[A case of idiopathic intussusception of the stomach].

A 73-year-old man was admitted to our hospital because of vomiting. A fist-sized tumor with tenderness was palpated on his epigastric region. Fluoroscopic examination of the stomach showed narrow body and dilated antrum with intussusception. Endoscopic findings revealed fold convergence to the antrum. Intraoperatively, the body of the stomach was invaginated into the antrum with hepatoduodenal ligament. It was difficult to repair or resect, and a gastrojejunostomy was performed. On the 10th operative day, fluoroscopic examination of the stomach showed no intussusception of the stomach and no lesion in the upper gastrointestinal tract. To our knowledge, such cases of idiopathic intussusception of the stomach are rare.
