Gastrojejunostomy is a commonly performed bypass procedure for various intra- abdominal pathologies. Jejunogastric intussusception is a rare and serious complication following gastrojejunostomy. It was first described in 1914 by Bozzi. These patients may present with features of acute onset intestinal obstruction many years after the primary surgical procedure. Such patients present with a classical triad of sudden onset epigastric pain, vomiting with or with-out hematemesis and a palpable epigastric mass. Upper G.I endoscopy is certainly diagnostic and computed tomography of the abdomen could also help in diagnosis. There is no medical treatment for acute jejunogastric intussusception and the correct treatment is surgical intervention as soon as possible. A mortality rate of 50% has been reported if operated after 48hrs of intussusception. The rarity of the complication and the need for urgent surgical management have prompted us to report this case of a 55years old patient having retrograde intussusception, 30 years after the gastro-enteric anastamosis.
