INTRODUCTION: Chronic Idiopathic Constipation (CIC) is a common pediatric gastrointestinal disorder (GI) characterized by persistent difficulty in defecation, with no identifiable underlying cause. Although most patients are successfully treated with medical therapies, surgical intervention is often needed for refractory disease. We evaluated the impact of Antegrade Continence Enemas (ACE) and Botulinum Toxin (BT) injection to the internal anal sphincter on laxative use, symptom resolution, and healthcare utilization.
METHODS: A retrospective chart review was conducted to identify patients ≤ 18 years old presenting to a pediatric surgery clinic with a chief complaint of CIC between 1 March 2014 and 1 March 2024. Patients meeting the Rome IV criteria for idiopathic constipation and fecal incontinence were included. Surgical procedures were categorized into BT injection or ACE channel creation. The primary outcome was change in daily oral laxative use at 1 year, and secondary outcomes included symptom resolution and CIC-healthcare utilization at 1 year postoperatively.
RESULTS: Of the 125 children who presented with CIC, 47 (37.6%) underwent surgery. Mean age was 6 years at the time of surgery. 17 (36.2%) had ACE channel creation, while 30 (63.8%) received BT injections. At 1 year, daily oral laxative polypharmacy decreased from 60.2% to 41.0%, p < 0.001, with a greater reduction in ACE than BT (adjusted mean difference: -1.05, 95% CI: -1.75 to 0.34, p = 0.004) after adjusting for demographics and baseline clinical factors. Overall, symptom resolution of encopresis (79.1% to 39.5%, p = 0.001), abdominal pain (88.4% to 27.9%, p < 0.001), and abdominal distension (67.4% to 27.9%, p < 0.001) was observed with no significant difference between groups at 1 year. ACE patients had significantly more postoperative outpatient CIC-related visits and no change in ED visits compared to fewer visits in BT patients.
CONCLUSIONS: Both ACE and BT recipients had improvements in constipation-related symptoms and laxative use. However, ACE resulted in a significantly greater reduction in daily laxative use and more postoperative CIC-healthcare visits than BT alone.
