[Acute intestinal invagination: hydrostatic reduction vs. pneumatic reduction].

We report the results of 100 cases of acute intussusception treated by inflation of the colon with air under controlled pressure. We compare this method with the traditional one and we analyse the advantages of each method. Successful reduction was achieved in 76% of the cases of intussusception treated with a barium enema and in 88% of the cases treated with an air enema. Pneumocolon in the treatment of acute intestinal intussusception is an alternative method that is very effective and with additional advantages such as: less radiation, less cost and less morbidity in case of perforation.
