About this study
Though histoacryl injection is now regarded as treatment of choice in the control of gastric variceal hemorrhage, it may be associated with a lot of complications such as ulcers, ulcer bleeding, bacterial infections, distant site thrombosis and cerebral vascular accident. On the other hand, thrombin has been shown to be effective in acute hemostasis of bleeding gastric varices, ranging from 70% to 100% has been recorded. The rebleeding rates were between 7% and 50%. Moreover, the benefits of thrombin injection include safety, without inducing ulcers or ulcer bleeding. No incidence of distant thrombosis has ever been reported.
Read the detailed description
Previous studies have proven that the use of cyanoacrylate glue injection was superior to EIS or EVL in arresting acute gastric variceal bleeding. Endoscopic obturation with glue injection has gained worldwide popularity except the United States. The hemostatic rates of glue injection ranged from 87% to 100%, with rebleeding rates about 7% to 71%.

Moreover, the benefits of thrombin injection include safety, without inducing ulcers or ulcer bleeding. No incidence of distant thrombosis has ever been reported. The mechanism of hemostasis induced by thrombin is through the conversion of fibrinogen to fibrin and enhancement of platelets aggregation. This trial aimed to compare the relative efficacy and safety between histoacryl injection and thrombin injection in the prevention of gastric variceal rebleeding.

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 1 inclusion and 1 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 6 Nov 2012. 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 Taiwan. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ulcer on gastric varices (time frame: 1 month after therapy). 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 NCT01717612, which also lists 1 linked publication.
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 6 Nov 2012.
