Anorectal Biofeedback Therapy may improve Defecation Disorders, Suggests Study
A recent ambispective cohort study published in the Indian Journal of Gastroenterology in July 2026 reveals that anorectal biofeedback therapy offers highly effective, long-lasting relief for functional defecation disorders (FDD). Impressively, 61.4% of patients experienced immediate symptom improvement, and 56.4% sustained this relief nearly two years later.
While FDD, a major sub-type of chronic constipation, famously demonstrates a limited response to standard pharmacotherapy, there has been a noticeable clinical gap regarding the long-term effectiveness and reliable predictors of response for recommended alternative treatments; addressing this vital need, Ayush Agarwal and affiliated colleagues conducted the research with the primary aim of evaluating both the short and long-term effectiveness of a six-session anorectal BFT protocol.
Therefore, the ambispective cohort study tracked 166 adult patients with functional defecation disorders (FDD) who completed six biofeedback sessions between 2018 and 2024. Researchers primarily aimed to see if patients achieved at least a 30% improvement in their constipation scores, while also evaluating other overall symptom relief and long-term outcomes.
Key Clinical Findings of the Study Includes:
Short-Term Efficacy: Investigators revealed that immediately following BFT, 61.4% of patients successfully achieved a greater than 30% improvement in their MCC score.
Symptom Relief: Researchers noted significant statistical reductions (p < 0.001) in specific patient complaints, including incomplete evacuation, excessive straining, and the requirement for manual evacuation alongside improved VAS scores.
Physiological Improvements: Scientists observed a substantial post-treatment increase in both the defecation index and anal relaxation measurements (p < 0.001).
Response Predictors: Experts determined that a younger patient age successfully predicted short-term responsiveness across all different sub-types of FDD.
Long-Term Sustainability: Clinicians demonstrated that among the 110 patients evaluated at a median of 22 months, 56.4% maintained their initial >30% MCC score improvement, confirming that an initial response to BFT is a significant predictor of long-term therapeutic success.
The results suggest that a structured six-session protocol of anorectal BFT serves as a highly effective intervention for FDD, successfully helping a majority of patients achieve significant initial relief and sustaining those critical therapeutic benefits for more than half of the individuals over an extended clinical timeline.
Thus, the study concludes healthcare professionals may consider prioritizing this specialized biofeedback intervention for chronic constipation patients who meet FDD criteria, particularly when traditional pharmacological approaches have proven inadequate in everyday practice.
