RESUMEN
Jejunogastric Intussusceptions is a rare but potentially life threatening complication of a previous gastrectomy or gastrojejunostomy. A 70 years old man presented with severe epigastric pain followed by haematemesis, 8 years after truncal vagotomy and gastrojejunostomy for pyloric stenosis. Ultrasonography revealed dilated stomach with a large intragastric mass which has minimal peristaltic movement. Endoscopy of upper GIT revealed prolapsed segment of jejunal loops through the gastrojejunostomy stoma. Laparotomy disclosed a retrograde type II jejunogastric intussusception and was managed by reduction of jejunogastric intussusception, resection of gangrenous segment and end to end anastomosis. Post operative recovery was uneventful. Retrograde jejunogastric intussusceptions is a rare condition and around 200 cases has been reported since its first description in 1914. Urgent recognition and surgical treatment is mandatory to reduce the mortality rate from this complication.
