Cirrhosis is characterized by changes in the basic structure with the development of liver fibrosis and nodule formation. Fibrosis is an irreversible change, causing replacement of liver cells without cell function. Ultimately it is the reaction of the liver to external aggression. Often occurs in adults and is more common among 50-60 years old and is an important cause of death. Fibrosis can lead to circulatory changes leading to portal hypertension and esophageal varices, whose disruption can cause severe bleeding. You can still progress to liver failure.

Cirrhosis is the leading cause of death from liver nature, excluding tumors. Its main causes are alcoholism and chronic hepatitis (types B and C). Also can occur as a complication of obstruction of bile ducts, some chronic heart disease (congestive heart failure) or due to drug intoxication. Other possible causes are: schistosomiasis, autoimmune disease, Wilson's disease, porphyria and hematocromatose.

[...] Primary malignant liver tumors generally arise during the evolution of chronic liver changes. Tumors can also be secondary, represented by metastasis from other tumors located in the digestive tract, lung or breast. The very malignant tumor of the liver is the hepatoma or hepatocellular carcinoma. It is currently one of the common tumors affecting man, being related to hepatitis (types B and and cirrhosis. Your risk increases with age. Clinical manifestations of liver tumors are poor and can sometimes be pain. Physical examination palpa up abdominal mass. [...]


[...] Ascites can occur. The pseudocyst is a local training with high concentration of pancreatic enzymes and is due to obstruction of small pancreatic ducts. After clinical examination, the patient must undergo radiological examinations. The radiograph of the abdomen seeks to show calcifications. CT scans can show small calcifications and cysts. The dosage of amylase is generally normal. The secretin test to assess pancreatic function may be useful. Treatment is symptomatic aiming relieve pain, control of malabsorption syndrome and diabetes. In the treatment of pseudocyst or abscess may be the need for surgical intervention. [...]


[...] Treatment generally is clinical, symptomatic, and in the acute forms may need intensive care. Chronic pancreatitis can occur after several episodes of acute pancreatitis. About 20% of cases occur in the elderly and is due to atrophy of the pancreas and is also related to smoking and obesity. There is a pancreatic fibrosis process with marked loss of islets of Langerhans. Progresses to atrophy of the parenchyma and pathological features two ways: pancreatitis with calcification and obstructive pancreatitis. The main causes of chronic pancreatitis are calcifying: alcoholism, hyperlipidemia, hypercalcemia, senility and called idiopathic. [...]
