经直肠多谱勒超声对内痔分期诊断意义的临床研究

Clinical study on the diagnostic value of proctoscopic Doppler ultrasound on internal hemorrhoids

目的研究经直肠多谱勒超声对内痔分期的诊断意义。方法采用德国DWL公司Dop-Hemo对80例患者进行经直肠多谱勒超声检查。结果经直肠多谱勒超声可以得出内痔病情程度与平均峰值流速呈正比的趋势,超声信号的部位多在齿线上2～3cm,一般只有3～4个分支。但分支的部位存在变异,多数在3,7,11点,有17例(21.25%)存在一支或多支的部位变异。结论多谱勒超声所得到的直肠上动脉分支的血流动力学指标有望为现有只通过临床表现确诊分期提供科学数据。

Objective To study and evaluate the diagnostic value of proctpscopic Doppler ultrasound on internal hemorrhoids. Methods Eighty patients with internal hemorrhoids were examined by Dop - Hemo manufactured by DWL. Results Average systolic peak flow velocity was proportional to order of severity of internal hemorrhoids. Ultrasound signal generally occurred upwards toothed portion 2～3 cm, and there were generally 3～4 branches of uperior rectal artery, but was variation of their position, mostly located at right foreside,right rearward,left middle part of anal canal. There were 17 patients （21. 25% ） who had variation on their branches. Conclusion The hemodynamic data of uperior rectal artery by proctoscopic Doppler ultrasound hopefully provide objective data for making a definite diagnosis of internal hemorrhoids＇ stage.
