Anorectal manometry presents adiagnostic tool designed to evaluate functional parameters of anorectal activity. During the last decades, 3D High Resolution (HR) manometry has been developed. Solid catheters with miniaturized semiconductor sensors enable exact measurement with high resolution and creation of 3D pressure models of anorectum. In comparison with water-perfused catheters, HR manometry offers more exact and detailed data used for the assessment of anorectal functional disorders. Anorectal manometry should be performed in children with defecation stereotype disorders such as constipation or incontinence. In younger children, Hirschprung'sdisease can be confirmed/ruled out. In older children, functional impairment of anal sphincters, rectal sensation disorders or pelvis floor dysfunction can be diagnosed. Anorectal manometry should also be performed in children undergoing biofeedback therapy. Manometry protocol contains resting pressures of anal sphincters, squeeze manoeuvre pressure, bear down manoeuvre, cough reflex, rectoanal inhibition reflex, parameters of rectal sensitivity and compliance. Anorectal manometry results are used subsequently to determine the individualized treatment plan.
