Ascites is a major complication of cirrhosis
The development of ascites is an important landmark in the natural history of cirrhosis as it is associated with a 50% mortality over two years,and signifies the need to consider liver transplantation
as a therapeutic option.
Firstline treatment of ascites should be spironolactone
alone, increasing from 100 mg/day to a dose of 400 mg/day.
If this fails to resolve ascites, frusemide should be added in a dose of up to 160 mg/day, but this should be done with careful biochemical and clinical monitoring.
Patients with large or refractory ascites are usually initially managed by repeated large volume paracentesis
You must consult a gastroenterologist
surgeon and explore the possibility of liver transplant,which is the most ideal treatment,if it is possible in your father.
