Colorectal Neoplasms

Brief summary

Narrow band imaging or electronic chromoendoscopy might provide similar adenoma detection capabilities while limiting time spent when compared to conventional chromoendoscopy method.

Interventions

Blue light is used during withdrawal phase instead of the regular white light to highlight surface changes

Indigo carmine will be sprayed during withdrawal phase of colonoscopy

High definition equipment will be used to perform colonoscopy

Study design

Allocation
RANDOMIZED
Intervention model
PARALLEL
Primary purpose
SCREENING
Masking
SINGLE (Subject)

Masking description

Randomization cards will be sealed and opened after the subject is deemed eligible for the study by the PI. This will be done in an area away from the subject but due to the nature of the study, PI can't be blinded.

Eligibility

Age
40 Years to No maximum
