Trial summary

Gastric varices (GV) are present in around 20% of patients with cirrhosis. Bleeding from GV accounts for 10-20% of all variceal bleeding. For the prevention of gastric variceal bleeding, TIPS or BRTO as firstline treatments were suggested. No randomized trials have compared BRTO with other therapies. Read more about this study

Official title: Interventional Devascularization Plus HVPG-Guided Carvedilol Therapy vs TIPS for the Prevention of Gastric Variceal Rebleeding in Patients With Liver Cirrhosis: A Prospective, Randomized, Controlled Trial

Gastric varices (GV) are present in around 20% of patients with cirrhosis. Bleeding from GV accounts for 10-20% of all variceal bleeding. For the prevention of gastric variceal bleeding, TIPS or BRTO as firstline treatments were suggested.

No randomized trials have compared BRTO with other therapies. BRTO and its variations might increase portal pressure and might worsen complications, such as ascites or bleeding from EV. In this regard, if NSBB is combined with BRTO and its variations (we called interventional devascularization) for those HVPG responders, the drawbacks of interventional devascularization might be overcome. Therefore, the investigators conducted this RCT to compare the effectiveness and safety of TIPS with those of interventional devascularization in the prevention of rebleeding from gastric varices.

Read the detailed description

Gastric varices (GV) are present in around 20% of patients with cirrhosis. Bleeding from GV accounts for 10-20% of all variceal bleeding. GV are classified according to their location in the stomach and their relationship with esophageal varices (EV). Accordingly, GV are divided into gastroesophageal varices (GOV) and isolated gastric varices (IGV) . The management of type 1 GOV, which extend from the esophagus along the lesser curvature of the stomach, is similar to the management of EV. Historically, bleeding from type 2 GOV (i.e. GOV extending into the fundus), type 1 IGV (i.e. located in the fundus) and type 2 IGV (i.e. located anywhere in the stomach), is considered to be more severe and difficult to treat than EV bleeding. Few studies, mostly retrospective and uncontrolled, have focused on the management of non-GOV1 GV, and the optimal treatment remains controversial.

For the prevention of gastric variceal bleeding, treatment principles can be classified into two categories: decreasing portal pressure and obstructing GEV. Methods for decreasing portal pressure include medications (NSBB), radiological intervention (TIPS) and surgery. In contrast, methods for treating the obstruction of GEV include endoscopic approaches (EVL, EIS) or radiological intervention (such as BRTO). Recent portal hypertensive bleeding suggested TIPS or BRTO as firstline treatments in the prevention of rebleeding.

BRTO is a procedure for treatment of fundal varices associated with a large gastro-/splenorenal collateral. The technique involves retrograde cannulation of the left renal vein by the jugular or femoral vein, followed by balloon occlusion and slow infusion of sclerosant to obliterate the gastro-/splenorenal collateral and fundal varices. Several variations of the technique exist, such as balloon-occluded antegrade transvenous obliteration or occlusion of the collateral by the placement of a vascular plug or coils. BRTO has the theoretical advantage over TIPS that it does not divert portal blood inflow from the liver. On the other hand, BRTO and its variations might increase portal pressure and might worsen complications, such as ascites or bleeding from EV. In this regard, if NSBB is combined with BRTO and its variations (we called interventional devascularization) for those HVPG responders, the drawbacks of interventional devascularization might be overcome.

Therefore, the investigators conducted this RCT to compare the effectiveness and safety of TIPS with those of interventional devascularization in the prevention of rebleeding from gastric varices.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • interventional devascularizationProcedure or surgery

    Interventional devascularization (BRTO and its variations) is a procedure for treatment of fundal varices associated with a large gastro-/splenorenal collateral.

  • TIPSProcedure or surgery

    TIPS is very effective in the treatment of bleeding GV, with more than a 90% success rate for initial hemostasis. It frequently requires additional embolization of spontaneous collaterals feeding the varices. The incidence of encephalopathy was higher after TIPS.

Questions about this trial

What is this clinical trial studying?

A study testing interventional devascularization and TIPS in people with Gastric Varices Bleeding and Liver Cirrhoses, run by Air Force Military Medical University, China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jun Tie, M.D.,Ph.D. (+862984771537, tiejun7776@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative incidence of gastric variceal rebleeding (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Feb 2020.
