Cirrhosis is a common diffuse liver disease that produces diffuse proliferation of liver fibrous tissue based on extensive degeneration and necrosis of hepatocytes and the formation of regenerative nodules and pseudobullets, resulting in the destruction of normal liver lobular structures and vascular anatomy. The onset of cirrhosis is often insidious, and there may be no specific symptoms and signs in the early stage. The decompensated stage of cirrhosis can have many serious complications such as hepatic encephalopathy, hemorrhage, infection, etc., with high death rate and great danger. The majority of cirrhosis has a history of hepatitis B virus or long-term heavy alcohol consumption. Early cirrhosis and mid- to late-stage cirrhosis are fundamentally different. Early cirrhosis can be reversed or no longer progress after active prevention and treatment is relatively effective, while mid- to late-stage cirrhosis is significantly less effective than early cirrhosis and can only reduce symptoms and extend the life of patients as much as possible. Therefore, the active prevention, early detection and comprehensive treatment of cirrhosis are very important.
