Evaluation of Fecal Microbiome Changes After Antegrade Continence Enema Placement and Initiation of Bowel Flush Regimen

The purpose of this study is to determine if a sustained change in the fecal microbiome occurs after prolonged use of an antegrade continence enema bowel flush regimen. Patients' microbiomes will be evaluated via 16s rRNA sequencing. PEG 3350 will be compared to PEG 3350 with electrolytes

Glycerin will be given to patients based on standard of care, at the discretion of the pediatric gastroenterology and pediatric surgery teams. Glycerin administration will not be randomized. For secondary analysis, the microbiomes of those who have and have not received glycerin will be compared.
