Outcome Measures
Primary Outcomes (2)
Adenoma Detection Rate (All Indications)
Number of patients with adenoma detected
within 2 weeks (range of 1 day-14 days) of the endoscopy
Adenoma Detection Rate (Screening Exams Only)
Number of patients with adenoma detected
within 2 weeks (range of 1 day-14 days) of the endoscopy
Secondary Outcomes (2)
Polyp Detection Rate (All Indications)
recorded during endoscopy (immediate)
Polyp Detection Rate (Screening Exams Only)
recorded during endoscopy (immediate)
Study Arms (2)
Standard monitor (24")
NO INTERVENTIONEndoscopists in this arm will perform colonoscopy using the standard size video monitor (24").
Large monitor (32")
ACTIVE COMPARATORSubjects randomized to this group will perform colonoscopy while viewing a large video monitor (32").
Interventions
Subjects will be randomized to perform their colonoscopy procedures while viewing a large (32") video monitor or the standard (24") video monitor.
