Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In order to evaluate how effective right colon retroflexion is at detecting polyps in the proximal colon we plan on performing a randomized, controlled trial. Patients undergoing screening or follow up colonoscopy will be invited to participate in the study. Those patients who agree to participate will be randomized into one of two groups once the colonoscope is fully inserted. Group one will have the right side of their colon examined for polyps with the endoscope looking forward (traditional form of examination) followed by repeat examination of the right side of the colon with the colonosocpe in retroflexion (looking backwards). Polyps seen during each section of the exam will be removed and manner in which the polyps were found/ removed will be recorded. Following the two exams of the right side of the colon the colonoscopy will be completed in the usual manner. The duration of each portion of colonoscopy will be recorded. After the procedure is completed the physician performing the colonoscopy will rate difficulty of the procedure and confidence with quality of the examination. Pathology results for each polyp will be recorded once available. There will be no study related follow up after the pathology results are recorded.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Retroflexion arm
Retroflexion arm: retroflexion in the cecum or proximal ascending colon and slow withdrawal to the hepatic flexure with removal of all visible colon polyps
Retroflexion in the right colon
Forward view arm
Colonoscope is slowly withdrawn from the proximal colon to the hepatic flexure and all visible colon polyps are removed.
