Abstract:
Objective: To evaluate the anal sphincter function of congenital anorectal malforotation retrospectively.Methods: With continuous pull through technique, the manometry of 22 congenital anorectal malforotation patients and 24 controls were studied and the results were analysed with their clinical scores. Results: Anal resting pressure in the children with neurogenic anorectum induced by myelodysplasia(21.3?3.4) mmHg was lower than that in normal children(66.7?24.0) mmHg.The maximum contractive pressure of anus in the patients(22.4?3.3) mmHg was lower than that in normal children(129.0?18.8) mmHg. The length of high pressure zone in the patients(12.3?4.6 mm) was lower than that in normal children(23.6?4.6 mm). Rectoanal inhibitory reflex was identified in both patients and normal children. Conclusion:Anorectal manometry might be an effective parameter to evaluate the anal sphincter function of congenital anorectal malformation.
