The presence of a mobile mass in association with pain and vomiting in a patient who has had a previous gastric surgery is considered virtually pathognomic of acute retrograde intussusception.
Retrograde intussusception is the most common type reported after both RYGB and LRYGB [5-8].

DISCUSSION: The term retrograde intussusception
(invagination) was first introduced by John Hunter to define an invagination of the intussusceptum in an antiperistaltic or a proximal direction as opposed to the usual peristaltic or distal direction.
At laparoscopy, there was a retrograde intussusception
of the proximal common limb into the jejuno-jejunostomy.

In one review of 15, 553 gastric bypass surgeries at a single institution, 23 patients developed a retrograde intussusception.
