This could explain the increase in faecal incontinence (FI) in post-menopausal women.
Objective: To evaluate the effect of topical estrogens (TE) in controlling symptoms of FI in post menopausal women. Hypothesis: The application of TE in post menopausal women with FI improves continence. Subjects and
Methods: We performed a prospective double blind randomized trial applying TE to the anal mucosa in postmenopausal women with FI. Study period: 2005-2006. The patients were randomized into 2 groups: I: topical estriol, II: Placebo. In both groups the ointment was applied three times daily for a period of 6 weeks. We compared Wexner's FI score and the FI quality of life scale, before commencing and after 6 weeks of application.
Results: In this period we evaluated 36 patients. Average age: 67 years (48-84). Group I: 18 patients and Group II: 18 patients, one patient was excluded. Wexner's FI score in group I was 11 (5-18) and 7 (0-19) with pre and post application respectively (p= 0,002). Wexner's FI score in group II was 12 and 9 with pre and post application respectively (p= 0.013). When we compared the results between both groups this was not statistically significant (p=0.521).
Conclusions: There is improvement of continence in both groups that had the ointment applied; nonetheless this study could not show that TE improves FI more than a placebo does. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
