The field of hepatology is concerned with the study of the liver, biliary tree, gallbladder and pancreas, and their clinical conditions. Some of the diseases affecting the hepatobiliary system include Aagenaes syndrome, Budd-Chiari syndrome, Crigler-Najjar syndrome, Mirizzi's syndrome, HELLP syndrome, Alagille syndrome, etc. The diseases arising due to alcohol consumption and viral hepatitis are the common conditions that are under the scope of this study. There has been a rise in cases of cirrhosis and related complications. Liver function tests detect enzymes in blood which normally are most abundant in liver tissue, such as serum albumin, serum globulin, aspartate transaminase, alanine transaminase, etc. An examination of these levels aids in the diagnosis of liver conditions. The objective of therapy in hepatology is to slow the progression of the disease. This is done with anti-viral medications, steroid-based drugs, medications such as ursodeoxycholic acid, etc. Liver transplantation is an effective treatment for acute or chronic liver conditions with the potential to cause severe and irreversible liver dysfunction. This book explores all the important aspects of clinical hepatology in the modern day. It strives to provide a fair idea about hepatological disorders and to help develop a better understanding of the latest advances in their clinical management. With state-of-the-art inputs by acclaimed experts of hepatology, this book targets students and professionals.
