Objectives: Chronic constipation is a common childhood problem and often caused or worsened by abnormal dynamics of defecation. The aim of this study was to assess the benefit of pelvic floor physical therapy (PFPT), a novel treatment in pediatrics for the treatment of chronic constipation with dyssynergic defecation. Methods: This was a retrospective study of 69 children seen at a pediatric neurogastroenterology program of a large tertiary referral center for chronic constipation and dyssynergic defecation, determined by anorectal manometry and balloon expulsion testing. We compared the clinical outcome of patients who underwent PFPT (n = 49) to control patients (n = 20) whom received only medical treatment (laxatives/stool softeners). Additionally, characteristics of the treatment group were analyzed in relation to therapeutic response. Results: Thirty-seven (76%) of the patients who received physical therapy had improvement in constipation symptoms, compared to 5 (25%) of the patients on conservative treatment (p < 0.01). Additionally, patients who received pelvic physical therapy had fewer hospitalizations for cleanouts (4 vs. 25%, p = 0.01) and colonic surgery than those that were treated with medical therapy exclusively (0 vs. 10%, p = 0.03). Among the patients who received physical therapy, those that suffered from anxiety and/or low muscle tone had a higher response rate (100%). There were no adverse effects from the intervention. Conclusion: The new field of pediatric PFPT is a safe and effective intervention for children with dyssynergic defecation causing or contributing to chronic constipation, particularly in children whose comorbidities include anxiety and low muscle tone.
