The aim of this study was to identify risk factors for recurrent intussusception after a successful reduction by fluoroscopy-guided air enema, the time required for recurrence, and the association between delayed reduction and the recurrence.


Medical records of 479 consecutive children with intussusception who underwent fluoroscopy-guided air enema between January 2004 and September 2014 were reviewed. Recurrent intussusception was defined as a recurrence within 48 hours of a reduction. Symptom-to-door time was defined as the time from symptom onset to emergency department arrival. Door-to-reduction time was defined as the time from emergency department arrival to reduction. Time-to-recurrence was defined as the time required for recurrence from the first ultrasound diagnosis.


Of the 360 eligible children, 32 had recurrent intussusceptions (8.9%). Multivariable logistic regression showed that age 2 years or older is an independent predictor of recurrent intussusception (odds ratio, 2.39; 95% confidence interval, 1.13-5.02; P = 0.02). Median time to recurrence was 25 hours (18.0-36.0 hours). Although symptom-to-door and door-to-reduction times tended to be longer in the recurrence group, these differences were not significant (12.5 vs 7.0 hours, P = 0.18; 154.0 vs 143.0 minutes, P = 0.67, respectively).


Our data suggest that provision for early recurrence and extended observation may be beneficial for children 2 years or older. Delayed reduction was not associated with recurrent intussusception, but further studies with larger sample sizes are needed to explain this issue.
