Jejuno-anastomotic retrograde intussusception complicating pregnancy following gastric bypass

Small bowel intussusception remains a rare cause of intestinal obstruction in adults and is almost always associated with a lead point, for example a small bowel polyp(1). However, there have been recent reports of small bowel intussusception occurring without a clear lead point in adults that have undergone a laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery for management of obesity(1,2). The current incidence reported in the literature is 0.07% –0.6%, occurring at an average of 36 months postoperatively, and it has been demonstrated in both men and pregnant and non-pregnant women(1-3).
