NCT07049146
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.
NCT06670157
A single-arm exploratory clinical study design was used to evaluate the safety and efficacy of a "modified sandwich injection" of tissue glue assisted by a detachable clip for the treatment of gastric varicose veins.
NCT06370169
The standard treatment of bleeding gastric varices is obliteration with placement of coil and glue. Our study will evaluate the efficacy of EUS guided coil as primary prophylaxis for high-risk gastric varices. All procedures will be performed with patient under deep sedation or general anaesthesia under the supervision of an anaesthesiologist.
NCT06122792
The prevalence of gastric varices is approximately 20%. It is important to note that gastric varices tend to bleed more severely, have a higher morbidity and mortality rate, and have a 35% to 90% risk of rebleeding after the cessation of acute hemorrhage. Because of the relatively low prevalence of gastric varices, the existing clinical studies have many deficiencies, and there is much controversy in the academic community, the optimal treatment and prevention strategies for gastric varices have not yet been fully defined. In the last few years, important advances have been made in the treatment and prevention of gastric variceal bleeding in patients with cirrhosis. Experts agree that the combination of pharmacological and endoscopic injection of tissue adhesives should be the first line of therapy in the acute bleeding episode from isolated gastric varices (IGV1) or type 2 gastroesophageal varices (GOV2) varices; whereas transjugular intrahepatic portosystemic shunt (TIPS) is considered a rescue therapy. TIPS has been shown to effectively prevent variceal rebleeding but with a potential increase in the incidence of hepatic encephalopathy and/or liver failure. In this sense, a recent randomized controlled trial (RCT) in fundal variceal bleeding showed that an early TIPS, performed during the first 5 days after patient admission resulted in a significant decrease in failure to control bleeding and early and late rebleeding. However, the study was conducted for 4 years and only included 25 patients. Due to insufficient sample size, it was unable to reflect whether priority TIPS can bring survival benefits to patients with gastric variceal bleeding. Therefore, there is an urgent need for multi-center clinical studies with large samples to provide high-quality evidence in the field of prioritizing TIPS for the treatment of acute gastric variceal bleeding. The present study aims to compare the preemptive TIPS (performed during the first 72 hours after endoscopy) with standard second prophylaxis (endoscopic injection of tissue adhesives plus carvedilol) for patients with acute bleeding from gastric varices (IGV1 or GOV2). The primary outcome will be a 6-week mortality from inclusion.
NCT06106971
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.
NCT03438916
Background: Standardization and new therapeutic treatments of variceal bleeding has significantly reduced the mortality the last 25 years, but there is still a high 6-week mortality around 15-20% and 1-year mortality of about 40%. Cirrhotic patients without prophylactic treatment suffer a risk of 60% of re-bleeding within the first year after the first bleeding episode. Variceal ligation and NSBB are the standard therapy as secondary prophylaxis, while only non-selective beta-blocker (NSBB) is offered as first-line therapy in primary prophylaxis. If portal pressure is reduced to a value below 12 mmHg or by 20% (10% if assessed by intravenous administrations), the risk of bleeding is substantially reduced, but not all patients respond to the treatment with propranolol (40-50%). Hence, patients who are non-responders to NSBB should be offered alternative treatment with e.g. carvedilol, which is a combined alpha-beta-receptor blocker or endoscopic band ligation. Currently, the response to NSBB is assessed invasively during a liver vein catheterization (LVC). Unfortunately, only a few centres in the world can perform this procedure and there are no reliable non-invasive alternatives to assess the respond to NSBB, which is of extreme importance, since non-responders have three fold increased risk of a new variceal bleeding episode. Aim: In general the aim of the project is to develop faster and non-invasive methods to evaluate portal hypertension and individual pharmacological response of NSBB in patients with cirrhosis. Furthermore, we expect to detect changes in liver and spleen stiffness as measured by MR-Elastography (MRE) after NSBB and that these depend on the drug-related effects on portal pressure. Study design and patients: 39 patients with cirrhosis and esophageal varices that require NSBB (propranolol) treatment. Patients are assessed with LVC, MR-scans, echocardiography and biochemical tests. LVC is the gold standard method to test if patients respond to propranolol treatment. At visit 1. the response to NSBB is defined as a reduction of HVPG ≥10%, or to a HVPG\< 12mmHg after intravenous NSBB administrations during LVC. MRI-scan with intraveneus NSBB administration is performed at visit 2. Minimum 5 days of NSBB wash out between visit 1 and 2.

This study aimed to clarify the safety of anticoagulant therapy after glue injection for cirrhotic variceal bleeding patients with portal vein thrombosis.
