title: Leading points in childhood intussusception.
abstract: Children whose intussusception is caused by a specific pathologic lesion are harder to diagnose and have a higher morbidity than those with the idiopathic variety. We have collected and analyzed 31 such cases found in a series of over 500 intussusceptions. The average age of these children was greater than is usually found in most cases, and the duration of the signs and symptoms was also longer than is usually seen. Almost 50% presented with a picture of advanced small bowel obstruction. Fewer barium enemas were done (50%) and none was successful in reducing the intussusception. There was a higher number of ileo-ideal intussusceptions in this group. The commonest leading points were Meckel's diverticula, polyps, and duplications. All patients with leading points required operation; three-fourths had a bowel resection performed. This study of 569 cases suggests that older children with intussusception and children with recurrent intussusception do not necessarily have leading points causing their intussusceptions.
