Brief Summary:
The goal of this study is to compare the adenoma detection rate achieved while using either a 24" video monitor or a 32" video monitor.

Condition or disease Intervention/treatment Phase
Colon Adenoma Device: Monitor size Not Applicable

Detailed Description:
Gastrointestinal endoscopists perfoming routine endoscopic procedures and their patients will be randomized to one of two endoscopy rooms at the MGH Ambulatory Endoscopy Center at Charles River Plaza. The two rooms will have identical equipment with the exception that one room will have the current standard size video monitor (NDS 26") used at this facility while the other room will have a larger video monitor (NDS 32"). The ADR achieved by each physician in each room will be compared.

Arm Intervention/treatment
No Intervention: Standard monitor (24")
Endoscopists in this arm will perform colonoscopy using the standard size video monitor (24").
Active Comparator: Large monitor (32")
Subjects randomized to this group will perform colonoscopy while viewing a large video monitor (32").
 Device: Monitor size
Subjects will be randomized to perform their colonoscopy procedures while viewing a large (32") video monitor or the standard (24") video monitor.
