The goal of this clinical trial is to compare the effectiveness of EUS-guided tissue glue/coil injection and BRTO in preventing rebleeding of gastric varices (GVs) in patients with portal hypertension and GVs (including those with esophageal varices, ascites, or hepatic encephalopathy). The main questions it aims to answer are:
Is the 1-year all-cause rebleeding rate of EUS-guided tissue glue/coil injection for GVs non-inferior to that of the BRTO group? Does EUS-guided tissue glue/coil injection differ from BRTO in the incidence of decompensated portal hypertension events (variceal bleeding, overt hepatic encephalopathy, ascites) and survival rate post-treatment?
Researchers will compare patients randomized 1:1 to the EUS-guided tissue glue/coil injection arm vs. the BRTO arm to see if there are differences in rebleeding rates and complications.
Participants will:
Receive EUS-guided tissue glue/coil injection or BRTO. Take carvedilol long-term (if no contraindications) to reduce portal pressure. Undergo follow-up assessments at 1, 3, 6, and 12 months ±7 days.
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.
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;
Parallel
EUS-guided tissue glue/coil injection
Procedure/SurgeryUnder 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.
BRTO
Procedure/SurgeryEstablish 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.
One-year all-cause rebleeding rate
The rate of upper gastrointestinal bleeding occurring within one year after the operation, regardless of the cause
