Documentation of spontaneous reduction of childhood intussusception by ultrasound.

Spontaneous reduction of a presumed ileo-colonic intussusception was demonstrated by ultrasound examination followed by a barium enema. No premedication or anesthetic had been given to the child. This case illustrates the possible natural history of intussusception rarely confirmed by imaging studies. Intussusception is the most common abdominal emergency of early childhood. Diagnosis and therapy is usually performed with a contrast enema. If unsuccessful, surgical reduction is indicated. We wish to report a case of spontaneous reduction of a presumed ileocolonic intussusception. This was initially diagnosed by ultrasound examination, but had spontaneously reduced by the time a barium enema was performed.
