Brion and Avni have compared the clinical estimation of liver size by the liver span and the size of its edge below the right costal margin.
Some of their results are in accordance with ours, such as the lack of differences between the measurements immediately after birth and a few days later, and the reduced size of liver edge found in our preliminary measurements in infants who were small for gestational age (Table).
It seems to us that the practical approach to the clinical estimation of liver size in the newborn should include routine measurement of liver edge in every healthy newborn infant.
