Pathologic lead points are found in a few intussusception patients. To evaluate the pathologic lead points in childhood intussusception, a retrospective review of 227 operated cases of intussusception treated at the Yeungnam University Hospital from January 1986 to April 1999. The patients were divided into 2 groups; idiopathic group 209 cases, (92.1 % and lead points group 18 cases, 7.9 %). Intussusception developed between age two months and six months in both groups. Enteroenteric type of intussusception was relatively more frequent in the lead point group than in idiopathic group. The lead points were veil (10 cases, 52.6 %), Meckel's diverticulum(3 cases, 15.8 %), lymphoma(3 cases, 15.8 %), ectopic pancreas(2 cases, 10.5 %), Henoch-Schonlein purpura(l cases, 5.3 %). The bowel resection rate was 44.4 % in the lead point group and 8.6% in idiopathic group. The recurrence rate was 5.56 % in lead points group and 1.44 % in idiopathic group.
