PURPOSE
Biofeedback is a major treatment method for constipated patients with non-relaxing puborectalis syndrome. However a significant percent of patients still showed poor outcome, and little has been known about the predictors associated with outcome of biofeedback. The aim of this study was to determine the outcome and identify predictors associated with poor outcome of biofeedback therapy for constipated patients with non- relaxing puborectalis syndrome.
METHODS
Fifty-two constipated patients with non-relaxing puborectalis syndrome (median age, 47 years) who had more than one biofeedback session after defecography were evaluated by standardized questionnaire, before, immediately after treatment, and at follow-up. Clinical bowel symptoms and anorectal physiological studies were analyzed. Any differences in demographics, clinical symptoms, and parameters of anorectal physiological study were evaluated between success group (patients felt improvement in symptoms at follow-up) and failure group (patients felt no improvement).
RESULTS
Follow up (mean follow-up; 17 months) results were evaluated by an independent observer in 45 patients. At post-biofeedback, 42 (81 percents) patients felt improvement in symptoms, including 7 (13 percents) with complete symptom relief. At follow-up, 25 (56 percents) patients felt improvement in symptoms, including 1 (2 percents) with complete symptom relief. There was a significant reduction in difficult defecation (from 81 to 44, 53 percent, from pre-biofeedback to post-biofeedback, and at follow up respectively; P<0.005, P<0.01), sensation of incomplete defecation (from 90 to 50, 40 percent; P< 0.00001, P<0.000005), laxative use (from 25 to 10, 11 percent; P<0.05), and enema use (from 13 to 0, 2 percent; P<0.01, P<0.05). Normal spontaneous bowel movement was increased from 42 percent pre-biofeedback to 81 percent post-biofeedback (P<0.0001), 80 percent at follow up (P<0.0005). Pre-biofeedback presence of symptoms of bowel habit change predict poor outcome (15 vs. 0 percent; failure vs. success, P<0.05). High pressure zone in prebiofeedback manometry was longer in failure group than in success group (2.80 vs 2.01 cm, P<0.05). In the success group, 11 (44 percent) had a rectocele, 1 (4 percent) had a rectal intussussception, 18 (72 percent) had a descending perineal syndrome, and 3 (12 percent) had a sigmoidocele. In the failure group, 4 (20 percent) had a rectocele, and 1 (5 percent) had a rectal intussusception, 14 (70 percent) had a descending perineal syndrome, and a sigmoidocele was not accompanied (P<0.05). Accompanied rectocele, rectal intussusception, descending perineal syndrome, and sigmoidocele did not influence outcome.
CONCLUSIONS
Biofeedback is an effective option and should be considered as the first line therapy. Bowel habit change and long high pressure zone in pre-biofeedback manometry were predictors associated with poor outcome of biofeedback therapy for constipated patients with non-relaxing puborectalis syndrome.
