1568 A Case of Small Bowel Intussusception Occurring Six Years After Laparoscopic RYGB

Abstract

Abstract Introduction We present a case of small bowel intussusception occurring in a female who had previously undergone Laparoscopic RYGB. Few case reports of retrograde intussusception occurring in pregnant patients with a history of LRYBG have been published. Up to our knowledge, this is the first case of this rare complication presenting in the postnatal period. Case report Our patient, a female in her thirties, gave birth to a healthy baby via caesarian section six years after her LRYGB. On the day following her operation, she experienced epigastric severe, progressive abdominal pain associated with nausea and vomiting. Abdominal examination showed epigastric and left upper quadrant tenderness, hypoactive bowel sounds and no palpable masses. Small bowel obstruction was suspected. A nasogastric tube was inserted and an abdominal CT scan with oral contrast was ordered. The CT scan showed multiple concentric segments of small bowel loops representing the intussusceptum pulled into the intussuscipiens, giving the classic doughnut sign. The patient was subsequently taken to theatre for a laparotomy. The mass was comprised of the biliopancreatic limb which was dilated as the common limb was retrogradely intussuscepting into it. The bowel was ischemic and remained so after manual reduction. A 45cm ischemic segment was resected and then primary re-anastomosis was done. Her postoperative course was unremarkable. Discussion Intussusception can present years after the original surgery, and imaging is not always reliable. Seeing as bariatric surgery is getting more popular, physicians should be well aware of this serious complication as delay in diagnosis increases morbidity and mortality.
