Bleeding risk of variceal band ligation in extrahepatic portal vein obstruction is not increased by oral anticoagulation.

Background And Objectives: Noncirrhotic nontumoral extrahepatic portal vein obstruction (EHPVO) is the second leading cause of portal hypertension (PHT) and is mainly related to prothrombotic disorders. Patients with EHPVO often require prolonged oral anticoagulation therapy (OAT) together with variceal band ligation (VBL) to prevent thrombosis recurrence and PHT-related bleeding, respectively. The benefit-risk balance of VBL in this context remains unknown.
