A rare cause of haematemesis: retrograde jejunogastric intussusception.

Retrograde Jejunogastric intussusception is a well-recognised, rare but potentially fatal, long-term complication of gastro-jejunostomy or Billroth-II reconstruction. Only about 200 cases have been reported in literature to date. Diagnosis of this condition is difficult in most of the cases. To avoid mortality early diagnosis 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 such a case that presented with haematemesis.
