ABSTRACT
Intussusception is a common but life threatening gastrointestinal emergency that occurs in the infant or young child. A three-year-old boy presenting with abdominal pain and vomiting was diagnosed to have the target sign on ultrasonography. An ileocolic intussusception was initially reduced using air enema. Recurrent intussusception 12 hours later was reduced by barium enema. In the proper hands, ultrasonography has a high diagnostic accuracy rate for intussusception. For treatment, air enema is usually perferred to barium enema. Air enema is a safe, rapid, and clean procedure that has been shown to achieve a high reduction rate, comparable to that of barium enema. Ultrasonographically-guided hydrostatic reduction of intussusception has also been recently described and is an effective alternative.
