Hepatology
Summary
Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Although traditionally considered a sub-specialty of gastroenterology, rapid expansion has led in some countries to doctors specializing 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. More than two billion people have been infected with hepatitis B virus at some point in their life, and 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 mortality, the former is second only to smoking among known agents causing cancer. With more widespread implementation of vaccination and strict screening before blood transfusion, lower infection rates are expected in the future. In many countries, however, overall alcohol consumption is increasing, and consequently the number of people with cirrhosis and other related complications is commensurately increasing.
As for many medical specialties, patients are most likely to be referred by family physicians (i.e., GP) or by physicians from different disciplines. The reasons might be:
Drug overdose. Paracetamol overdose is common.
Gastrointestinal bleeding from portal hypertension related to liver damage
Abnormal blood test suggesting liver disease
Enzyme defects leading to bigger liver in children commonly named storage disease of liver
Jaundice / Hepatitis virus positivity in blood, perhaps discovered on screening blood tests
Ascites or swelling of abdomen from fluid accumulation, commonly due to liver disease but can be from other diseases like heart failure
All patients with advanced liver disease e.g. cirrhosis should be under specialist care
To undergo ERCP for diagnosing diseases of biliary tree or their management
Fever with other features suggestive of infection involving mentioned organs.
