About this study

Official title: The Influence of Shunting Left/Right Portal Vein Branch on Post-transjugular Intrahepatic Portosystemic Shunt Hepatic Encephalopathy: a Multicenter Randomized Controlled Trial

Through a multicenter randomized controlled trial of TIPS to prevent post-hepatitis B cirrhosis of esophagogastric varices, the incidence of hepatic encephalopathy, the rate of stent patency, the incidence of rebleeding and survival in the left and right branches of the portal vein were compared.

Read the detailed description

The most common cause of cirrhosis in China is hepatitis B virus infection; post-hepatitis B cirrhosis with gastroesophageal variceal hemorrhage is common in clinical practice; recent studies [14] found that implantation of 8 mm diameter is compared with the use of 10 mm diameter stents. The membrane stent significantly reduced the incidence of HE after TIPS without affecting the shunt effect. To further evaluate the effect of "left/right branch of shunt portal" on hepatic encephalopathy after TIPS, we intend to conduct the following studies: for individual etiology (post-hepatitis B cirrhosis), the only indication (to prevent recurrent rupture of gastroesophageal varices) ), implanted 8mm diameter Viatorr stent, unified HE evaluation criteria, and stratified multi-center randomized clinical trial study with Child classification, hope to guide TIPS in line with China's national conditions through the high-level evidence-based medical evidence obtained.

Questions about this trial

What is this clinical trial studying?

A study testing trans jugular intrahepatic portal systemic shunt in people with Portal Hypertension and Hepatic Encephalopathy, run by Shanghai Zhongshan Hospital at 1 site in 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 9 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 9 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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 Jianjun Luo, Doctor (+86 13801924777, luo.jianjun@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of HE (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03825848, which also lists 4 linked publications.

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 9 Aug 2019.
