Biofeedback therapy combined with diet to treating ODS (Anismus): 2 years outcome

摘要

Object: The advantages of biofeedback therapy along with diet in patients with constipation are among the issues discussed nowadays. The aim of this study was to evaluate 2 years outcome of biofeedback therapy along with diet in patients with obstructed defecation syndrome (ODS) (Anismus). Methodology: The focus of this prospective study is a group of 129 patients with ODS constipation, who were referred to two tertiary-care referral academic centers from 2013 to 2016. Patients received biofeedback therapy combined with appropriate diet in cases group and received diet in controls group. Good response was defined as a subject with at least 50 percent improvement from before to after biofeedback therapy on a Cleveland Clinic Florida Constipation Scoring System (CCF). Factors associated with better outcome were analyzed using SPSS 20 software. Results: Out of the 129 patients, 112 patients (86.8%) were female. The mean age of patients was 42.44 ?± 15.05 years. The mean CCF score of the patients before and after biofeedback therapy was 12.41 ?± 4.39 and 6.00 ?± 3.28 respectively in case group ( p -value < 0.001). In addition, the mean CCF score of the patients before and after diet therapy was 12.82 ?± 4.85 and 9.43 ?± 3.79 respectively in control group ( p -value < 0.001). While CCF score in both case and control groups reduced significantly after therapy, the rate of this reduction was higher in case group ( p < 0.001). Conclusion: Our findings suggest that biofeedback therapy combined with diet will improve patients outcome in ODS constipation. Prospective clinical trials with larger sample sizes are recommend allowing for causal correlations.
