Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients undergo standard colonoscopy until the caecum is reached. Only a single colonoscopy will be performed on each patient (one-off).

Once the caecum is reached, all patients undergo sequential examination of colonic segments (as defined by the hepatic and splenic flexures) initially by NBI and then by chromoendoscopy.

The NBI and chromoendoscopy examinations are undertaken by two independent endoscopists.

NBI is activated by selecting a button on the standard colonoscope. It is then deactivated at the end of the examination of that segment.

There are no time limits imposed on the examination times however typically each examination takes 2-3minutes to examine.

Early detection / Screening
Intervention code [2] 264238 0
Prevention
Comparator / control treatment
Once a segment is examined by NBI then an independent endoscopist blinded to the results of the NBI examination examines the same segment using choromoendoscopy.

Chromoendoscopy involves applying 0.1% methylene blue solution to the bowel lining using a spray catheter and then examining that area.

There are no time limits imposed on the examination times however typically each examination takes 2-3minutes to examine.

Outcomes
Primary outcome [1] 5472 0
Diagnostic yield for dysplasia
Timepoint [1] 5472 0
At conclusion of the colonoscopy, the diagnostic yield for dysplasia will be measured for NBI and chromoendoscopy.
Secondary outcome [1] 273608 0
Accuracy of the Kudo classification by NBI in predicting neoplasia, calculated by comparing the prediction of neoplastic versus non neoplastic classification by NBY to actual histology.
Timepoint [1] 273608 0
At the conclusion of the study, the accuracy of the Kudo classification by NBI of any identified lesions will be calculated.
