生物反馈仪治疗功能性便秘的疗效观察

目的探讨生物反馈训练对功能性便秘治疗的疗效。方法对门诊30例功能性便秘患者进行生物反馈训练治疗,治疗前后进行临床评估、肛管测压、结肠通过时间检查和肌电图检查。结果出口梗阻型便秘及混合型便秘患者(22例),临床症状改善,结肠通过时间较治疗前明显缩短(P<0.05);肌电图检查显示腹部和肛门外括约肌的收缩幅度均有不同程度的增加,松弛幅度降低(P<0.05)。慢传输性便秘(8例)临床症状亦改善,结肠通过时间较治疗前亦明显缩短,肌电图检查显示腹部和肛门外括约肌的收缩幅度均有不同程度的增加,松弛幅度降低,但无显著性差异(P>0.05)。结论生物反馈治疗各种类型的功能性便秘均有效,可作为功能性便秘的治疗方法之一。

Biofeedback treatment for different types of functional constipation

Objective To assess the therapeutic effect of biofeedback treatment for different types of functional constipation.Methods 30 patients were enlisted to take the biofeedbake training in the clinic.Assessing bowel symptoms,anorectal manometry,checking colonic transit time and electromyography were made before and after the therapy.Results In the patients with outlet obstructive constipation(n=22),the symptoms had improved,the colonic transit times had decreased,the amplitude of belly and anal contractions increased to varied extents,and the relaxation amplitude had reduced.In the patients with outlet obstructive constipation(n=8),the symptoms had improved,the colonic transit time had decreased,the amplitude of belly and anal contractionsl had inceeased,but the relaxation amplitude had reduced only insignificantly.(Conclusion) Biofeedback treatment is effective for different forms of constipation.It can be one of the most important ways to to cure functional constipation.
