction point. Preoperative diagnosis is difficult but non-invasive imaging techniques like ultrasonography and computed tomography of the abdomen can be helpful. Recently, targeted therapy with inhibitors of tyrosine kinase receptors (IMATINIB) has been introduced for the management of advanced and metastatic tumors. In our opinion the surgical resection with curative intent is the treatment of choice.
