[Non-invasive evaluation and prediction of portal hypertension: focusing on disease progression and outcome]

Portal hypertension is a major complication of cirrhosis. The current gold standard for diagnosis is the hepatic venous pressure gradient, but it possesses limitations such as invasiveness. In recent years, non-invasive tests have made significant progress in terms of evaluating and prognostication of portal hypertension. This article reviews the diagnostic value and related research advancements of different non-invasive tests in assessing portal hypertension in patients with cirrhosis.
