Brief Summary

Background. Rehabilitation and re-education using instrumental anorectal biofeedback are the main treatment of anorectal functional disorders producing incontinence and outlet obstructed defecation. These treatments imply intubation of patient and several sessions of treatment leading to high consumption of resources and costs. Hypothesis. A cognitive intervention based on original audiovisual programs developed specifically for the management of anorectal functional disorders is effective in correcting anorectal function disorders that cause fecal incontinence and evacuation disorders. Aim. To prove in two different protocols (fecal incontinence and dyssinergic defecation) the efficacy of specifically developed non-instrumental biofeedback techniques. Selection criteria. Patients with fecal incontinence and altered sphincter function and patients with outlet obstructed evacuation referred for biofeedback treatment. Intervention. In separate studies (incontinence and dyssynergic defecation) patients will be randomized into biofeedback and placebo groups. One session of either biofeedback or placebo intervention will be performed at the beginning of the intervention period and patients will be instructed to performed the assigned daily treatment at home. A visit for outcome assessment will be performed at 3 months in incontinence study and at 4 weeks in the dyssinergic defecation study. In addition, in the incontinence study a phone call will be performed after 6 months of the beginning of the study to evaluate treatment outcome. Biofeedback: patients will be taught to control anal and abdominal muscular activity by providing instructions using original video supports. Patients will be instructed to perform the same exercises daily at home in scheduled times. Placebo: a pill of placebo containing 0.3 g glucose will be administered every day at home.

Interventions

BiofeedbackBEHAVIORAL

Three visits will be made throughout the study. The first visit (Day -14) will consist of an evaluation of the inclusion criteria. A pre-treatment anorectal manometry will be performed, and a daily symptom questionnaire will be given to the patient. The second visit will take place 14 days later (Day 0). During this visit, the daily clinical symptom questionnaire will be collected and it will be verified that the patient meets the inclusion criteria. Patients who meet the criteria will be randomized 2:1 to active treatment or placebo. Patients will receive instructions, by means of psychoeducational videos on the exercises to be performed daily at home. A final visit will be performed at the end of the study (3 months in incontinence studies and 4 weeks in dyssynergic defecation studies). In incontinence study a final phone call will be performed at 6 months.

Biofeedback
PlaceboBEHAVIORAL

Three visits will be made throughout the study following the same procedure as patients in the active arm. Patients randomized to placebo treatment will receive instructions to take a pill of placebo containing 0.3 g glucose daily at home. A final visit will be performed at the end of the study alike the active treatment group.
