[Jejunogastric intussusception. Apropos of a case].

Jejunogastric intussusception is a rare complication after gastric surgery. The authors report a case of acute jejunogastric intussusception diagnosed in a 57-year-old woman, 22 years after vagotomy and gastroenterostomy for duodenal ulcer. There are three types of jejunogastric intussusception: 1) the acute type, presenting as a surgical emergency, and characterized by a sudden onset of cramp-like epigastric pain, followed by nausea and vomiting, with a palpable epigastric mass. 2) the chronic recurrent type, which may progress to the acute type of may result in severe disability, and may require corrective surgery depending on the severity of the symptoms. 3) the acute post-operative type, presenting on the 4th or 5th post-operative day, and usually improving with conservative treatment.
