Abstract

• Author studied with seventeen patients of acute viral hepatitis and seventeen normal volunteer by abdominal ultrasonography who were before and after fat meal after twelve hrs fasting. The results were as follows: 1) The gallbladder wall was significantly thicker than that of control group(2.38±0,54mm) in acute hepatitis group (4.0±1.98mm) (P<0.005) but in convalescent stage of acute viral hepatitis, the thickness of GB wall were decreased significantly to 2.62±0.05mm(P<0.025). There was no significant difference of the inner diameter of the GB between acute viral hepatitis group and convalescent stage of acute viral hepatitis group. 2) There was no significant difference of the inner diameter of the GB between acute viral hepatitis group (5.7±3.42cm²) than that those of normal control group (7.96±2.66cm²) (P<0.05). There was no significant difference of the inner cross sectional area of the GB between convalescent stage of acute viral hepatitis group and normal control group nor acute viral hepatitis group (P>0.1). 4) There was no correlation between the thickness of GB wall and the cross sectional area of the GB. 5) There was no significant difference of predicted outer cross sectional area of the GB among the 3 group(P>0.1). 6) The contraction of GB revealed 1.5hr after fat meal except 1 case. 7) There was no significant differences of contracted area of GB after fat meal among the 3 group (P>0.1) 8) There was no significantly increased the thickness of GB wall after fat meal in normal control group (3.49±0.8mm) (P>0.005), There was significantly increased in acute viral hepatitis group (5.49±1.77mm) (P>0.25) and convalescent stage of acute viral hepatitis (4.0±0.84mm) (P<0.005) in that of 12 hr fasting.
