Hepatocellular Carcin The development of ascites is the final consequence of a series of anatomic, pathophysiologic, and biochemical abnormalities occurring in patients with cirrhosis. The two older theories of ascites formation, the underfill theory [ 2] and the overflow theory [ 3 ], appear to be relevant at different stages of the natural history of cirrhosis [ 4 ]. Cirrhosis is a late-stage result of liver disease and its complications. Decompensating events include ascites, sepsis, variceal bleeding, encephalopathy, and non-obstructive jaundice.

This permanent damage or scarring of the liver leads to blockage of blood flow within the liver. Diagnosis. Ethanol metabolism in the liver is carried out mainly by two enzymes: Alcohol dehydrogenase. Core Tip: Lymphatic dysfunction appears to play a significant role in the pathophysiology of advanced cirrhosis.Sustained portal hypertension, neurohormonal changes, and low-grade chronic inflammation have been implicated in causing lymphatic dysfunction in advanced cirrhosis, leading to worsening of ascites, lymphedema, and abnormal lipid transport; it also results in increased susceptibility . Cirrhosis refers to the replacement of normal liver tissue with non-living scar tissue. In very young children, cirrhosis is most often caused by a genetic (inherited) liver problem such as biliary atresia. A role for toxic oxygen radicals in the pathogenesis of alcoholic liver injury has also been suggested and the demonstration that patients with cirrhosis are more likely to generate greater amounts of oxygen radicals following ethanol exposure as a result of genetic polymorphisms supports this hypothesis (Naassila et al., 2002).

Cirrhosis is a condition caused by chronic damage to the liver, most commonly due to excessive alcohol consumption, nonalcoholic fatty liver disease, or hepatitis C infection. This volume is based on the Proceedings of the International Symposium held in Dresden, Germany, in October 2007 under the auspices of the prestigious Falk Foundation. leading to progressive loss of liver function. Pathogenesis. A chronic progressive disease of the liver characterized by diffused damage to cells with fibrosis and nodular regeneration. As necrotic tissue yields to fibrosis, this disease alters liver structure and normal vasculature, impairs blood and lymph flow, and ultimately causes hepatic insufficiency. Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, and end-stage liver disease, is the impaired liver function caused by the formation of scar tissue known as fibrosis due to damage caused by liver disease. The pathogenesis of toxic liver disease 1. PowerPoint Presentation Last modified by: 1 Based on histology, pathogenesis, and natural history, the NAFLD disease spectrum is characterized by excess fat deposition in the liver that is unassociated with injury or inflammation (isolated steatosis or nonalcoholic fatty liver [NAFL]) on one end and . Hepatocellular carcinoma, a type of liver cancer commonly caused by cirrhosis, starts in the liver tissue itself.
