  • Study of Liver Volume Measurement and Its Clinical Significance in Cirrhotic Patients with Portal Hypertension

    Objective To study the value of the clinical application of stereography and measurement of liver volume in cirrhotic patients with portal hypertension. Methods By use of the personal computer and the software of threedimensional reconstruction and measurement system of liver faultage photograph, the liver volume in vivo was successfully measured and the threedimensional image of the liver rebuilt in 46 posthepatitic cirrhotics who were selected for orthotopic liver transplantation and in 30 noncirrhotic controls, and comparison with the reference volume of recipient liver was obtained by means of water deplacement after transplantation. Results The liver volume of cirrhotic patients with portal hypertension measured by software and water deplacement was (983.33±206.11) cm3, and (904.93±209.56) cm3 respectively. Comparison by means of linear regression analysis between volume measurement on threedimensional reconstruction software and reference volume showed a nearly ideal correlation coefficient(r=0.969,P<0.01), the average error was 8.66%.The average of liver volume in controls was (1287.00±96.18) cm3, and was positively correlated to the height,weight and body surface area (r=0.845,0.833,0.932 respectively,P<0.01),and was different from that of cirrhotics. Liver volume of cirrhoitic patients with portal hypertension was related to their ChildPugh classification. The liver volume of patients in Child C group was significantly smaller than that of patients of Child B group, and was significantly correlated with Alb (r=0.496, P<0.01) and TBIL(r=-0.493, P<0.01),PT(r=-0.517, P<0.01), but was not significantly correlated with ALT(r=0.206,Pgt;0.05),portal pressure(r=-0.093,P=0.539) and portosystemic shunt index (r=0.044,P=0.769). Conclusion The volume measurement of the liver by the threedimensional software is relatively accurate. Liver volume of cirrhotic patients with portal hypertension was significantly related to their liver function,and can reflect the liver reserve function.
