title: Intussusception after Roux-en-Y gastric bypass for morbid obesity: case report and literature review of rare complication.
abstract: Obstruction of the small intestine is a recognized complication after Roux-en-Y gastric bypass surgery for morbid obesity. Reported causes after bariatric surgery include volvulus, adhesion, internal hernia, hemorrhagic bezoar, incarcerated ventral hernia, and intussusception. Intussusception after Roux-en-Y gastric bypass for morbid obesity is rare. The etiology remains largely obscure. A delay in the diagnosis and management may result in catastrophic outcomes. Management should include the early involvement of a bariatric surgeon. We describe the clinical and radiologic presentation of a case of jejunojejunal intussusception 4 years after open Roux-en-Y gastric bypass.
