[Efficacy of biofeedback therapy in children with functional constipation]

Area of Science:

• Pediatric Gastroenterology
• Pelvic Floor Rehabilitation
• Biofeedback Therapy

Background:

• Functional constipation is a common pediatric issue, often linked to pelvic floor dysfunction (PFD).
• Pelvic floor dysfunction in children can impede normal defecation, leading to chronic constipation.
• Biofeedback therapy offers a potential non-invasive approach to address PFD-related constipation.

Purpose of the Study:

• To assess the efficacy and benefits of biofeedback therapy for children experiencing functional constipation due to PFD.
• To evaluate the impact of biofeedback on rectal manometry parameters and clinical outcomes in pediatric patients.
• To determine the success rate and safety profile of biofeedback treatment in this population.

Main Methods:

• Children diagnosed with functional constipation and PFD (Rome III criteria) were enrolled.
• Anorectal manometry was used for diagnosis and assessment of treatment effects.
• Biofeedback therapy was administered bi-weekly, with efficacy evaluated in those receiving at least three sessions.

Main Results:

• Rectal maximum contraction pressure during defecation significantly increased with biofeedback sessions (P < 0.01).
• An 88.9% success rate was observed, with 48.1% achieving complete resolution and 29.6% showing improvement.
• The therapy demonstrated a positive clinical response, with excellent or good outcomes in 77.7% of participants.

Conclusions:

• Biofeedback therapy is a safe and effective treatment for pediatric functional constipation caused by PFD.
• The therapy likely enhances constipation relief by improving rectal maximum contraction pressure.
• Biofeedback presents a promising therapeutic option for improving defecation dynamics in children with PFD.
