Evaluation of biofeedback in childhood encopresis
1Department of Medicine and Pediatrics, Montefiore Hospital, Pittsburgh, PA 15213.
Insights
Biofeedback therapy shows promise for childhood encopresis, particularly in children with abnormal defecation patterns. While overall results were similar to mineral oil therapy, specific subgroups benefited more from biofeedback.
Area of Science:
- Pediatric Gastroenterology
- Behavioral Therapy
Background:
- Childhood encopresis is a common functional gastrointestinal disorder.
- Effective treatment options are crucial for improving quality of life.
Purpose of the Study:
- To evaluate the efficacy of biofeedback therapy compared to mineral oil therapy for childhood encopresis.
- To assess the specificity of biofeedback in children with normal versus abnormal defecation patterns.
Main Methods:
- Prospective study of 50 children with encopresis, randomized to biofeedback (B) or mineral oil (M).
- Single blinded design with outcome assessment at 3, 6, and 12 months.
- Comparison of treatment outcomes based on normal (n=32) and abnormal (n=18) defecation patterns.
Main Results:
- No significant overall clinical outcome differences between biofeedback and mineral oil at 12 months.
- Biofeedback showed higher remission/improvement rates in children with abnormal defecation patterns (6/9) versus mineral oil (3/9) at 12 months.
- Children with normal defecation patterns responded better to mineral oil (71%) than biofeedback (40%) at 12 months.
Conclusions:
- Biofeedback therapy may be a beneficial treatment for childhood encopresis, especially in cases with abnormal defecation patterns.
- Further research is warranted to explore the specific role of biofeedback in managing encopresis.
- Treatment approach may need to be tailored based on individual defecation patterns.
Abstract:
In order to evaluate the efficacy of biofeedback for childhood encopresis, 50 children with encopresis were prospectively studied and randomized to receive biofeedback (B) or mineral oil therapy (M). Specificity of biofeedback was also evaluated by comparing outcomes of both regimens in children with normal (n = 32) and abnormal (n = 18) defecation patterns. Using a single blinded design, there were no significant differences in clinical outcomes between the 24 children receiving B and the 26 children receiving M at 3, 6, and 12 months. However, at 12 months six of nine children with abnormal defecation patterns were in remission or markedly improved after receiving B, compared to only three of nine children receiving M. In contrast, children with normal patterns appeared to respond better to M than did those receiving B (71 vs. 40% at 12 months). Biofeedback appears to warrant further evaluation in children with encopresis and abnormal defecation patterns.
