Experimental study of the evaluation of liver function on the opposite side during portacaval anastomosis and ligation of the left portal branch.
BACKGROUND
Hepatocellular carcinoma is likely to accompany liver cirrhosis in which the portal pressure increases with portasystemic shunt. When portal tumor thrombus is present in the primary bifurcation, blood flow differs between the thrombolic lobe and the non-thrombolic lobe. In those cases, it is difficult to evaluate exactly residual liver function by conventional test. Therefore, the following studies were performed.


METHODS
Adult mongrel dogs are divided into a control group (C group), group undergoing ligation of the left portal branch (PL group), group undergoing portacaval anastomosis (PCS group) and group undergoing both ligation of the left portal branch and portacaval anastomosis (PL+PCSgroup)(n=5). ICG-R15 and MEGX15 in peripheral venous blood and right hepatic venous blood were determined. Mitochondrial metabolic capacity (adenosine triphosphate level, energy charge) was measured by high-performance liquid chromatography using liver biopsied specimens.


RESULTS
The MEGX ratio (right hepatic venous blood MEGX15/peripheral venous blood MEGX 15) positively correlated with energy charge in the right hepatic lobe.


CONCLUSIONS
In evaluating liver function of the right hepatic lobe during portacaval shunt and the left portal branch ligation, the MEGX ratio may sensitively reflect the mitochondrial function.
