大便失禁约占人口的0.1％～1.5％,因药物疗效不佳,以前只好求助于外科手段,近来已有2/3病人经生物反馈疗法取得疗效。对成形便失禁患者的肛门直肠功能已有较充分的认识,但有关液状便失禁的资料几乎缺如。液状便失禁通常伴有严重的便急,对常规药物治疗反应不良。本研究旨在评估这类患者的肛门直肠感觉运动功能和生物反馈治疗的效果。 Fecal incontinence accounts for about 0.1% to 1.5% of the population. Due to the poor curative effect of the drug, it was previously resorted to surgical techniques. Two thirds of patients have been treated with biofeedback therapy recently. There is ample awareness of anorectal function in patients with incontinence, but there is scarce information on fluid incontinence. Liquid incontinence is usually associated with severe urgency and poor response to routine medical treatment. The aim of this study was to evaluate the effect of anorectal sensory motor function and biofeedback therapy in these patients.
