The Role of Anorectal Manometry in Pediatric Chronic Refractory Constipation

This research protocol outlines a two-year descriptive cross-sectional study to investigate the role of high-resolution anorectal manometry (HRAM) in children aged 4-18 years with chronic refractory constipation.The study plans to enroll 54 patients at Ain Shams University Specialized Hospital . The study aims to identify different patterns of anorectal dysfunction (like dyssynergic defecation or rectal hyposensitivity) using standardized international protocols. A key goal is to determine if these manometry findings can directly guide specific management strategies, such as biofeedback therapy for dyssynergia or botulinum toxin injections for anal hypertension. improving outcomes for children who do not respond to standard constipation therapies.
