Jejunoduodenogastric intussusception secondary to percutaneous gastrostomy tube in an adult patient.

Intussusception is the most common abdominal emergency in early childhood, but it is rare entity in adults. Jejenoduodenogastric intussusception is an exceedingly rare retrograde small-bowel intussusception. Percutaneous endoscopic gastrostomy (PEG) has become the preferred procedure for establishing enteral feeding in most clinical situations. Despite the fact that it is relatively safe, a number of complications can occur following PEG placement; jejenoduodenogastric intussusception is one of them, but it is a very rare entity. Here, we report a case of jejenoduodenogastric intussusception secondary to placement of a PEG tube in an adult patient. To our knowledge, this is the third case of isolated duodenogastric intussusception being reported.
