胃排空功能超声测定方法的研究

Study on the method of ultrasonic measurement for gastric emptying function

【摘要】目的探讨超声技术准确测定胃排空功能的方法。方法分别采用胃窦面积法、胃窦体积法和全胃圆柱体法对74例正常志愿者的胃排空时间进行测定，并与核素扫描测定结果比较，准确反映胃排空功能。结果应用全胃圆柱体法超声所测定的胃排空时间与核素扫描测定的胃排空时间相关性最好（r=0．79），差异无统计学意义（P〉0．05）。胃窦面积法、胃窦体积法测得的胃排空时间与核素扫描对比差异均有统计学意义（P〈0．05）。结论应用超声全胃圆柱体法能够准确测定胃排空功能。

Objective To search one ultrasonic method which could evaluate gastric emptying function accurately. Methods The gastric emptying time of 74 normal volunteers were measured by radioisotope scanning and different ultrasonic methods which including gastric antrum area, gastric antrum volume and whole gastric cylinder method. Results The gastric emptying time measured by whole gastric cylinder method related best with those measured by radioisotope scanning （r = 0.79）. The gastric emptying time was no significant difference between the cylinder method and radionuclide scanning （ P ：〉 0.05）. Compared with radionuclide scanning, those measured by gastric antrum area and gastric antrum volume had significant differences. Conclusions The whole gastric cylinder method can accurately reflect the gastric emptying function.
