Abstract
Aim of the study: To evaluate the role of preoperative prophylactic biofeedback therapy on the anorectal continence of patients with high anal fistula who will be subjected to fistulectomy operation. Methods: Prospective study on forty patients divided into two equal groups the first group have twenty patients with high anal fistulae who had undergone prophylactic preoperative anorectal biofeedback, their age ranged between 27 and 75 years with mean age of 41.35 years,the other group contained the other twenty patients with high anal fistula who didn`t receive the prophylactic preoperative anorectal biofeedback therapy, their age ranged between 18 and 57 years with mean age of 39.45 years . Six sessions of biofeedback were done for the patients in the biofeedback group, these sessions were done two weeks preoperatively , one session every other day. Results: The patients were assessed 8-12 weeks postoperatively after complete healing of the wound and their continence postoperatively was assessed using Wexner and Farag score. Among these forty patients only four of them had developed anal incontinence with varying degrees (two of them gas incontinence and another two developed complete stool incontinence), these four patients belong to the group which had not received preoperative prophylactic biofeedback therapy, on the other hand, non of the patients who had received prophylactic preoperative biofeedback had developed incontinence.
