Abstract
Portal hypertension is a serious complication of advanced liver disease. Portal pressure gradient measurement accurately determines severity of portal hypertension, prognosis, and guides medical therapy. Conventionally, interventional radiology-guided hepatic venous portal gradient measures portal pressure gradient indirectly using specialized balloon catheter. Recent advances in endoscopy have paved the novel method of endoscopic ultrasound-guided direct portal pressure gradient measurement to evaluate portal hypertension with equivalent safety in both animal models and humans studies. With the expansion of Endo-Hepatology practice, a concept of “one stop shop” is becoming more popular which is a comprehensive endoscopic approach in the evaluation of chronic liver disease. During the same endoscopic procedure, patients could be evaluated for esophageal or gastric varices, portal hypertensive gastropathy, EUS-guided elastography, EUS-guided portal pressure measurement and EUS-guided liver biopsy when suspecting advanced liver disease or diagnosis remains uncertain. This article focuses on the overview of portal hypertension and EUS-guided interventions such as EUS-guided portal pressure measurement, EUS-guided elastography and EUS-guided liver biopsy in the evaluation of individuals with advanced liver disease.
