Multicenter Randomized Controlled Trial to Compare the Outcome of Conservative Triple Target Treatment With EMG-Biofeedback in Chronic Obstipation

Previous studies revealed only a low evidence for the various biofeedback methods and pelvic floor exercises for treatment of chronic obstipation. The number of randomized controlled trials is low with in part significant systemic deficiencies. However, the results from the previous study with 3T treatment in patients with obstructed defecation syndrome (ODS) are so promising that a further randomized controlled trial appears useful to demonstrate a higher degree of evidence. The purpose of this study is to determine whether triple target treatment (3T) or EMG-Biofeedback alone are effective in the treatment of chronic obstipation and if the duration of treatment (3, 6 or 9 months) influence the efficacy.
