Registration Number
NCT06106971
Lead Sponsor
Kaohsiung Veterans General Hospital.
Brief Summary

The goal of this randomized controlled trial is to compare the rebleeding rate in cirhotic patients with gastric variceal bleeding receiving balloon-occluded retrograde transvenous obliteration and endoscopic tissue glue injection. The main questions it aims to answer are:

* Recurrent gastric variceal bleeding

* Further decompensation of liver cirrhosis

Participants will receive balloon-occluded retrograde transvenous obliteration and endoscopic tissue glue injection. Researchers will compare balloon-occluded retrograde transvenous obliteration and endoscopic tissue glue injection to see if the rebleeding rate associated with balloon-occluded retrograde transvenous obliteration is lower than that associated with endoscopic tissue glue injection.

Detailed Description

Variceal bleeding is a severe complication of portal hypertension. Gastric variceal bleeding (GVB) is more severe than bleeding from esophageal varices. Gastric varices also have a higher risk of rebleeding than esophageal varices. Previous studies showed that endoscopic injection of cyanoacrylate was superior to endoscopic variceal ligation in the management of gastric variceal bleeding. Another study showed that transjugular intrahepatic portosystemic shunt had a lower rebleeding rate than endoscopic cyanoacrylate injection. However, transjugular intrahepatic portosystemic shunt (TIPS) is more invasive and carries a risk of development of hepatic encephalopathy and is usually preserved for uncontrolled variceal bleeding. Therefore, endoscopic cyanoacrylate injection is recommended as the treatment of choice for GVB. Balloon-occluded retrograde transvenous obliteration (BRTO) is a new therapy for gastric variceal bleeding. However, BRTO is associated with increased portal pressure and worsening of ascites, hepatohydrothorax, and esophageal varices. There are only a few retrospective studies comparing BRTO and endoscopic cyanoacrylate injection in the prevention of recurrent gastric variceal bleeding.
