目的评价生物反馈方法治疗功能性便秘的疗效。方法对我院42例慢性功能性便秘患者进行生物反馈治疗,治疗前后进行临床评估、直肠和盆底肌电描记并进行对比分析。结果生物反馈治疗后患者临床症状改善,肌电图显示盆底肌和腹肌的矛盾运动消失,肛门外括约肌的收缩幅度有不同程度的增加,松弛幅度降低(P<0·05),总有效率为93%,改善伴随症状有效率70%,6个月随访复发率仅5·26%。结论生物反馈治疗功能性便秘有效。
Objective To evaluate the efficacy of biofeedback in the treatment of functional constipation. Methods 42 patients with chronic functional constipation in our hospital were treated with biofeedback. The clinical evaluation, rectal and pelvic electromyography were performed and compared before and after treatment. Results The clinical symptoms of patients after biofeedback were improved. The contrastive motions of pelvic floor muscle and abdominal muscle disappeared with EMG. The contraction amplitude of external anal sphincter increased with different degrees and the relaxation amplitude decreased The efficiency was 93%. The effective rate of concomitant symptoms was 70%. The recurrence rate at 6 months was only 5.26%. Conclusions Biofeedback is effective in treating functional constipation.
