This presentation explores biliary cirrhosis, a chronic liver disease characterized by progressive destruction of bile ducts, leading to impaired bile flow and liver damage. The report comprehensively examines the different types of biliary cirrhosis, including primary biliary cholangitis (PBC) and secondary biliary cirrhosis (SBC), detailing their distinct etiologies and pathophysiological mechanisms. We will delve into the diagnostic approaches, including the role of biochemical markers, imaging techniques, and liver biopsies, to understand how these tools are utilized for accurate diagnosis. Moreover, the report will address the therapeutic strategies, which encompass pharmacological interventions such as ursodeoxycholic acid and immunomodulatory agents, along with the importance of lifestyle modifications and potential liver transplantation.
