| Popis: | The efficacy of EMG-biofeedback and low-frequency electrical stimulation for the treatment of anal incontinence has not been proven. Our purpose was to evaluate a novel therapeutic concept, termed triple target treatment, which combines amplitude-modulated medium-frequency stimulation and EMG-biofeedback.Patients with anal incontinence were randomly assigned to the triple target regimen or EMG-biofeedback alone for a 9-month treatment period in a multicenter randomized clinical trial with blinded observers (ClincialTrials.gov registration number NCT00525291). Primary end points were changes in the Cleveland Clinic score and the adapted St. Mark's (Vaizey) score at 9 months compared with baseline. Secondary end points included therapy acceptance and proportion of patients achieving continence or improvement in grade or frequency of incontinence.We enrolled 158 patients with anal incontinence. The median decrease in the Cleveland Clinic score from baseline to 9 months was 3 points greater for the triple target regimen than for EMG-biofeedback (95% CI, 1-4; P = .0024). The improvement was 8 points for the triple target regimen (95% CI, 7-9) and 5 points for EMG-biofeedback (95% CI, 4-7). Results were similar for the Vaizey score. Of patients treated for at least 3 months, continence was achieved by 50% of patients with the triple target regimen and 25.8% of those with EMG-biofeedback.The combination of amplitude-modulated medium-frequency electrostimulation with EMG-biofeedback in the triple target regimen is superior to EMG-biofeedback alone in the treatment of anal incontinence. Therapy programs for fecal incontinence are most effective if patients participate for longer than 2 to 3 months. |
