Idiopathic postoperative intussusception.

During the last 11 years idiopathic postoperative intussusception developed in ten children. The incidence was 5.5% of all the intussusceptions. The age ranged from three months to ten years and the interval between two surgical procedures differed from three to eight days. Only one of the patients presented the classical signs of intussusception. In nine of them, the obstructions were in the small bowel. Nine of the ten intussusceptions needed simple manual reduction. Postoperative recovery was uneventful.
