    Abstract:
    BACKGROUND: Biofeedback is the most widespread rehabilitative therapy for the treatment of anismus after failed conservative treatment. Osteopathy represents an alternative therapy for constipation. The aim of this study was to evaluate short- and long-term results of osteopathic treatment as compared to biofeedback in patients with dyssynergic defecation. METHODS: This was a prospective cohort pilot study on 30 patients with dyssynergic defecation enrolled at the Colorectal Clinic of the University Hospital of Ferrara, Italy, from May 2015 to May 2016 and followed until May 2020. Dyssynergic defecation was defined as the inappropriate contraction of the pelvic floor or less than 20% relaxation of basal resting sphincter pressure (on anal manometry) with adequate propulsive forces during attempted defecation. Dyssynergic patients were divide into 2 treatment groups: 15 patients had osteopathy and 15 patients had biofeedback. Before and 3 months after rehabilitation treatment, all patients had anorectal manometry, defecography, and ultrasound, and were evaluated with the Cleveland Clinic Florida (CCF) constipation score, obstructed defecation syndrome (ODS) score, Colo-rectal-anal Distress Inventory (CRADI-8), Colo-rectal-anal Impact Questionnaire (CRAIQ-7), and the Brusciano Score (BS). To evaluate the efficacy of osteopathy and biofeedback in the long-term, all patients completed the above-mentioned questionnaires 5 years later via a telephone interview. RESULTS: The two treatments were similarly effective in the short term with reduction in questionnaires scores, and increase in the percentage of anal sphincter release at straining at anorectal manometry in both groups. The ODS score was significantly reduced in biofeedback group (p = 0.021). The 3-month post-treatment BS was lower in the osteopathy group, but this just failed to reach statistical significance (p = 0.050). Periodic rehabilitation reinforcements were provided. The CCF constipation score decreased significantly in the osteopathy group (p = 0.023) after 5 years. CONCLUSIONS: Osteopathy is a promising treatment for dyssynergic defecation, and it can be associated with biofeedback.
