Jejunogastric intussusception: life-threatening complication occuring 55 years after gastrojejunostomy.

An 80-year-old man presented with acute abdominal pain and hematemesis. He had a history of gastrojejunostomy 55 years previously. Ultrasonography (US) showed intragastric tublar images with peristalsis. Enhanced computed tomography (CT) demonstrated a dilated stomach with an intragastric filling by bowel loops suggestive of jejunogastric intussusception (JGI). Reduction of the JGI was immediately performed without resection of the intussuscepted intestine, and the patient was well postoperatively. JGI is a rare life-threatening complication after gastric surgery. This complication may occur even 55 years after gastric surgery, and preoperative diagnosis is possible by US and CT findings.
