PurposeComplete contrast enema reduction of intussusception is traditionally considered confirmed when contrast is seen refluxing into the terminal ileum. Operative intervention is typically indicated when the intussusception is not completely reduced. This study reviews the outcomes after symptomatic reduction of intussusception without requiring reflux of contrast into the terminal ileum.MethodsA retrospective review of all pediatric patients treated for intussusception between 1996 and 2006 was performed. Diagnostic modality, operative reports, and hospital records were reviewed.ResultsOne hundred sixty-eight patients were treated for intussusception during the study period. Median age was 9.9 months (59 days to 16.7 years). One hundred thirty-seven (81.5%) patients underwent contrast enema as the initial diagnostic/therapeutic modality. On contrast enema, 15 (10.9%) patients demonstrated reduction of the intussusception but without contrast refluxing into the terminal ileum. All 15 patients had improvement of symptoms. Six (40%) patients underwent operative intervention and were found to have a completely reduced intussusception. Two (13.3%) patients had repeat contrast enema the next day confirming complete reduction. The remaining 7 (46.7%) patients were observed without further radiographic studies, and all 7 patients were discharged the following day tolerating full feedings. There were no recurrent intussusceptions.ConclusionNonoperative management may be used in patients with reduced intussusception despite lack of contrast refluxing into the terminal ileum if symptoms resolve.
