title: Radial manometric study of the anal canal: preliminary results.
abstract: The pressure profile of the anal canal results from the effects of several muscles mainly the internal and external anal sphincter and the puborectalis. The preliminary results of radial manometric study of the anal canal carried out in 36 healthy volunteers, are reported. Based on the obtained results it is concluded that the anal canal shows a statistically significant difference in the radial distribution of pressure. The anatomo-physiologic mechanisms underlying this phenomenon, are discussed.
