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

Inclusion Criteria: * Aged between 18 and 75 years old; * Liver cirrhosis (diagnosed by imaging, laboratory tests, clinical symptoms, or liver biopsy); * Experienced bleeding of gastroesophageal varices (GVs) (GOV1, GOV2, or IGV1) within 5 days to 1 year (bleeding lesions observed under endoscopy originating from GVs, or no other bleeding lesions except GVs were found); * Presence of spontaneous portosystemic shunts that are technically feasible for BRTO; ⑤ Willing to participate in this clinical study, comply with the study requirements, and sign the informed consent form. Exclusion Criteria: * Previously received vascular interventional therapy for preventing rebleeding of GVs; * Eligible for variceal ligation treatment of GOV1; * Non-cirrhotic portal hypertension (including regional portal hypertension); * Previously underwent surgical and interventional shunt procedures; * Presence of contraindications to endoscopic or interventional treatment; ⑥ Extensive portal vein thrombosis, cavernous transformation of the portal vein; ⑦ Massive ascites; ⑧ Concurrent advanced liver cancer or other malignant tumors with a predicted lifespan of less than 3 months; ⑨ Concurrent severe diseases of other organs such as the heart, lungs, and kidneys; ⑩ Pregnant or lactating women.
