A Case of Intussusception Due to a Jejunal Gastrointestinal Stromal Tumor

ABSTRACT

Intussusception is seen often in children but relatively few cases occur in adults. In many cases, the etiology of intussusception in adults is a tumor, with adenocarcinoma being the most common tumor in the small intestine. Gastro-intestinal stromal tumor (GIST) is caused by a mutation of the interstitial cells of Cajal, which controls the speed of peristalsis by being involved in the autonomic innervation between the bowel wall and the smooth muscles of the gastrointestinal tract, and is rarely a factor in adult intussusception. We reported a case of a 74-year-old male patient who came to our hospital with hematochezia and was found to have jejunal intussusception from GIST.
