Study summary

The goal of this observation study is to learn about the feasibility of a new colonoscope which provides the physician an extra-wide field of view during a screening colonoscopy. The main question this study aims to answer is can this new type of colonoscope locate polyps during clinical use in patients.

Patients will undergo a routine colonoscopy for colorectal cancer or polyp surveillance and have one follow-up phone call up to 2 weeks of the colonoscopy.
