Primary Outcome Measures:
  • G-EYE™ colonoscopy detection rate of adenomas and serrated lesions compared to the standard colonoscopy detection rate of the same. [ Time Frame: Approximalty following 14 days (histology results) ]

Secondary Outcome Measures:
  • Number of polyp and adenoma detection, procedure times and safety (number of patients with adverse events. [ Time Frame: Up to 14 days (histology results) ]
    The secondary outcome is a composite-each of the measured parameters will be reported as a single value for each arm

Enrollment: 1000
Study Start Date: May 2014
Primary Completion Date: October 2016 (Final data collection date for primary outcome measure)

Detailed Description:

This is a multicenter, two-arm, randomized, open-label study intended to compare the detection rate obtained by performing G-EYE™ high definition colonoscopy vs. the detection rate obtained by performing high definition standard colonoscopy.

The study will enroll 1000 subjects. Consecutive adult subjects who were referred for elective colonoscopy will be asked to enroll into this randomized clinical study if the candidate meets the study inclusion and exclusion criteria.

Subjects will sign informed consent form and undergo randomization. The study includes a run-in preliminary phase of 270 patients to allow physicians to get familiar with the G-EYE™ endoscope.
