About this study

It exists a learning curve in using NBI with magnification to differentiating colorectal lesions.

Read the detailed description

It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.

What is being measured

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

  1. Accuracy, Sensitivity, and Specificity for Differentiating Neoplastic and Non-neoplastic Lesions

    Measured: For this training, patients were consecutively enrolled until a total of 45 target and non-target lesions were obtained.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Lesion, run by Zhizheng Ge.

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 2 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: finished, as of the sponsor's last update on 1 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 1 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Accuracy, Sensitivity, and Specificity for Differentiating Neoplastic and Non-neoplastic Lesions (time frame: For this training, patients were consecutively enrolled until a total of 45 target and non-target lesions were obtained.). 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 1 Mar 2017.
