Jejunogastric intussusception: therapeutic options.

Acute jejunogastric intussusception is a rare complication of gastric surgery. It presents considerable difficulties in diagnosis unless the index of suspicion is high. Four cases of acute retrograde jejunogastric intussusception are reported. They were managed surgically after diagnosis had been confirmed by upper gastrointestinal contrast studies. In situ resection of the distal portion of gangrenous intussusceptum was performed in one case, while the intussusception could be reduced manually in the other three cases. The importance of early diagnosis in preventing avoidable morbidity and mortality has been stressed. In situ resection is recommended as the method of choice for the management of irreducible, gangrenous intussusception.
