肌电刺激生物反馈治疗巨结肠患儿术后肛门失禁的效果观察

The Therapeutic Effect of Electrical Stimulation Biofeedback in Treatment of Postoperative Anal Incontinence of Children with Colonic Colon

目的:评估肌电刺激生物反馈对改善先天性巨结肠术后患儿肛门失禁情况的有效性。方法:本研究共纳入39例巨结肠术后2年肛门失禁的患儿,随机分为试验组(n=24)和对照组(n=15),对照组单纯接受主动括约肌收缩训练,试验组在对照组的基础上,采用生物电刺激反馈训练仪进行括约肌电刺激的生物反馈训练。采用肌电评估、直肠肛门测压及李正临床评分评价两组患儿训练前后的临床疗效。结果:经过2个疗程的训练,试验组与对照组患儿训练后肛门失禁的情况均有不同程度改善,但试验组疗效更显著,差异均有统计学意义(P<0.05)。结论:肌电刺激生物反馈可显著改善巨结肠术后患儿肛门失禁情况,较单纯行普通括约肌训练疗效更佳。

Objective：To assess the therapeutic effect of electrical stimulation biofeedback in treatment of postoperative anal Incontinence of children with colonic colon.Method：A total of 39 patients receivied operation of Hirschsprung after 2 years with postoperative incontinence were enrolled in the present study.All the patients were classified into experimental group（n=24） and control group（n=15） randomly.The control group only received active muscle contraction training,and the observation group received muscle electrical stimulation biofeedback training except above treatments.The Electromyography assessment,rectal anal pressure and clinical grading were applied to compare the clinical effects between the two groups.Result：After 2 courses of training,the symptoms of anus incontinence in both groups were improved to some extent,and the experimental group were better than the control group,the differences were statistically significant（P〈0.05）.Conclusion：Electrical stimulation biofeedback could improve the symptom of postoperative incontinence in children receiving operation of Hirschsprung,and show better curative effect than ordinary sphincter training.
