  • Title: Intussusception: an uncommon cause of postoperative small bowel obstruction after gastric bypass.
    Author: Bocker J, Vasile J, Zager J, Goodman E.
    Journal: Obes Surg; 2004 Jan; 14(1):116-9. PubMed ID: 14980045.
    Abstract:
    Intussusception of the jejuno-jejunal anastomosis is a rare complication of the Roux-en-Y gastric bypass (RYGBP). There are only 3 previous cases reported in the surgical literature. We describe 2 adults who developed jejuno-jejunal intussusception requiring emergent laparotomy several months after RYGBP. Both patients underwent exploratory laparotomy after the diagnosis was made with abdominal CT scan. Each patient had an uneventful postoperative course after bowel resection and revision of the enteroenterostomy. Small bowel obstruction due to intussusception may occur many months after RYGBP and may present with non-specific symptoms such as crampy abdominal pain, nausea, and vomiting. The diagnosis of this rare entity is typically made via abdominal CT scan. Treatment mandates urgent abdominal exploration with reduction.
