Retrograde jejunoduodenogastric intussusception associated with fully functioning nonballoon nasojejunal feeding catheter: A case report.

When a patient under tube feeding exhibits abrupt intractable gastroesophageal reflux with a sign of catheter migration, we must consider the possibility of catheter-related intussusception. Having a fully functioning feeding catheter with nonballoon tip does not preclude retrograde jejunoduodenogastric intussusception.
