Retrograde Intussusception of the Efferent Limb after a Pancreaticojejunostomy

Abstract

Retrograde intussusception is exceedingly rare and has not been reported after a pancreaticojejunostomy. Recurrent retrograde intussusception has been reported only once before. In adults retrograde intussusception has been associated with gastric resection, gastrojejunostomy, Roux- en-Y gastric bypass, and gastrostomy tube placement. We report a case of retrograde intussusception of the efferent limb into the anastomosis of a revised Roux- en-Y bypass of the pancreas. Two long side-to-side anastomoses with plication were performed to prevent a third episode of intussusception involving this patient's Roux- en-Y.

Duodenogastric Intussusception: A Rare Cause of Gastric Outlet Obstruction

“…Retrograde small bowel intussusception is uncommon. Jejunogastric intussusception is most commonly associated with prior surgery and has been described in adults related to gastric resection, Roux-en-Y gastric bypass, pancreaticojejunostomy or gastrojejunostomy (1)(2)(3)(4). Retrograde duodenogastric intussusception is exceedingly rare.…”
