Background: Antegrade continence enema (ACE) is a recognized therapeutic option in the management of pediatric refractory constipation. Data on the long-term outcome of patients who fail to improve after an ACE-procedure are lacking.
Purpose: To describe the rate of ACE bowel management failure in pediatric refractory constipation, and the management and long term outcome of these patients.
Methods: Retrospective analysis of a cohort of patients that underwent ACE-procedure and had at least 3-year-follow-up. Detailed analysis of subsequent treatment and outcome of those patients with a poor functional outcome was performed.
Results: 76 patients were included. 12 (16%) failed successful bowel management after ACE requiring additional intervention. Mean follow-up was 66.3 (range 35-95 months) after ACE-procedure. Colonic motility studies demonstrated colonic neuropathy in 7 patients (58%); abnormal motility in 4 patients (33%), and abnormal left-sided colonic motility in 1 patient (9%). All 12 patients were ultimately treated surgically. Nine patients (75%) had marked clinical improvement, whereas 3 patients (25%) continued to have poor function issues at long term follow-up.
Conclusions: Colonic resection, either segmental or total, led to improvement or resolution of symptoms in the majority of patients who failed cecostomy. However, this is a complex and heterogeneous group and some patients will have continued issues.
