  • Neoplasm Miss Rate

    same day

Secondary Outcomes (3)

  • Neoplasm Detection Rates

    same day

  • Completion of Examinations

    same day

  • Procedure Complications

    procedure and post-procedure complications within 30 days after colonoscopy

Study Arms (2)

Narrow band imaging colonoscope

EXPERIMENTAL

narrow band imaging colonoscope

Device: Narrow band imaging colonoscope

White Light

NO INTERVENTION

Conventional White Light Examination

Interventions

Adult colonoscopes with narrow band imaging capabilities (XCF-H160AY2L and XCF-Q160W6L, Olympus Medical Systems Corporation, Hachioji, Japan). There is an automatic switch on the handle of the endoscope that allows the physician to instantly switch between narrow band imaging and standard full spectrum white light modes.
