The majority of parents (86%) reported that they were satisfied with Peristeen® as a treatment modality and 67% reported that they would continue using Peristeen® in the treatment of their child's symptoms. DISCUSSION The present study shows that Peristeen® can be a feasible and effective bowel management system for children with intractable FC. In a subset of children, fecal incontinence was treated successfully. The most common adverse effect of treatment was pain. Overall, parental satisfaction was high and no severe complications or side effects were reported.
