Abstract
Prospective study of gallbladder wall thickness by utrasonography was performed in 38 patients of acute viralhepatitis and 50 normal subjects as a control group from June 1983 to April 1984. The results were as follows; 1.In normal population, the range of gallbladder wall thickness is from 1mm to 3mm with peak incidence in 2mm(66%,33 case). Mean thickness of gallbladder wall is about 1.9±0.6mm. 2. In acute viral hepatitis, the range ofgallbladder wall thickness is from 2mm to 8mm with peak incidence in 3mm(34%, 13 case), second peak in 4mm (29%,11 case). Mean thickness of gallbladder wall is about 3.6±1.6mm, which is thicker than normal with statisticalsignifiance. (p<0.005) 3, In acute viral hepatitis , the mean thickness of glabladder wall is about 4.4±1.8mm inthe group of SGOT/ SGPT level above 400 IU, and 2.8±0.8mm in the group of SGOT/SGPT level below 400 IU. Thisdifference is significant statistically. (p<0.05)
