La motilidad anorrectal en sujetos sanos

this paper described the anorectal manometries performed on a group of 21 healthy subjects, 16 males and 5 females aged =35,9 years as an average (19-51 years). the method of precast catheters and rectal balloon insuflation to induce inhibitory recto anal reflex was used. the achieved results showed =3,24cm (ci=2.95-3.53) for the functional anal canal length; =1,91cm (ci=1.78-2.04) for the internal anal sphincter length that represented 59%of the total anal canal length. sphincteral resting pressure of =65cm h2o (ci=57,29-27,7); relaxation pressure of =43.5 cm h2o (ic=38,05-48,92) and relaxation percentage of x=69,4% (ci=61,84-76,96). the maximum voluntary contraction pressure of the external anal sphincter showed a mean =46.7 cm h2o(ci=41,11-52.29) and the critical volume reached a mean =24,8 cc air(ci=20,05-29,55). all these values were compared with those of the revised literature on anorectal motility in healthy subjects
