About this study

Official title: Preoperative Mixed Reality Technique Combined With Three-Dimensional Printing Navigational Template Guided Localizing Pulmonary Small Nodules : a Prospective, Unicenter, Randomized Study.

This study evaluates the viability and accuracy of preoperative mixed reality technique combined with three-dimensional printing navigational template guided localizing pulmonary small nodules.

Read the detailed description

Pulmonary wedge resection is one of the most common types of operations performed by thoracic surgeons, especially given that more and more patients with ground glass nodules are being detected recently. One of the most significant current discussion concerning wedge resection is nodule localization. At present, a commonly used localization method is the CT-guided percutaneous lung puncture methylene blue staining marker localization, but this method has two main disadvantages: 1. the methylene blue dye is easy to spread, affecting the intraoperative judgment of nodule position by surgeon; 2. patients often suffer additional CT radiation. Mixed reality (MR) technique aims to enhance the simple self-visual effect and facilitate visualization of the surrounding environment in any situation. The three-dimensional model can be visualized by MR technique through MR glasses. Investigators project a three-dimensional reconstructed image of the patient's chest through MR glasses, then overlay the virtual chest with the actual chest, and then use this as a guide for percutaneous lung puncture localization. At the same time, investigators design an three-dimensional printing navigational template based on the 3D reconstruction model and place it on the surface of the body to help to guide the localization. This study is designed to evaluates the viability and accuracy of preoperative mixed reality technique combined with 3D printing navigational template guided localizing pulmonary nodules.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mixed Reality+ 3D printing guided localizationDevice

    Researchers project a three-dimensional reconstructed image of the patient's chest through MR glasses, then overlay the virtual chest with the actual chest. Finally, researchers put the three-dimensional printing navigational template on the surface of the body to guide for percutaneous lung puncture localization.

  • Computerized Tomography guided localizationDevice

    CT-guided percutaneous lung puncture staining marker localization.

What is being measured

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

  1. Puncture success rate of localization

    The deviations of less than 2 cm between the lesion and the injected site was defined as successful localization.

    Measured: During surgery

Secondary outcomes (1)
  1. Time of localization

    To evaluate the time of the localization in each groups. The investigators record the start and end time of localization respectively.

    Measured: During surgery

Questions about this trial

What is this clinical trial studying?

A study testing Mixed Reality+ 3D printing guided localization and Computerized Tomography guided localization in people with Video-assisted Thoracic Surgery and Lung Cancer, run by Wen-zhao ZHONG at 1 site in China.

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 3 inclusion and 5 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 17 Sep 2020. 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 China. 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 Wen-Zhao Zhong, Ph.D (+86-13609777314, 13609777314@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Puncture success rate of localization (time frame: During surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Sep 2020.
