  • Title: Morphometry of liver parenchyma in needle biopsy specimens from patients with alcoholic liver disease: preliminary variables for the diagnosis and prognosis of cirrhosis.
    Author: Ryoo JW, Buschmann RJ.
    Journal: Mod Pathol; 1989 Jul; 2(4):382-9. PubMed ID: 2668943.
    Abstract:
    The diagnosis of liver cirrhosis depends on assessing fibrosis and architectural alterations of the liver. In a needle biopsy specimen the connective tissue is often inadequately sampled, which leads to an uncertain diagnosis. Parenchymal features alone are currently insufficient. We, therefore, carried out a comprehensive morphometric study to detect parenchymal structures that may be useful in the diagnosis and prognosis of cirrhosis. Five human liver biopsy specimens were selected from each of four alcoholic disease groups: fatty liver, alcoholic hepatitis, cirrhosis with greater-than-5-yr survival, and cirrhosis with less-than-2-yr survival. Volume fractions (Vv) and surface densities (Sv) were determined stereologically for parenchymal and hepatocellular compartments in electron micrographs. The differences between noncirrhosis and cirrhosis were (a) a doubling of the Vv of parenchymal interstitial space, (b) a nearly 25% increase in the Sv of hepatocyte plasma membrane, (c) a nearly 50% increase in the Sv of hepatocyte RER, and (d) a decrease in the Sv of the outer mitochondrial membrane. The significant difference between the greater than 5-yr and the less than 2-yr survivors of cirrhosis was the marked decrease in hepatocyte nuclear Vv in the latter group. Statistical analysis of our data showed that optimal sampling is achieved with as few as three micrographs from one block of tissue per biopsy specimen.
