Gastroduodenal intussusception is a rarely documented condition that occurs secondary to a mobile leading gastric tumor that prolapses into the duodenum. Its typical radiologic presentation includes lumen narrowing, distally converging gastric folds, infolding and outpouching of the gastric wall, gastric intussusceptum presenting as a filling defect, and a leading tumor in the duodenum. The coil spring pattern, characteristic of bowel intussusception, is not a prominent feature. Two cases are presented and discussed.

Article Synopsis
  • Intussusception in the proximal bowel is very rare, especially gastro-gastric intussusception, which is linked to underlying conditions like a Gastrointestinal Stromal Tumor (GIST).
  • A 36-year-old male with acute abdominal pain was diagnosed with gastro-gastric intussusception during surgery, successfully treated with reduction and gastrectomy.
  • Timely diagnosis and surgery are crucial for this rare condition to prevent serious complications.

Gastroduodenal intussusception in an elderly patient: A rare case.

Gastroduodenal intussusception is a rare but important cause of gastric outlet obstruction, particularly in elderly patients. We present the case of an 81-year-old female who arrived at the emergency department with complaints of epigastric pain, nausea, and vomiting. A CT scan revealed gastroduodenal intussusception, while subsequent endoscopy identified a submucosal mass, raising suspicion for either a gastrointestinal stromal tumor (GIST) or pancreatic rest.

Intussusception is a common and well-known surgical pathology. Intussusception in adults is rare, accounting for only 5% of all intussusceptions. Gastrointestinal stromal tumors (GIST) are common mesenchymal tumors of the stomach that can act as a pathological lead point for intussusception.
