  • Title: Antiperistaltic (retrograde) intussusception after Roux-en-Y gastric bypass.
    Author: Goverman J, Greenwald M, Gellman L, Gadaleta D.
    Journal: Am Surg; 2004 Jan; 70(1):67-70. PubMed ID: 14964552.
    Abstract:
    Adult intussusception has been described after various types of gastrointestinal surgery. In some instances there may be intussusception of the jejunum into the stomach via a gastrointestinal stoma, a rare complication known as jejunogastric intussusception (JGI). We present a retrospective review of two cases of retrograde intussusception occurring years after open Roux-en-Y gastric bypass (RYGB) for morbid obesity. To our knowledge there have been no documented reports of JGI occurring after RYGB and only scattered reports of JGI after Roux-en-Y reconstruction in general. Two reports of intussusception following RYGB were identified in the English literature and comprised three patients, only one of whom suffered a retrograde intussusception. As the number of RYGB procedures continues to rise, we will likely see more of this entity; and it is therefore crucial that surgeons consider acute and chronic intussusception as a cause of abdominal pain in patients who have undergone RYGB.
