Acute jejunogastric intussusception.

Acute jejunogastric intussusception is a rare complication following gastric surgery. Three patients were treated for this condition during the past 15 years. Common presenting manifestations are vomiting, hematemesis, upper abdominal pain, and palpable abdominal mass within the left hypogastrium. The diagnosis is established by gastroscopy or upper gastrointestinal radiographs. Four categories of classification are described. Optimal operative management consists of prompt laparotomy. Manual reduction of the intussusception is followed by resection of compromised bowel. Procedures to prevent recurrence are individualized.
