Jejunogastric intussusception

A UGI (A) shows a jejunogastric intussusception with a filling defect (arrows) reflecting the intussusceptum within the lumen of the stomach. Image B is a second patient with a jejunogastric intussusception. The intussusceptum (jejunum) in the stomach (intussuscipiens) is seen as a filling defect (arrowheads). A nasogastric tube traverses the stomach and enters the efferent limb of the gastrojejunal anastomosis.
