Gastrogastric intussusception secondary to a gastric carcinoma: Report of a case.

Intussusception is uncommon in the proximal gastrointestinal tract, although a few case reports have been published on gastroduodenal intussusception associated with an anatomical abnormality or intussusceptions at a site of gastrojejunostomy after gastric surgery. We herein present a case of gastrogastric intussusception secondary to a gastric cancer, which presented as vomiting and poor oral intake. A 73-year-old woman was diagnosed with gastric cancer during a cancer screening by esophagogastroduodenoscopy and biopsy. Twenty days later, she presented with acute vomiting, a high fever, an increased heart rate, and severe anemia. Esophagogastroduodenoscopy demonstrated that the mass had been intussuscepted into the gastric lumen and distorted the distal antrum of the stomach. Standard distal subtotal gastrectomy was performed without reduction. Her postoperative course was uneventful.
