Clinical Study on Endoscopic Management of GOV1 Esophagogastric Varices

August 22, 2023 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University

Clinical Study on Endoscopic Management of GOV1 Esophagogastric Varices Based on CT Hemodynamics

The patients with GOV1 esophagogastric varices will be treated with gastric variceal tissue gel injection, at the same time, the esophageal varices were treated with ligation, sclerotherapy, or no treatment. A new method for the treatment of esophageal varices will be proposed to improve the effective rate and reduce the recurrence rates and mortality, shorter hospital stays, and lower treatment costs, while further expanding HVPG testing to develop the best strategy for secondary prevention of endoscopic treatment in patients with GOV1 type esophageal and gastric varices.

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

Cirrhotic portal hypertension can cause esophageal and gastric varices, and esophageal and gastric varices bleeding (EGVB) were associated with portal vein pressure. At present, the gold standard for detecting portal pressure in clinical practice is hepatic venous pressure gradient (HVPG). For Sarin classification GOV1 of esophagogastric varices are from a single origin, the left gastric vein. If the fundus varicose veins receive complete embolization treatment, the esophageal variceal blood flow should be completely blocked, and such patients do not need to perform esophageal surgery. However, this has not been reported in the literature.

Patients with esophageal and gastric varices identified by CT as GOV1 will be enrolled, all of whom will receive HVPG detects. The patients were randomly divided into three groups. The patients in group A will receive endoscopic gel embolization for gastric varices and esophageal varices ligation treatment, group B patients will receive endoscopic gastric variceal tissue glue embolization and esophageal variceal sclerotherapy treatment, the patients in group C will receive endoscopic gelatinization of gastric fundus varices (esophageal varices were not treated). Patients in the three groups were followed up with CTP and gastroscopy 1 month, 3 months, and 6 months after the initial treatment, and additional endoscopic treatment will be provided if necessary. If bleeding occurs again during this period, timely treatment (medication, endoscopy, intervention or surgery) is required according to the condition.

A new method for the treatment of esophageal varices will be proposed to improve the effective rate and reduce the recurrence rates and mortality, shorter hospital stays, and lower treatment costs, while further expanding HVPG testing to develop the best strategy for secondary prevention of endoscopic treatment in patients with GOV1 type esophageal and gastric varices.

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.

Ages Eligible for Study
