Liver and Spleen Elastography for Screening High-Risk Esophageal Varices in Compensated Advanced Chronic Liver Disease under the Baveno VII Framework: A Scoping Review with Evidence Mapping on Variceal Risk Stratification and the Grey Zone

This scoping review aims to map the existing evidence on liver and spleen elastography for variceal risk stratification (including high-risk esophageal varices, clinically significant portal hypertension, and decompensation) in patients with compensated advanced chronic liver disease (cACLD) under the Baveno VII framework. We will identify research gaps, particularly regarding the "grey zone" of liver stiffness and the lack of consensus on spleen stiffness measurement cut-offs.
