Recurrent intussusception: Safe use of hydrostatic enema

Recurrent intussusception (RI) occurs in 5% to 8% of patients with intussusception. The authors reviewed their 15-year experience to better define the management of RI. Among 258 patients, 28 (10.8%) had episodes of RI (37 episodes altogether). Twenty-two patients had a single recurrence, four had double recurrence, one had triple recurrence, and one had quadruple recurrence. RI and non-RI patients were compared with respect to symptoms. The incidence of vomiting and bloody stools was significantly lower in the RI group. Ten percent of RI patients had lead points. Thirty percent of RI episodes occurred within 24 hours, and 74% occurred within 6 months. The success rate of hydrostatic enema reduction for recurrent episodes was 62.8%, which is comparable to that for the initial episode (68.9%). Among patients with previous surgery, 36.3% of enemas were successful; after previous enema reduction, 75% were successful. There was no complication related to the enema. Enema reduction is safe and has a good success rate in cases of RI, even after previous surgical reduction.
