[The usefulness and evaluation of postanorectoplasty sagittal posterior biofeedback].

Posterior sagittal anorectoplasty (ARPSP) was described at first of the 80-90 decade like a new surgical technique for the anorectal malformation treatment and derived fecal incontinence. We have evaluated 35 of 67 ARPSP using biofeedback techniques (BFB) before surgery as restore system to striate muscle. Manometric values of the canal anal profile (PCA), postoperative external sphincter pressure and postoperative, first and last BFB voluntary contraction pressure shows clearly the differences between surgical intervention and BFB outcome. The author's opinion is that BFB is the indispensable therapy in the ARPSP postoperative to lend the patients get optimal fecal continence.
