Esophageal Variceal Ligation (EVL)

It is often used for primary prevention of esophageal varices with high-risk bleeding signs, or for acute hemostasis and secondary prevention after bleeding. Whether to consider it depends on the degree of varices and red signs, previous bleeding history, response to drug and endoscopic treatment, liver function and coagulation status, and whether it is suitable for other regimens (such as non-selective β-blockers, transjugular intrahepatic portosystemic shunt).
