[The usefulness of manometry in the determination of the morphology of the anal canal].
The appearance of the new lecture systems for the manometry studies by computer, like the Polygram by Synectics (vector volume), offer the possibility to see the circumferential pressure forces, that even in rest conditions as in voluntary contraction, they keep coaptation of the anal canal, and this will act as a continent closure system in the most distal part of the G.I. tract. The study is with the normal parameters obtained in 14 individuals, considered as normal, getting the mean +/- sd pressure of the anal canal convey in mm Hg, from de anal canal profile in rest as in voluntary contraction, and the maximum variability that could exist between the six profile waves, that are obtained in the same individual to develop an image of the anal canal. This valves will allow the author's to get to the bottom of fecal incontinence derivative from anorectal malformations, defining the pressure valves of muscular hypoplasia or surgical outcomes of the malformations.
