Ascites: tips on diagnosis and management.
Clinical evaluation and diagnostic paracentesis with estimation of the serum-ascitic albumin gradient (SAAG) is the most important step in identifying the etiology of ascites. At a level of 1.1 g/dl, SAAG, accurately (96.7%) differentiate portal hypertension from nonportal hypertension-associated ascites. The majority of patients with ascites (>80%) have portal hypertension associated etiology mainly, liver cirrhosis. Approximately 90% of patients with ascites complicating cirrhosis respond to salt restriction and diuretics. The remainder (10%),have refractory ascites which commonly respond well to large volume paracentesis (LVP). Asymptomatic complications occurring in patients treated with LVP may not necessitate treatment. Other alternative methods for treatment of refractory ascites include: ascitic fluid recirculation (AR), peritoneovenous shunting (PVS),transjugular intrahepatic portosystemic stent-shunting (TIPS) and orthotopic liver transplantation (OLT).
