Hepatology

n. study of liver, field of medicine that deals with the liver and its treatment

Hepatology is the branch of medicine that incorporates 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 of gastroenterology, rapid expansion has led in some countries to doctors specialising solely on this area, who are called hepatologists.
