Intussusception in a pregnant woman.

Abdominal pain in a pregnant woman with a history of laparoscopic Roux-en-Y gastric bypass (LRYGB) in the emergency department is challenging. Intussusception is a rare cause of small bowel obstruction after LRYGB and can lead to intestinal necrosis, perforation, sepsis and death. The authors report a case of a 34-week pregnant patient, previously submitted to LRYGB, presenting to the emergency department with abdominal pain and vomiting. A computed tomography scan suggested the presence of ileoileal intussusception. So, an emergent laparotomy was performed with invagination reduction. The postoperative period was uneventful, as well as pregnancy and caesarian performed 4 weeks after surgery. At the 45-month follow-up, there was no recurrence of intussusception.
