ABSTRACT
We usually use yolks to assess gallbladder motility by ultrasonography. In this study, we evaluated liquid type CalorieMate as a simple oral stimulus instead of yolks. The volunteers (n = 27) underwent ultrasonography before, 30 min after, and 60 min after taking liquid type CalorieMate. Gallbladder volume and the ejection fraction were measured by ellipsoid method. The mean fasting gallbladder volume, 30-min ejection fraction, and 60-min one were 13.5 ml, 53%, and 62%, respectively. These results were similar to the previous reports by yolks. If the fasting volume is lower than 4ml, they should take re-examination after longer fast to reduce the influence of the dinner the day before the exam. In conclusion, liquid type CalorieMate is useful stimulus to assess gallbladder motility.
