Acute jejunogastric intussusception.

Our patient represents an example of acute retrograde jejunograstric intussusception with the additional finding of a bleeding jejunal ulcer in the intussusception. The ulcer may have been etiological in precipitating the intussusception, or a consequence of mucosal sloughing in the hemorrhagic intussusception. Early diagnosis and immediate surgical therapy resulted in an uneventful recovery.
