直肠肛门测压与生物反馈治疗功能性便秘在临床中的应用

目的探讨功能性便秘患者直肠肛门压力变化及生物反馈治疗对功能性便秘的疗效。方法180例功能性便秘患者（便秘组）被纳入本研究，采用维迪胃肠肠动力检测和生物反馈仪行直肠肛门测压和生物反馈治疗，治疗前后分别对患者进行临床症状评分，并记录直肠、肛管静息压、肛管自主收缩持续时间及直肠肛门抑制反射域。60倒无排便异常患者（对照组）作为正常对照，接受直肠肛门测压。结果①与正常对照组比较，功能性便秘患者直肠、肛管静息压、肛管自主收缩持续时间及直肠肛门抑剞反射域值均明显增高（P〈0．05）。②治疗后便秘患者临床症状减轻，显效45例，有效96例，总有效率约78．3％。直肠、肛管静息压、肛管自主收缩持续时间及直肠肛门抑制反射域值降低（P〈0．05）。结论功能性便秘患者存在直肠肛门压力异常，生物反馈治疗可通过改善直肠肛门压力异常达到治疗便秘的目的。

Anorectum piezometry and biofeedback treatment for functional constipation

Objective To investigate the pressure of anorectum and the effects of biofeedback treatment in patient with functional constipation.Methods 180 patients were enlisted to take the biofeedback therapy by Weidi stomach intstine enterokinesia detection and biofeedback appearance in the clinic.Theclinic symptoms and anorectum resting prussure,independent duration of contraction of anal canal,anorectum inhibitory reflex value were recorded and compared before and after biofeedback therapy.60 patients without defecation dysfunction were investigated as normal control.Results The anorectum resting prussure,independent duration of contraction of anal canal,anorectum inhibitory reflex value of patients with functional were higher than that of the normal control(P<0.05).After biofeedback therapy,the symptoms improved.The total effective rate was 78.3%.The anorectum resting prussure,independent duration of contraction of anal canal,anorectum inhibitory reflex value were decreased(P<0.05).Conclusion The anoructum prussure dysfunction can be reformed by biofeedback therapy.
