B超胆囊排空功能测定的改良方法研究

目的通过分析对比,找到B超胆囊排空功能测定的改良方法。方法选取30名健康志愿者,同一个人在不同时间分别服用A、B、C三种不同脂餐。A组为两个煎鸡蛋;B组按Jacobs MP脂餐配制;C组:不含乳糖奶粉(美赞臣)54 g,含脂肪为15 g。超声测定各组的各时点胆囊体积、脂餐后胆囊的排空功能。结果 A组较B、C组餐后各时点胆囊体积显著增大(P0.05),各时点胆囊排空率明显减低(P0.05);B组与C组比较无明显差异(P0.05)。结论改良的B超胆囊排空功能测定方法不含乳糖,且效果较好,服用方便,值得在临床推广应用。

Clinical research of the application of ultrasound determination in gallbladder emptying

Objective To find the best way to determine gallbladder emptying with ultrasound. Methods We selected 30 healthy volunteers,randomly assigned then into three groups of A, B, C, 10 cases for every group. Group A was given two fried eggs;group B was given Jacobs MP fatty meal ; group C was given lactose-free milk powder（ Mead Johnson） 100 g containing fat 28 g. The gallbladder size and the gallbladder shrinking function by fat food test were measured with B ultrasound. Results The gallbladder volumes of postprandial at all time points significantly increased（ P 〈 0.05 ） ,while the emptying rate of gallbladder at all time points was distinctly lower in the A group than that of the B, C group （ P 〈 0.05 ）. There were no significant differences between B and C groups （ P 〉 0.05）. Conclusion The application of ultrasound determination in gallbladder emptying is worthy of clinical practice.
