Liver cirrhosis is a severe illness, associated with multiple complications, which can lead to liver failure. One of the major complications of cirrhosis is ascites. This review describes a stepped treatment approach for the management of ascites in Japanese patients with cirrhosis. It is broadly based on the 2020 update of the Japanese clinical practice guidelines for liver cirrhosis, which is briefly compared with guidelines from Europe and the United States. Step 1 is sodium restriction at a level suitable for Japanese individuals (5–7 g/day), Step 2 is albumin treatment to counteract underlying hypoalbuminemia, Step 3 is initiation of diuretic treatment with spironolactone, followed by add‐on loop diuretic treatment at Step 4. Patients that are refractory to sodium restriction and sodium diuretics can be treated with tolvaptan (Step 5) – a vasopressin V2 receptor antagonist that is available in Japan. Patients at Steps 6 and 7 have refractory ascites and are treated with large volume paracentesis in combination with an albumin infusion. High‐dose albumin infusion (6–8 g/L) at the time of large volume paracentesis has recently become possible in Japan. Cell‐free and concentrated ascites reinfusion therapy is also an option at Step 6. Two of the treatment options at Step 7 are limited in Japan (transjugular intrahepatic portosystemic shunts are not approved, and access to liver donors is very limited), but patients can undergo a peritoneovenous shunt if no other options are available. While challenges remain in the treatment of ascites, adopting this stepwise treatment approach may improve patient outcomes.
