[Organic causes of intestinal intussusception]

Most of the case of intussuception are considered idiopathic, up to 90-95%. In only a small proportion of them an organic cause is identified. The authors reviewed their experience, including 80 cases of intussusception out of which, 14 showed an organic cause. Six cases were lymphomas, four lymphoid hyperplasia of the colon, two Meckel's diverticulum, one enteric cyst and one Henoch's purpura. An organic cause should be suspected in a child with intussusception who is older than the typical idiopathic intussusception age (6-8 months). Also in those cases with a history of a chronic intussusception.
