[Reflections on the anorectal pressure profile].
The results of electromanometric studies of the anorectum in 40 children are presented. Owing to a constant flow of rinsing water through the recording tube and owing to a repeated tracing during the same session, there is a more sensitive picture of the anorectal pressure profile than reported hitherto. In addition, the anorectal pressure values are higher. In healthy infants and in most children with constipation and/or encopresis, the anorectal pressure profile can be divided in 2 different parts. These can be differentiated by their amplitude and according to their shape. In a few patients with constipation, there is no difference between the two parts concerning the shape of the anorectal pressure profile, and the values of the anorectal pressures are below normal. But all children with anal sphincter incontinence have a distinctively abnormal anorectal pressure profile, there is not even a numerical difference between the two parts of the anorectal pressure profile, and the anorectal pressures are very low. The relationship between these two parts of the anorectal pressure profile and the muscles of the pelvic floor are discussed and the significance of the mentioned technique evaluated with regard to the diagnosis and treatment of the anorectal disturbances in childhood.
