Brief Summary
To compare the adenoma miss rate with the EndoRings™ vs. the adenoma miss rate with Standard view colonoscopy. To compare the polyp miss rate with the EndoRings™ vs. the polyp miss rate with Standard view colonoscopy.In addition, time measurements including time to cecum, time for withdrawal and overall procedure time will be analyzed and reported for each group.

Outcome Measures
Primary Outcomes (1)
Adenoma and Polyp Miss Rate
Group A- we measured the Adenoma\&Polyp miss rates in the first procedure with Standard (based on what we discovered on the second procedure with the EndoRings). Group B- we measured the Adenoma\&Polyp miss rates in the first procedure with EndoRings (based on what we discovered on the second procedure with the Standard). Adenoma/Polyp Miss Rate means: total number of adenomas or polyps detected during the second procedure per Group divided by the total number of adenomas/polyps detected overall per Group\]\*100
30min for Standard colonoscopy and 30min for EndoRings colonoscopy- 1 hour in total.
Secondary Outcomes (6)
Total Number of Therapeutic Interventions Performed

Study Arms (2)
Group A
OTHERTandem Colonoscopy- Each patient will undergo 2 colonoscopy procedures: a Standard view colonoscopy followed immediately by an EndoRings™ colonoscopy.
Group B
OTHERTandem Colonoscopy- Each patient will undergo 2 colonoscopy procedures: an EndoRings™ colonoscopy followed immediately by a Standard view colonoscopy.
Interventions
Each patient will undergo a double procedure: standard colonoscopy using the EndoRings™ add-on device and Standard colonoscopy (without using the EndoRings™ add-on device) in a randomized order.
Eligibility Criteria
You may qualify if:
- Subject between the ages of 40 and 75
- The patient is undergoing colonoscopy for screening, for surveillance in follow-up of previous polypectomy or for diagnostic workup;
- Written informed consent must be available before enrollment in the trial
You may not qualify if:
- Patients with a history of colonic resection;
- Patients with known (or newly diagnosed) inflammatory bowel disease;
- Patients with a personal history of polyposis syndrome;
- Patients with suspected chronic stricture potentially precluding complete colonoscopy;
- Patients with diverticulitis or toxic megacolon;
- Patients with a history of radiation therapy to abdomen or pelvis;
- Patients with a hemorrhagic diathesis
- Patients with acute lower GI bleeding
- Pregnant women and women with childbearing potential without adequate contraception
- Patients who are currently enrolled in another clinical investigation in which the intervention might compromise the safety of the patient's participation in this study.
