Efficiency of biofeedback therapy for chronic constipation in children

Area of Science:

• Pediatric Gastroenterology
• Colorectal Surgery
• Physical Medicine and Rehabilitation

Background:

• Chronic constipation is a prevalent pediatric disorder with poorly understood mechanisms.
• Conventional treatments for pediatric constipation often yield suboptimal outcomes.
• Biofeedback therapy shows promise but has variable reported efficacy for constipation.

Purpose of the Study:

• To compare the efficacy of biofeedback therapy against conventional treatment for chronic constipation in children.
• To evaluate short-term (3-month) treatment outcomes in pediatric chronic constipation.

Main Methods:

• A randomized controlled study involving 49 children with chronic idiopathic constipation.
• Children were allocated to either conventional therapy (24) or biofeedback therapy (25).
• Assessment included bowel function history, anorectal manometry, and clinical follow-up before and after the 3-month intervention.

Main Results:

• Biofeedback therapy significantly improved rectal sensation threshold, critical volume, and recto-anal inhibitory reflex volume.
• The prevalence of abnormal defecation dynamics was significantly reduced in the biofeedback group post-treatment.
• No statistically significant differences in initial defecation dynamics were observed between groups.

Conclusions:

• Biofeedback therapy is an effective short-term treatment for chronic constipation in children.
• Therapeutic benefits are particularly noted in the normalization of anorectal dynamics and manometric parameters.
• Evidence for the long-term efficacy of biofeedback in pediatric constipation remains inconclusive.
