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 COMPARATOR

colonoscopy performed using high definition equipment

Other: High definition white light endoscopy

Chromoendoscopy

ACTIVE COMPARATOR

indigo carmine is sprayed on the colon mucosa during withdrawal phase

Other: Chromoendoscopy

Narrow band imaging

EXPERIMENTAL

Narrow band imaging is used during withdrawal phase

Device: Narrow band imaging

Interventions

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

Narrow band imaging

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
