About this study

Official title: Endoscopic Submucosal Dissection Using a Thulium Laser: Preliminary Results of a New Method for Treatment of Gastric Epithelial Neoplasia

We aim to evaluate safety and feasibility of a thulium laser system in performing endoscopic submucosal dissection of gastric neoplasia.

Read the detailed description

Instead of endoscopic knives, a thin, flexible fiber is inserted through the working channel of the endoscope. Acetic acid (1.5%) and indigo carmine dye are sprayed onto the lesion to clarify the margin. Markings are made 10 mm outside the tumor margin using a laser fiber with a power setting at 30 W. After marking, a mixture of sodium hyaluronate with indigo carmine and epinephrine (1:25000) is injected into the submucosa outside the marking dots. A circumferential mucosal incision and submucosal dissection are performed by a thulium laser fiber with a power setting at 30 to 40 W. Activation of the laser beam is controlled by stepping on a foot pedal. Hemostasis during procedure is also attempted using the thulium laser. When hemostasis is not achieved properly, additional use of hemostatic forceps or a hemoclip will be considered.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Technical success

    Curative resection rate

    Measured: 1 day

Secondary outcomes (1)
  1. Complication rate

    Procedure-related bleeding, perforation

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

An observational study of Gastric Dysplasia, run by Soonchunhyang University Hospital 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 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: finished, as of the sponsor's last update on 17 Nov 2015. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Technical success (time frame: 1 day). 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 NCT01753544, 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 17 Nov 2015.
