[Epidemiology and natural history of cirrhosis].

The cirrhosis prevalence in the whole French population can be estimated between 2000 and 3300 cases/million of individuals. Alcoholism, hepatitis C virus and non alcoholic fatty liver disease are the three most common causes of cirrhosis in France. About 40% of patients with cirrhosis have compensated cirrhosis and are asymptomatic over long period of 1 to 10 years. Decompensation of cirrhosis was considered when a patient first developed one of the mayor complications of the disease (ascites, jaundice, encephalopathy or gastrointestinal haemorrhage). After the first decompensation, the incidence of death is about 10% by year, in the absence of hepatic transplantation. The mortality of patients with cirrhosis and acute varicose bleeding has greatly decreased over the past 2 decades in concurrence with an early and combined use of pharmacological and endoscopic therapy, but hepatocellular carcinoma is the most frequent life threatening complication.
