Hepatology refers to the branch of medicine that studies and manages disorders of the gallbladder, pancreas, liver and biliary tree. It was previously considered as a subspecialty of gastroenterology, but it is now becoming recognized as a separate field of study. Clinical research in hepatology is focused on developing novel medications, such as improvements to well-established liver transplantation procedures, antiviral medicines and developing new strategies for sustenance of failing liver. The application of molecular biology methods has helped to shed light on the vulnerability to various liver problems, as well as the mechanisms of liver diseases with hereditary and viral origins. This book aims to shed light on some of the unexplored aspects of hepatology and the recent researches in this field. Those in search of information to further their knowledge will be greatly assisted by it.
