Cirrhosis
Description
An in-depth report on the causes, diagnosis, treatment, and prevention of cirrhosis
Ascites
Nearly all patients with ascites (fluid accumulation in the abdomen) can benefit from the following measures:
-
Abstaining from alcohol. (Sometimes abstaining from alcohol is enough to reverse this complication.)
-
Restricting salt.
-
Taking diuretics, usually spironolactone (Aldactone) and furosemide (Lasix). Previously, spironolactone was usually given alone, but experts now use it by itself only in patients with minimal fluid buildup. Patients should be monitored carefully for excessive and too rapid fluid loss, which can set off complications, including hypokalemia (dangerously low potassium levels), kidney failure, or encephalopathy. Weight loss from diuretics usually should not exceed 1 - 2 pounds per day, but there is no limit for patients with massive swelling.
Doctors often recommend bed rest for patients with ascites, but many experts believe this is not necessary and studies do not support its benefits. Restricting fluid is not usually necessary unless sodium levels in the blood are very low.
Treatment for Recurring or Refractory Ascites
Patients with recurring ascites or ascites that does not respond to standard diuretics after a month may require procedures to reduce fluid.
Large-Volume Paracentesis.
Large-volume paracentesis is the current standard procedure and involves the following:
-
Large volumes of fluid are removed through a tube in the abdomen. Research indicates that 4 - 6 liters are usually effective and safe.
-
Albumin (protein) may be administered intravenously. This helps prevent a sudden drop in blood flow in the arteries. One study suggested that terlipressin, a drug that constricts blood vessels, may be as effective.
-
If the ascites does not respond to treatments, paracentesis may need to be repeated every 2 weeks or more frequently, and up to 10 liters may need to be removed.
Patients who need this procedure are probably not complying with dietary requirements.
Transjugular Intrahepatic Portosystemic Shunt (TIPS).
Studies have been mixed on whether transjugular intrahepatic portosystemic shunt (TIPS) improves survival without transplantation compared to large-volume paracentesis. An important 2003 study reported that although TIPS reduced the number of paracenteses, there was no improvement in survival rates. In addition, patients who were given TIPS had a higher risk for encephalopathy than those given large-volume paracentesis. In general, TIPS should be a second-line option for ascites that does not respond to diuretics.
Peritoneovenous Shunting.
Peritoneovenous shunting is an older, more invasive procedure, involving insertion of a tube, or shunt, under the skin that routes the fluid from the abdomen into the jugular vein. The procedure can have serious complications, including infection, blood clots, encephalopathy, and rupture of blood vessels in the esophagus. It is now generally reserved for patients who are not candidates for repeat paracentesis or liver transplantation.
Treatment of Hepatorenal Syndrome
Hepatorenal syndrome can occur in patients with ascites. This is a life-threatening condition in which the kidneys fail in trying to compensate for altered blood flow in the liver. Studies suggest that terlipressin may be an effective treatment in combination with albumin for hepatorenal syndrome.
Investigational Drugs
Researchers are testing certain drugs that may redress the imbalances in circulation that lead to portal hypertension and ascites. Of particular interest are drugs called nonpeptide vasopressin antagonists, also referred to as aquaretics. They may reverse the dilation in blood vessels that lead to salt and fluid retention.
Liver Transplantation
The prognosis for patients with ascites is poor, even with intensive procedures. Liver transplantation should be considered for patients when ascites does not respond to treatments and when poor liver function or other complications, such as peritonitis or kidney failure, are present.
