The Influence of Post-transjugular Intrahepatic Portosystemic Shunt Hepatic Encephalopathy

August 8, 2019 updated by: Shanghai Zhongshan Hospital

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
