Intussusception of efferent intragastric loop after gastrojejunostomy--an exceptional cause of high occlusion and hematemesis.

Jejunogastric intussusception (GI) is an extremely rare complication of gastrojejunostomy (GJS) that may appear any time after surgical intervention. Less than 200 cases have been reported so far, on very small series. Young female, 32, who 12 years ago was operated for a gastroduodenal disease that she doesn't know many details about. She presented severe pain in the superior abdominal segment posteriorly irradiated, incoercible biliary nausea followed by hematemesis. The endoscopic, imaging and biological explorations suggested a huge gastric tumor that occupied the whole stomach and was bleeding diffusely. The rapid acute evolution asked for the urgent laparotomy that emphasized: soft tumour mass, intragastrically mobile without any scar at the stomach or duodenum level; adherent to the posterior of the stomach we discovered a ball of jejunal loops that couldn't be undone. The anterior gastrotomy sets the diagnosis: JGI of the efferent loops of a GJS. We hardly managed to reduce the intussusception, without resection, the loop being absolutely viable. In order to prevent a relapse, and because the anastomosis was not justified it was taken down. JGI in a patient presenting GJS must be taken into consideration in the presence of epigastric pain that would not cease, biliary nausea followed by hematemesis and rapid deterioration of general health status.
