PURPOSE: To investigate the usefulness of evaluating liver cirrhosis through the measurement of liver volume. MATERIALS AND METHODS: In a control group(20 normal subjects) and 20 cirrhotic patients, variations in liver volume before and after a meal were obtained. A case-control study was conducted between the two groups. RESULTS: In the control group, the range of increased liver volume after the meal was 67-186ml. Mean increased liver volume was 119.3ml, the range of percentage increase was 6-12% and the mean percentage increase was 9.89%. In cirrhotic patients, the range of increased liver volume after the meal was 1-20ml. Mean increased liver volume was 6.9ml, the range of percentage increase was 0-1.9% and the mean percentage increase was 0.65%. Compared with the control group, cirrhotic patients showed a much smaller increase in liver volume (p<0.01). CONCLUSION: Difference in variation of liver volume between a control group and cirrhotic patients before and after a meal can be used for the evaluation of liver cirrhosis.
