A retrospective study of sixty consecutive cases of proven intussusception with attempt at contrast enema reduction was performed to evaluate currently proposed contraindications to such reduction. When patient age, duration of symptoms, presence of small bowel obstruction and presence of a dissection sign were considered alone, none of the findings indicated irreducibility. Our overall reduction rate was 72% with a complication rate of 3%. This is similar to previously reported series and we concur with more recent publications that the only contraindications to non-surgical reduction of intussusception are free intraperitoneal air, peritonitis or evidence of infarcted bowel. Only when we encountered a combination of symptoms being present for greater than 48 hours and the presence of both small bowel obstruction and a dissection sign was reduction likely to be unsuccessful. However, the presence of a prognostic indicator occurring alone should not be considered a contraindication.
