肛管直肠功能测定在功能性便秘诊疗中的应用

Application of Anorectal Manometry on Functional Constipation

目的探讨肛管直肠功能测定,在功能性便秘患者的诊疗中的意义。方法对41例功能性便秘患者和10例健康志愿者行肛管直肠功能测定,将上述两组资料进行分析以及对比。结果模拟排便时,功能性便秘患者的肛门括约肌松弛压平均值[(84.75±9)mmHg],明显高于正常志愿者平均值[(40.5±5.25)mmHg];便秘患者的排便阈值平均值[(60±5.5)mL],最大耐受阈值[(210±14.3)mL]明显高于正常志愿者平均值[(35±4.2)mL,(115±13.6)mL];功能性便秘患者直肠静息压、肛管静息压、最大缩窄压、肛管高压区长度的平均值与正常对照组比较均无明显差异。结论肛管直肠功能测定在功能性便秘诊疗中发挥着重要作用,应该加以推广。

Objective To investigate the role of Anorectal manometry in the diagnosis and therapy of functional constipation.Methods 41 patients with functional constipation were selected to accept Anorectal manometry. Ten healthy subjects were also selected as control group. Anorectal manometry was performed. The data of anorectal function was analyzed and contrasted between the two groups. Results While simulative defecation , to compared with healthy subjects[ （84.75 ± 9 ） mmHg] ,patients with constipation had higher anal relaxing pressure[ （40.5 ± 5.25） mmHg]. Alse patients with constipation had higher defecating pressure [ （60 ± 5.5） mL] and rectal maximum volume threshold[ （210± 14.3） mL]than healthy subjects [（35 ±4.2）mL, （115± 13.6） mL] .There were no difference in rectal resting pressure, anal resting pressure, maximal aqueezing pressure and length of high-pressure area between two groups. Conclusion Anorectal manometry plays an important part in diagnosis and treatment of functional constipation and deserved to be popularized.
