摘要
目的评价生物反馈治疗肌源性大便失禁的疗效。方法利用生物反馈治疗仪 ,应用肌力训练、感觉训练和排便协调性训练等方法进行生物反馈治疗 ,对 17例患者治疗前后分别进行直肠肛门功能的综合评价。结果治疗前患者临床评分为 1 6 6± 0 2 3,治疗后提高至 3 80± 0 4 2 ,临床有效率为 82 %。治疗前后肛管最大收缩压分别为 (73± 2 0 )mmHg、(12 3± 30 )mmHg ;收缩肌电振幅为 (12 2± 32 ) μV、(2 30± 4 1) μV ;持续收缩时间为 (4 1± 2 0 )s、(9 4± 3 0 )s;直肠感觉阈值为(5 0± 12 )ml、(2 0± 10 )ml;感觉收缩时间为 (3 1± 0 4 )s、(1 2± 0 3)s。直肠收缩反射治疗前阳性占 4 1% ,治疗后阳性占 82 %。结论生物反馈治疗可明显提高肛门括约肌收缩力 ,降低直肠感觉阈 ,促进协调性恢复 ,可作为肌源大便失禁选择性的治疗方法。
Objective To evaluate the effect of biofeedback therapy for the treatment of myogenic fecal incontinence. MethodsA general assessment about anorectal function was made on 17 cases receiving biofeedback therapy including muscle power training,sensory training and coordination training. Results The clinical scores before and after biofeedback therapy were 1.66±0.23,3.80±0.42 respectively,with an effective rate of 82%. The anus maximum contracting pressure elevated,(73±20) mm Hg vs. (123±30) mm Hg; myoelectric amplitude increased,(122±32) μV vs. (230±41) μV;Contracting time prolonged,(4.1±2.0) s vs. (9.4±3.0) s; The sensory threshold was lowered,(50±12) ml vs. ( 20± 10) ml;The feel-contract time increased,(3.1±0.4) s vs. (1.2±0.3) s. Positive rectal contraction reflex was seen in 41% patients before therapy compared with 82% after therapy. Conclusions Biofeedback therapy increases contractility of sphincter,decreases threshold of rectal sensory,and is a therapy of choice for myogenic fecal incontinence.
