Outcome Measures
Primary Outcomes (1)
Adenomas per colonoscopy
total number of adenomas divided by total number of procedures
during the procedure
Secondary Outcomes (5)
Adenoma detection rate
during the procedure
Sessile serrated polyps per colonoscopy
during the procedure
Sessile serrated polyp detection rate
during the procedure
Withdrawal time
during the procedure
Inspection time
during the procedure
Study Arms (3)
High definition white light endoscopy
PLACEBO COMPARATORcolonoscopy performed using high definition equipment
Chromoendoscopy
ACTIVE COMPARATORindigo carmine is sprayed on the colon mucosa during withdrawal phase
Narrow band imaging
EXPERIMENTALNarrow band imaging is used during withdrawal phase
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
