Cirrose e Complicações 2006
Ascites is a major complication of cirrhosis,1 occurring in 50% of patients over 10 years of follow-up.2 The development of ascites is an important landmark in the natural history of cirrhosis as it is associated with a 50% mortality over two years,2–5 and signifies the need to consider liver transplantation as a therapeutic option.3 The majority (75%) of patients who present with ascites have underlying cirrhosis, with the remainder being due to malignancy (10%), heart failure (3%), tuberculosis (2%), pancreatitis (1%), and other rare causes.6 The true prevalence and incidence of cirrhosis of the liver and its complications in the UK are unknown. Mortality from cirrhosis has increased from 6 per 100 000 population in 1993 to 12.7 per 100 000 population in 2000.7 Approximately 4% of the general population have abnormal liver function or liver disease8 and approximately 10–20% of those with one of the three most common chronic liver diseases (non-alcoholic fatty liver disease, alcoholic liver disease, and chronic hepatitis C) develop cirrhosis over a period of 10–20 years. With a rising frequency of alcoholic and non-alcoholic fatty liver disease, a huge increase in the burden of liver disease is expected over the next few years8 with an inevitable increase in the complications of cirrhosis. There have been several changes in the clinical management of cirrhotic ascites over recent years, and the purpose of these guidelines is to promote a consistent clinical practice throughout the UK.
