A rare cause of coffee-ground vomiting: Retrograde jejunogastric intussusception

Retrograde jejunogastric intussusception is a well-recognised, rare, but potentially fatal long-term complication of gastrojejunostomy or Billroth II reconstruction. Only about 200 cases have been reported in the literature to date. Diagnosis of this condition is difficult in most cases. To avoid mortality, earlydiagnosis and prompt surgical intervention is mandatory. Since gastrojejunostomies with vagotomy are on a declining trend, it is extremely rare to come across such a complication. We report on such a patient who presented with haematemesis.
