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(P0.05),while the emptying rate of gallbladder at all time points was distinctly lower in the A group than that of the B,C group(P0.05).There were no significant differences between B and C groups(P0.05).Conclusion The application of ultrasound determination in gallbladder emptying is worthy of clinical practice.
