EndoRings Colonoscopy vs Standard Colonoscopy

A Randomized Trial Comparing the Adenoma Detection Rates Between EndoRings Colonoscopy (EC) and Standard Colonoscopy (SC).

The study aims to compare the results between a standard colonoscopy to a colonoscopy with an attachment on the distal end of the colonoscope.

This will be a prospective, randomized controlled study. Subjects referred for screening or surveillance colonoscopy will be prospectively enrolled. This study aims to compare the adenoma detection rates between EndoRings colonoscopy (EC) and Standard colonoscopy (SC). It is assumed that the proportion of patients with at least one adenoma would be 25% with SC and 35% with EC.
