Pneumatic reduction of intussusception in children.

Over the past decade, pneumatic reduction has been increasingly accepted as the treatment of choice for pediatric intussusception. However the effectiveness of air compared with the more traditional barium reduction of intussusception continues to be a source of concern and debate. From August 1993 to November 1994, pneumatic reduction was used to treat 75 episodes in 73 patients with proven intussusception at Chang Gung Memorial Hospital, Taoyuan. Two patients underwent air reduction twice because of recurrence following an initial successful reduction. The recurrence rate was 3%. Successful reduction was achieved in 65/75 (87%) episodes. None of the patients experienced any complications following the procedure. In two of the 10 patients in whom reduction failed, one was subsequently found to have a Meckel's diverticulum and the other a duplication cyst as a leading point. This prospective study indicates that air enema is a safe and effective form of treatment for intussusception in infants and children. Pneumatic reduction should be the treatment of choice in the initial management of intussusception.
