Abstract:
Roux-en-Y gastric bypass (RYGB) is a surgical technique described in 1970 and performed laparoscopically since 1993. Occlusions are late complications that most often occur more than 6 months after surgery. Internal hernias and intussusception are the two clinical situations that can occur after RYGB. The presentation is that of an occlusion or chronic abdominal pain. Diagnosis can be made by imaging, including abdominal and pelvic CT scans, with ingestion and injection of contrast agents if possible. Treatment is based on surgical exploration.
