  • Title: Duodenojejunal intussusception secondary to primary gastrointestinal stromal tumor: A case report.
    Author: Fujimoto G, Osada S.
    Journal: Int J Surg Case Rep; 2019; 64():15-19. PubMed ID: 31590135.
    Abstract:
    INTRODUCTION: Gastrointestinal stromal tumors (GISTs) in the third portion of the duodenum are rare. Intussusception and obstruction are rarely caused by GISTs because of their tendency to grow in an extraluminal manner. Herein, we report a case involving segmental duodenectomy in a patient with duodenojejunal intussusception secondary to a primary GIST. PRESENTATION OF CASE: A 91-year-old woman with a history of iron-deficiency anemia presented with vomiting and anorexia. Preoperative imaging suggested duodenojejunal intussusception secondary to a GIST in the third portion of the duodenum. Segmental duodenectomy with end-to-end duodenojejunostomy without reduction of the intussusception was performed. At 6 months after the surgery, the patient's anemia had improved and she had no abdominal symptoms. DISCUSSION: Adult intussusception requires surgical resection because most of the patients have intraluminal lesions. The location in relation to the Vater papilla, tumor size, and resection margin should be considered when selecting the type of surgical resection for duodenal GIST. Limited resection appears to be better than pancreaticoduodenectomy with respect to postoperative complications. Considering the age and performance status of this patient, a less invasive maneuver was selected. CONCLUSION: Duodenal GISTs can be a rare cause of intussusception. Thus, a limited surgical resection procedure should be considered in such cases.
