生物反馈治疗出口梗阻型便秘的临床研究

目的：观察生物反馈治疗对出口梗阻型功能性便秘患者的临床症状及肛管肌电活动的影响。方法：选取89例出口梗阻型功能性便秘患者,进行1个疗程的生物反馈治疗,比较治疗前后患者的临床症状、肛门直肠测压、盆底肌电图及结肠通过时间的变化。结果：经生物反馈治疗后,患者便秘临床症状的有效率为77.53%,治疗后伴随症状、盆底肌反常收缩较治疗前明显减少（均P〈0.01）,治疗后患者排便紧迫感阈值有下降（P=0.01）,胃肠道通过实验较治疗前显著改善（P〈0.05）。结论：生物反馈是治疗出口梗阻型便秘的有效方法。

Prospective study of biofeedback therapy in patients with outlet obstructive constipation

Objective：To observe the effects of biofeedback therapy in patients with the clinical symptoms of constipation and anal elet romyographic activities.Methods：Eighty-nine outlet obstructive constipation patients were treated by biofeedback therapy.Compare the difference before and after the treatment in clinical symptoms, anal elet romyogr aphicactivities and colonic transit time.Results：After biofeedback therapy, the clinical symptoms of constipation in patients with effective rate of 77.53%, after treatment with symptoms, abnormal pelvic floor muscle contraction was significantly reduced compared with before treatment（all P〈0.01）, after treatment with bowel urgency threshold decreased（P=〈0.01）, gastrointestinal tract, the experiment was significantly improved compared with before treatment（P 〈0.05）.Conclusion：Biofeedback treatment of outlet obstruction constipation is an effective way.
