- Abstract
Objective: To describe the anorectal manometry results in the pediatric population with chronic constipation and acquired anorectal disease., Materials and Methods: We reviewed the records of children who were referred to the Motility and Pelvic Floor Laboratory of the Hospital San Jose Tecnologico de Monterrey between 2004-2016 for further evaluation with anorectal manometry and who presented acquired anorectal disease., Results: We reviewed 170 records. The mean age was 7.18 ± 4.51 years old. The prevalence of anorectal disease was 73%. The symptoms more frequently presented were difficult evacuation (78%), painful defecation (67%), large and hard stool (50%) and fecal soiling (49%). 44% of patients with hypotonic external anal sphincter (EAS) presented with soiling and 74% of those had diminished critical volume. Significant manometric values (p<0.05) were EAS resting pressure, maximal squeeze pressure, and critical volume. 97.7% of those who underwent abdomino pelvic coordination evaluation had pelvic floor dyssynergia (anismus)., Conclusions: Contrary to adult population, the manometric values in children with acquire anorectal pathology were within normal values except for the EAS resting pressure and critical volume that were diminished. This could suggest a different mechanism in the pediatric population. Pelvic floor dyssynergia could explain chronic constipation in these patients.
