colonoscopy performed using high definition equipment

indigo carmine is sprayed on the colon mucosa during withdrawal phase

Narrow band imaging is used during withdrawal phase

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

Chromoendoscopy

High definition equipment will be used to perform colonoscopy

High definition white light endoscopy

Douglas Rex, MD

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

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.

Chromoendoscopy or Narrow Band Imaging (NBI) for Improving Adenoma Detection in Colonoscopy

total number of adenomas divided by total number of procedures

total number of patients with adenomas divided by total number of procedures

total number of sessile serrated polyps divided by total number of procedures

total number of patients with sessile serrated polyps divided by total number of procedures

Time from cecal intubation to end of the procedure

Time during withdrawal minus time for interventions including washing, suctioning and polypectomy or biopsies
