title: Jejunoduodenal intussusception caused by a solitary polyp in a woman with Peutz-Jeghers syndrome: a case report.
abstract: BACKGROUND
  Peutz-Jeghers syndrome is a rare autosomal dominant disorder characterized by hamartomatous polyps and characteristic mucocutaneous pigmentation. The hamartomatous polyps of Peutz-Jeghers syndrome can cause intestinal occlusion, especially in the small intestine. Intussusception is seen frequently in children, but rarely in adults.
  
  
  METHODS
  We present the case of a 21-year-old female patient who was admitted to our emergency service with symptoms of ileus as a result of intussusception due to duodenal polyps. Radiological and endoscopic findings determined a jejunoduedonal intussusception. After an unsuccessful endoscopic attempt, a laparotomy was performed that revealed a polypoid mass originating from the fourth part of her duodenum, with intussusception of her proximal jejunum.
  
  
  CONCLUSIONS
  Intussusception caused by Peutz-Jeghers syndrome is a rare diagnosis and is mostly jejunojejunal or jejunoileal. Despite the fact that a few duodenojejunal cases have been reported, this is to the best of our knowledge the first case of jejunoduedonal intussusception in a patient with Peutz-Jeghers syndrome to be described in the literature.
