Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Removal of colorectal adenomas prevents the occurence of colorectal cancers. The use of chromo-endoscopy has been shown to improve the detection of flat adenomas. Narrow band imaging enables endoscopists to accurately describe the pit pattern of adenomas. By comparing White Light Endoscopy and Bright Narrow Band Imaging it will show if there is any comparable advantage to using one or the other for lesion detection and assessment.
