Abstract
PURPOSE: Excessive stool frequency and incontinence after anterior resection (AR) or total colectomy (TC) can be refractory to expectancy and antidiarrheal agents. We prospectively assessed efficacy of anorectal biofeedback therapy (BF) in this clinical situation. METHODS: Thirteen patients (10 men and 3 women; mean age, 62.1 (standard error of the mean (SEM), 4.6) years) had more than six bowel movements per day and/or episodes of incontinence, which did not abate after antidiarrheal agents were given for at least six (mean, 27.9 (SEM, 6.3)) months after surgery. All underwent four sessions of outpatient BF. Assessment was by continence questionnaire and anorectal physiology tests, which were administered before and after BF. RESULTS: In seven AR patients, daily stool frequency was decreased (8.7 (SEM, 2.1) before and 4.6 (SEM, 1.2) after;PPPP.
