Endoscopic ultrasonography - emerging applications in hepatology. Magalhães Joana,Monteiro Sara,Xavier Sofia,Leite Sílvia,de Castro Francisca Dias,Cotter José World journal of gastrointestinal endoscopy The inspection of the liver is a valuable part of the upper endoscopic ultrasonography (EUS) studies, regardless of the primary indication for the examination. The detailed images of the liver segments provided by EUS allows the use of this technique in the study of parenchymal liver disease and even in the diagnosis and classification of focal liver lesions. EUS has also emerged as an important tool in understanding the complex collateral circulation in patients with portal hypertension and their clinical and prognostic value. Recently, EUS-guided portal vein catheterization has been performed for direct portal pressure measurement as an alternative method to evaluate portal hemodynamics. In this review, the authors summarize the available evidence regarding the application of EUS to patients with liver diseases and how we can apply it in our current clinical practice. 10.4253/wjge.v9.i8.378
