[Intestinal invagination: 12 years of experience]. / Invaginación intestinal: doce años de experiencia.

One hundred and forty two cases of intussusception were treated in our hospital since 1970 to 1982. Patients were divided for analysis into two groups, each consisting of 71 consecutively treated patients. In the second group (1977-1982) the hydrostatic pressure reduction was attempted under general anaesthesia an was successful in 50% of the patients. We compare both groups from the point of view of hydrostatic pressure reduction and conclude that anaesthesia significantly reduces the number of surgical procedures in children with intussusception.
