This study compares two endoscopic ultrasound-guided treatments for gastric varices, which are enlarged veins in the stomach that can bleed. Both treatments use small coils placed into the varix. One group will receive coils with cyanoacrylate medical glue, and the other group will receive coils with absorbable gelatin sponge.
The purpose of the study is to determine whether absorbable gelatin sponge with coils is not worse than cyanoacrylate glue with coils for closing off gastric varices, and to compare safety outcomes. Participants will be randomly assigned to one of the two treatment groups. Participants and outcome assessors will not know which treatment was used, but the doctor performing the procedure will know.
After the procedure, participants will be followed for up to 12 months. Follow-up may include clinical assessments, questionnaires about health and quality of life, CT imaging shortly after the procedure, and repeat endoscopic ultrasound assessments to evaluate whether the gastric varix has been successfully treated.
