Purpose: To evaluate therapeutic effect of biofeedback therapy according to methods of diagnosis in patients with norelaxing puborectalis syndrome.
Methods: From September, 1, 1998 to February, 30, 1999, the patients who were diagnosed with norelaxing puborectalis syndrome on anal electromyography (EMG) and/or cinedefecography (CD) underwent biofeedback therapy. The patients were divided into 3 groups according to the diagnostic method; CD group - only diagnosed on cinedefecography, EMG group - only diagnosed on anal electromyography, CD EMG group - diagnosed on both tests.
Results: Nineteen patients were diagnosed nonrelaxing puborectalis syndrome on CD and/or EMG. There were 14 females and 5 males with a mean age of 40.8 18.4 years. The patients were classified into CD group; five patients (26.3%); EMG group, eight patients (42.1%); CD EMG group, six patients (31.6%). The patients had 5.4 3.7 sessions of outpatient EMG-based biofeedback sessions. Subjective symptoms after biofeedback therapy improved in 4 (80.0%), 6 (75%), 5 (83%) patients in CD, EMG, CD EMG groups, respectively. There was a statistically significant increase in spontaneous bowel movements, and a reduction in assisted bowel movements after biofeedback therapy in patients in all three groups (p＜0.05). However, no significant difference was found among the three groups.
Conclusion: This study demonstrated that biofeedback therapy had a high therapeutic effect regardless to the diagnostic method. Therefore, biofeedbck therapy can be performed if one test results in the diagnosis of norelaxing puborectalis
syndrome in patients with constipation.
