Outcome Measures

Primary Outcomes (1)

  • Adenoma detection rate

    The proportion of subjects with at least one adenoma

    7 days is needed to confirm the pathologic examination.

Secondary Outcomes (6)

  • Proximal adenoma detection rate

    7 days is needed to confirm the pathologic examination.

  • Proximal serrated polyp detection rate

    7 days is needed to confirm the pathologic examination.

  • Advanced adenoma detection rate

    7 days is needed to confirm the pathologic examination.

  • Serrated adenoma detection rate

    7 days is needed to confirm the pathologic examination.

  • Cancer detection rate

    7 days is needed to confirm the pathologic examination.

  • +1 more secondary outcomes

Study Arms (2)

cap-assisted chromoendoscopy

EXPERIMENTAL

To the tip of the colonoscope, transparent cap is fitted and applied. In addition, panchromoendoscopy using indigocarmine solution is preformed in this group.

Device: cap-assisted chromoendoscopy

Standard colonoscopy

NO INTERVENTION

Neither transparent cap nor chromoendoscopy is applied in this group and standard colonoscopy is performed.

Interventions

A cap (irrigation cap) is a simple plastic device that can be attached to the tip of a colonoscope before performing the colonoscopy. For chromoendoscopy, 0.09% indigocarmine was administered via irrigation cap .
