Plain English Summary

Background and study aims
A colonoscopy is a procedure used to examine the large bowel, the colon or the rectum. Colorectal cancer can be diagnosed using this type of procedure. The procedure involves the use of a device called a colonoscope. This study compares two devices and the aim is to assess which device will detect the highest number of precancerous lesions.

Who can participate?
Adult healthy volunteers over 50 referred for colonoscopy.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 undergo a colonoscopy using a standard colonosope. Those in group 2 undergo a colonoscopy using a G-EYE HD colonoscope.

What are the possible benefits and risks of participating?
Based on previous studies, use of the G-EYE colonoscope leads to improved detection of adenomas and serrated lesions. The G-EYE colonoscope is CE marked and used like any other colonoscope. Any complications that may result from the procedure are the same as those associated with a standard colonoscopy.

Where is the study run from?
A number of hospitals in Europe, Israel, India and the USA

When is the study starting and how long is it expected to run for?
May 2014 to January 2017

Who is funding the study?
Smart Medical Systems Ltd (Israel)

Who is the main contact?
Ms Avda Yoelzon
