Endoscopic Ruler for the Assessment of Variceal Bleeding Risks (CHESS2005)

Endoscopic Ruler for the Assessment of Variceal Bleeding Risks in Portal Hypertension (CHESS2005): A Prospective Multicenter Trial

The presence of varices is a serious complication of portal hypertension in liver disease. To prevent variceal haemorrhage, screening and surveillance aims to detect high-risk varices related to varices size and determine the need for primary prophylaxis. Varices size evaluated by endoscopists might not be perfect reference, influenced by experience and machine. Endoscopic ruler is a novel tool to measure the varices size under the endoscopy. The investigators aim to evaluate the bias of varices size between endoscopists and endoscopic ruler as the reference.
