NCT03908229

Brief Summary

Previous studies that examined whether the presence of an additional observer, more specifically a GI fellow, during colonoscopy can enhance detection of all polyps and adenomas yielded conflicting results. Of note, all of the aforementioned studies were retrospective and robust evidence derived from well-designed randomized controlled trials are lacking. The study objective is to examine whether fellow participation during screening, surveillance, or diagnostic colonoscopy influence overall, size-specific, or location-specific adenoma or polyp detection rate. It will be planned to enroll 812 patients (406 per arms) within 1 year. Adenoma detection rate will be the primary outcome.

Outcome Measures

Primary Outcomes (1)

  • Adenoma detection rate

    12 months

Secondary Outcomes (4)

  • Advanced adenoma detection rate

    12 months

Study Arms (2)

Trainee colonoscopy

EXPERIMENTAL

In the investigation arm colonoscopy will be performed by gastroenterology fellows. The fellows will always start the case and proceed generally until they are unable to make further progress despite "coaching" from the staff attending. During the procedures with fellows, the staff attending will always actively participate in the entire procedure and assess for the presence of any lesions.

Procedure: Trainee colonoscopy

Experienced physician colonoscopy

ACTIVE COMPARATOR

In the control arm all colonoscopy will be performed by full-time board-certified gastroenterologists who have each done more than 5000 colonoscopy examinations.

Procedure: Experienced physician colonoscopy

Interventions

Colonoscopy performed by trainee
