Clinical Study on the Selection of Endoscopic Varicose Disconnection Strategy Based on Natural Portal Shunt with Portal Hypertension

Group A: Spring plug combined with ECI under the guidance of endoscopic ultrasound (EUS): Spring plug was placed to limit the flow of varicose veins by EUS, and then tissue glue was injected under EUS to block the varicose veins. Group B: Titanium clip plus EUS-guided spring plug placement to limit the flow combined with ECI: After partial titanium clip flow limitation under endoscopy, spring coil combined with tissue glue injection was placed in the varicose veins by judging the inflow and outflow tracts under the guidance of ultrasound (EUS).
