Intestinal intussusception is a rare pathology that usually involves the small intestine and almost always has an identifiable cause in adult patients. It may occur as a rare complication after Roux-en-Y gastric bypass. In recent years, due to the sustained increase of obesity in developed and developing countries, there has been an increase in the use of bariatric surgery as a treatment for this pathology, and among the most commonly performed is the Roux-en-Y gastric bypass. Cases of intussusception have been described in this context, almost always involving jejuno-jejunal anastomosis. In this article, we present a patient who, after Roux-en-Y gastric bypass, developed a gastro-gastric intussusception, which was corrected with resection of the gastric remnant in a satisfactory manner. Intussusception after Roux-en-Y gastric bypass is a rare complication. It is necessary to have a high degree of suspicion in patients with gastrointestinal symptoms with a history of gastric bypass, and in this case, resection of the affected segment, and not just reduction with or without fixation, is the optical management.
