The burden of ascites in cirrhosis

Liver cirrhosis is a leading cause of morbidity and mortality worldwide, with complications such as ascites, spontaneous bacterial peritonitis (SBP), and hepatorenal syndrome (HRS) significantly worsening prognosis. This paper aims to review the pathophysiology, diagnostic approaches, and management strategies for ascites and the complication of it, emphasizing the role of portal hypertension.

We conducted a comprehensive review of the literature on liver cirrhosis, portal hypertension, ascites formation, and related complications. Existing evidence was evaluated and ranked using the GRADE system: A (high) to D (verly low). Recommendation strength was graded 1 (strong) or 2 (weak).

Portal hypertension is the key factor in ascites development. Non-invasive tools such as liver stiffness measurement (LSM) have proven to be effective in identifying patients at risk for clinically significant portal hypertension (CSPH), thus guiding treatment decisions. Carvedilol, recommended over propranolol, offers superior efficacy in reducing portal pressure. Diuretics, in combination with a moderate sodium-restricted diet, are the first-line treatment for ascites. However, refractory ascites requires advanced interventions. Spontaneous bacterial peritonitis (SBP) remains a major complication in patients with ascites, while hepatorenal syndrome - acute kidney injury (HRS-AKI) demands early recognition and timely vasoconstrictor therapy.

Liver cirrhosis and the complication of it significantly impact patient quality of life and survival. Portal hypertension is a critical driver of ascites and other complications, making early identification through non-invasive diagnostic methods essential for appropriate management. Medical treatments, including non-selective beta-blockers (NSBBs), diuretics, and advanced procedures, offer substantial benefits in controlling ascites and preventing further decompensation.
