title: [An unusual care of intestinal invagination: jejunojejunal invagination].
abstract: BACKGROUND
  Jejunal intussusception is uncommon in comparison with ileocolic form. It is more frequent in children over 2 years of age and has an atypical subacute presentation. An underlying anatomical cause is usually found.
  
  
  METHODS
  A 14-year-old boy was admitted for abdominal pain with bilious vomiting. The physical examination was normal, with only the ultrasonography showing an intussusception in the left hypochondrium. At laparotomy the diagnosis of jejunal intussusception was made; its reduction was impossible. A resection and end to end anastomosis was performed. The anatomopathology examination found a polyp in ectopic gastric mucosa.
  
  
  CONCLUSIONS
  Jejunal intussusception must be better understood as its diagnosis could be made too late. Surgical exploration is the treatment of choice because of the usual underlying anatomical cause.
