Efficacy and Safety of Contrast EUS-Guided Tissue Glue/Coil Devascularization vs. BRTO for Preventing Recurrent Gastric Variceal Bleeding

Under linear array endoscopic ultrasound (EUS), puncture GVs with a 19G/22G needle, deploy coils, and inject 1-2ml tissue glue until blood flow in GVs disappears (or inject glue directly if coils are unsuitable). Treat moderate-to-severe esophageal varices (EVs) with band ligation during or after the procedure.

Establish vascular access via the femoral or internal jugular vein, occlude gastrorenal shunts with a balloon catheter, and inject sclerosant foam. Treat moderate-to-severe EVs with band ligation within 5 days post-procedure.
