About this study
Official title: Efficacy and Safety Evaluation of Advanced Vessel Sealing Device (Vi-sealer)
This study's primary goal is to compare the efficacy and safety of the novel advanced hemostatic device(AHD), Vi-Sealer, with conventional AHDs in laparoscopic total hysterectomy for patients with benign gynecologic neoplasm.
Read the detailed description
Vi-Sealer is a reusable advanced bipolar electrode with an interchangeable blade. This study evaluates the efficacy and safety of the Vi-Sealer by comparing it with other advanced hemostatic devices, such as Ligasure, Enseal, Thunderbeat, Harmonic scalpel, etc. The economic evaluation of the device compared with other disposable devices would also be conducted.

Questions about this trial
What is this clinical trial studying?
A study testing Vi-Sealer, Ligasure and Other AHD in people with Benign Gynecologic Neoplasm, run by Hyun Park at 1 site in South Korea.
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 4 inclusion and 7 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 1 Oct 2024. 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 South Korea. 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 Hyun Park (+82-031-780-5640, p06162006@cha.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Operative procedure time (time frame: through study completion, an average of 1 year). The study lists 2 primary outcomes in all. 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 NCT05629611, which also lists 15 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?
