Retrograde jejunogastric intussusception

Retrograde gastrointestinal intussusception is a rare entity, most commonly reported after gastric resection and gastrojejunostomy. Its occurrence in the absence of previous gastric resection is extremely unusual, with only f our cases reported. All cases were associated with previously placed gastro stomy tubes and implicated these as the inciting factor. We present a fifth case and review the literature. The mechanism of this phenomenon is descri bed and recommendations to prevent this potentially fatal complication are made.
