A Within Subjects Comparison of Two Antegrade Flushing Regimens in Children
In Brief
A Phase 4 clinical trial evaluating Dose Response - NS and USP Glycerin - First Intervention and Effectiveness - NS and USP Glycerin - Second Intervention for Fecal Incontinence and Neurogenic Bowel. Completed, enrolled 5 participants across 1 site.
Detailed Summary
There is a surgical procedure to help children with intractable fecal incontinence gain continence for stool through construction of a tube that connects the abdominal wall to the colon near or through the appendix. This tube allows easy administration of enema solution into the first part of the colon. Putting enema solution through that tube into the colon is called an antegrade continence enema (ACE) and has been shown to work well in helping some but not all children prevent stool accidents. The purpose of this study is to compare a large volume ACE flush using a salt water solution called normal saline with a small volume ACE flush using liquid glycerin. The aims of this study are to: 1) find the most effective dose and flush frequency of each solution needed to prevent stool accidents; 2) compare which solution given at the best dose has the least side effects and 3) to determine if administration of either of the ACE flushing solutions causes electrolyte abnormalities or affects colon health.

Timeline
Interventions
This trial used a repeated measures, single subjects alternating treatments A-B-C-B'-C'-B1' withdrawal design in which all subjects were tested under all conditions and each subject acted as his or her own control. The subjects were randomly assigned to either normal saline or USP glycerin to control for order effects. Baseline data A served as the control and was obtained pre-operatively. The B-C arm evaluated dose-response relationship and was used to identify the minimum dosing volume and frequency of ACE administration of NS and USP Glycerin necessary to promote fecal continence. When the optimal dose as identified, the child continued on that dose for 2 weeks to insure treatment stability and effectiveness.
To prevent statistical bias from subject loss due to treatment failure, each child was randomized to a second treatment sequence once they have achieved continence with minimal side effects on optimal dosing The second phase B'-C'-B1' of the study compared the two regimens at optimal dose and administration frequency. This phase was used to confirm the effectiveness of NS and USP Glycerin at optimal dosing on continence and assess side effects.
