Ascites is the most common complication of cirrhosis leading to hospitalization. (Ascites marks a threshold in the nature of the underlying liver disease and is associated with a 50% mortality rate within 3 years.)
- Standard initial therapy for portal hypertensive ascites is salt restriction. (Hyponatremia is common among cirrhotic patients with ascites, and rapid correction is undesirable because cirrhotic patients are particularly at risk for central pontine myelinolysis.)
- Refractory ascites (immutable to sodium restriction, maximum doses of diuretics, and paracentesis) is the hallmark complication of type II HRS and indicates increased disease severity.
- When patients become refractory to maximum standard medical therapy, the 6-month mortality rate is 21%.
- Therapeutic options for patients are limited and include serial paracentesis, liver transplantation, transjugular intrahepatic shunt (TIPS) placement, and peritoneovenous shunt.
- Although current practice is to replace albumin when ascitic fluid is drained, this practice is not well supported by randomized prospective trials.
- Infections (bacterial translocation from the bowel) of ascitic fluid are common.
