[Intussusception after Billroth II procedure--an uncommon cause of an upper gastrointestinal ileus].

We present a case of a 73-year-old male patient with Korsakow's disease who was admitted with upper gastrointestinal bleeding and recurrent vomiting. He had received partial gastric resection with Billroth II reconstruction 39 years before for recurrent ulcer disease. At gastroscopy erosive gastritis with no active bleeding and a structure-resembling necrotic mucosa suspicious for intussuscepted small bowel was seen. At exploratory laparotomy jejunogastric intussusception of 50 cm of small bowel through Braun's enteroanastomosis into the gastric remnant was found. After reposition the bowel recovered well and resection was unnecessary. As prophylaxis the bowel was partially attached by sutures in terms of a partial Noble's Operation. The patient's recovery was uneventful after surgery. Jejunogastric intussusception is a rare cause of upper gastrointestinal bleeding and ileus.
