Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Etymologically the word Hepatology is formed of ancient Greek hepar(ηπαρ) or hepato-(ηπατο-) meaning 'liver' and suffix -logia(-λογια) meaning 'word' or 'speech'. Although traditionally considered a sub-specialty ofgastroenterology, rapid expansion has led in some countries to doctors specializing solely on this area, who are calledhepatologists.
