生物反馈训练对不同类型功能性便秘的疗效研究

目的　探讨生物反馈训练对不同类型功能性便秘治疗的疗效。方法　对门诊 3 2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、结肠通过时间检查和肌电图检查。结果　出口梗阻型便秘患者(2 0例 )临床症状改善 ,结肠通过时间较治疗前明显缩短 (P <0 .0 5) ,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 .0 5)。慢传输型便秘患者 (12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 ,但无统计学意义 (P >0 .0 5)。结论　生物反馈训练治疗对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

ObjectiveTo assess the t herapeutic effect of biofeedback treatment for different types of functional co nstipation.?Methods32 patients were enlisted to take th e biofeedback training in the clinic. Assessing bowel symptoms, checking colonic transit time and electromyography were made before and after the therapy.?ResultsIn the patients with outlet obstructive constipation (n=20), the symptoms got improved, the colonic transit times decreased, the amplitude of belly and anal contractions increased to varied extents, and the re laxation amplitude reduced. In the patients with outlet obstructive constipation (n=12), the symptoms got improved, the colonic transit time decreased, th e amplitude of belly and anal contractionsl increased, but the relaxation ampli tude reduced only insignificantly.?ConclusionBiofeedba ck treatment is effective for different forms of constipation. It can be one of the most important ways to cure functional constipation.
