title: Treatment of ascites and renal failure in cirrhosis.
abstract: Ascites is a frequent complication in patients with liver cirrhosis. The accumulation of fluid in the abdominal cavity is associated with disturbances of systemic and splanchnic haemodynamics and of kidney function, which contribute to the poor prognosis of these patients. Classically, the treatment of ascites in patients with cirrhosis has been based on the combination of a sodium-restricted diet and the administration of diuretics. However, this treatment is not entirely satisfactory, since it is associated with a relatively high incidence of side-effects, and about 20% of patients hospitalized for the treatment of an episode of ascites do not respond to such therapy. In the last two decades, alternative therapies to diuretics have been introduced. PVS is an effective method of treating ascites. The high incidence of complications observed in early studies may be reduced by adequate perioperative management and careful selection of patients. The role of the PVS in the treatment of cirrhotics with ascites, however, still remains to be established. Recently, paracentesis has emerged as an alternative method of treating ascites in patients with cirrhosis. Several studies have shown that therapeutic paracentesis plus i.v. albumin infusion is more effective than conventional diuretic therapy and is associated with a lower incidence of complications. It has also been demonstrated that therapeutic paracentesis without the i.v. administration of albumin is associated with a marked increase in plasma renin activity, suggesting an impairment of effective blood volume, and with the development of hyponatraemia and/or renal failure in 20% of cases. Therefore, the i.v. administration of albumin is an essential measure in preventing the impairment of systemic haemodynamics and renal function that frequently follows the mobilization of ascites by paracentesis.
