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.

Diseases and complications related to viral hepatitis and alcohol are the main reason for seeking specialist advice. One third of world population has been infected with Hepatitis B virus at some point in their life. Although most of them would clear the virus from the body, approximately 350 million have become persistent carriers. Up to 80% of liver cancers can be attributed to either hepatitis B or Hepatitis C virus. In terms of number of mortality, the former is second only to smoking among known agents causing cancer. Hopefully, widespread implementation of vaccination and strict screening before blood transfusion are going to lower the infection rate in future.

However in many countries overall alcohol intake is on the rise and as one can expect, number of people with cirrhosis and other related complications are increasing.

Scope of the specialty

As for many medical specialties, patients are most likely to be referred by family physicians( i.e. GP) or by doctors from different disciplines. The reasons might be:

History

Evidence from autopsies on Egyptian mummies suggest that liver damage from parasitic infection Bilharziasis was widespread in the ancient society.[1] It is possible that Greeks might be aware of liver's ability to exponentially duplicate as illustrated by Prometheus story. However knowledge about liver diseases in antiquity was some what sketchy. Most of the important advances in the field were made in last 50 years.
