increases the risk for liver cancer. Few studies have been conducted on the risk for liver cancer in patients with primary biliary cirrhosis; however, one study reported an incidence of 2.3%. Approximately 4% of patients with cirrhosis caused by hepatitis C develop liver cancer. In Asia, about 15% of people who have chronic hepatitis B develop liver cancer, but this high rate is not seen in other parts of the world. One Italian study that followed a group of hepatitis B patients for 11 years found no liver cancer over that period of time.

Definition
A peritoneovenous shunt refers to the surgical insertion of a shunting tube to achieve the continuous emptying of ascitic fluid into the venous system.
Purpose
Ascites is a serious medical disorder characterized by the pathological accumulation of fluid in the peritoneal cavity, the smooth membrane that lines the cavity of the abdomen and surrounds the organs. Ascites is usually related to acute and chronic liver disease (cirrhosis) and to a lesser degree, to malignant tumors arising in the ovary, colon, or breast. Ascites may also be associated with chronic kidney disease and congestive heart failure. The formation of ascitic fluid results from the interplay of three factors: abnormally high pressure within the liver or the veins draining into the liver (portal hypertension); abnormally low amounts of albumin in the blood (hypoalbuminemia); and changes in sodium and water excretion by the kidneys.
