Non-infantile intussusception.

In Europe and North America, most cases of non-infantile intussusception are associated with intestinal neoplasm. At the University College Hospital, Ibadan, Nigeria, the majority of cases of intussusception seen are ileocecocolic and cecocolic types. These are usually not associated with intestinal neoplasm and simple reduction is all that is required.Intussusception occurring in other segments of the intestinal tract is found to be associated with intestinal neoplasm, mesenteric lymphadenopathy, and ascaris worms. The very mobile cecum and ascending colon found in this population may be related to the high incidence of ileocecocolic and cecocolic intussusception.Indications for resection of intussusception include presence of intestinal neoplasm, irreducibility, gangrenous bowel, and chronicity.
