RESUMO
BACKGROUND: Fecal incontinence has a devastating impact on quality of life and imposes a substantial socioeconomic burden. Best medical therapy including biofeedback therapy improves mild symptoms, with minimal impact on moderate to severe symptoms. Surgical management for incontinence carries a degree of morbidity resulting in low uptake and acceptability. While acupuncture is common practice in Singapore for numerous medical conditions, its role in fecal incontinence is relatively novel. In our local context, however, acupuncture is accessible, inexpensive, and potentially well-accepted as a treatment strategy. OBJECTIVE: To determine the effectiveness of Traditional Chinese Medicine acupuncture, compared to biofeedback therapy in the treatment of fecal incontinence. The secondary aim is to investigate the differences in quality of life following treatment. DESIGN: Randomized controlled trial. SETTING: Prospective, single institution study. PATIENTS: Patients with ≥2 episodes of fecal incontinence/week, or St Mark's incontinence score of ≥5 were recruited. Patients were randomized into biofeedback therapy which included 3 sessions over 10 weeks, or 30 sessions of acupuncture over 10 weeks. MAIN OUTCOME MEASURES: Incontinence episodes, St. Mark's Score and Fecal Incontinence Quality of Life scale. RESULTS: Eighty-five patients were randomized into biofeedback therapy (n=46) or acupuncture (n = 39). Demographics and baseline clinical characteristics were not different (p > 0.05). Overall median incontinence episodes were reduced in both, with the acupuncture arm reporting significantly fewer at week 15 (p < 0.001). Acupuncture also improved quality of life, with improvement in lifestyle, coping, depression, and embarrassment at week 15 (p < 0.05). While the St. Mark's score was significantly reduced in both arms at week 15 (p < 0.001), the acupuncture arm's score was significantly lower (p = 0.002). LIMITATIONS: Longer follow-up required. CONCLUSIONS: Acupuncture is clinically effective and improves quality of life in patients with fecal incontinence. See Video Abstract. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov: NCT04276350.
