The use of an air enema in the diagnosis and reduction of intussuscept
ion, using a simple home-made device, was prospectively studied in 36
children with the tentative diagnosis of intussusception. Plain abdomi
nal films were inconclusive in 19 patients (53%). Using an air enema,
the diagnosis of intussusception was easily reached or excluded in all
suspected cases. Twenty-nine patients had intussusception. Their ages
ranged from 3 to 20 months (mean: 7 months), and all had ileo-colic i
nvolvement. Pneumatic reduction was successful in 23 cases (79%), and
reduction was completed within 2-3 minutes in all successfully reduced
cases. At operation, three children had a tear of the sero-muscular l
ayer of the transverse colon, but there were no perforations or recurr
ences of the intussusception in the immediate post-reduction or follow
-up period (1-25 months). An air enema is a safe, cheap, clean and rel
iable procedure for the diagnosis and reduction of intussusception, an
d can now be considered as the treatment of choice in uncomplicated in
tussusception.
