生物反馈训练治疗和灌肠对便秘疗效比较的研究

Comparative research on curative effects of biofeedback training and coloclysis on constipation

目的比较生物反馈训练治疗与灌肠对便秘的疗效，探讨治疗便秘更有效的方法。方法选择2012年1月-2013年12月本院便秘患者120例，其中对照组60例采用灌肠治疗，观察组60例采用生物反馈治疗。比较两组治疗后临床疗效、症状评分及肌电图变化。结果观察组排便间隔、粪便性状、排便困难，用力排便、排便不尽感等评分均低于对照组（P〈0．05）；观察组用力排便时直肠压、肛门压和肛门静息压也均低于对照组（P〈0．05）；观察组盆底表面肌电静息值和快速收缩值也均低于对照组（P〈0．05）；治疗后，观察组矛盾运动为12例，对照组为36例，两组构成比差异显著（P〈0．05）。结论生物反馈训练可明显改善排便困难，对肛门、直肠功能及便秘的症状及体征具有显著改善作用。

Objective To make comparison between curative effects of biofeedback training and coloclysis on constipation, and to explore more effective treatment methods for constipation. Methods Between January 2012 and December 2013, 120 patients with constipation were selected. Sixty patients receiving enema were enrolled in control group, and 60 ones receiving biofeedback training were enrolled in observation group. Comparison was made in the clinical effects, symptom scores, and changes in electromyography between the two groups after the treatment. ~ ＇ The scores of defecation interval, stool, defecation diiticulties/forced defecation, defecation incompletion in the observation group were all lower than those in the control group （P 〈 0.05）. The rectum pressure, anal pressure, and anal resting pressure during the forced defecation in the observation group was lower than that in the control group （P 〈 0.05）. The pelvic floor surface EMG resting values and myoelectric fast contraction values in the observation group were lower than those in the control group （P 〈 0.05）. After the treatment, there were 12 cases of contradiction movement in the observation group and36 ＇cases in the control group, and the difference in the constituent ratios between the two groups was significant （P 〈 0.05）. Conclusion Biofeedback training can significantly improve the difficult defecation, the anus and rectum function, and the symptoms and physical signs of constipation.
