The investigators hypothesize that NBI will have a high accuracy in predicting polyp histology real time during a colonoscopy by visualization of the surface mucosal and vascular patterns. Aim#1: To determine the sensitivity, specificity and accuracy of NBI and standard white light colonoscopy for predicting polyp histology by evaluating the surface mucosal and vascular patterns during colonoscopy. Aim#2: To determine the inter-observer agreement between investigators for the recognition of various polyp patterns.


Inclusion Criteria: - referral for screening or surveillance colonoscopy - the ability to provide informed consent Exclusion Criteria: - prior surgical resection of any portion of colon - prior history of colon cancer - history of inflammatory bowel disease - use of anti-platelet agents or anticoagulants that precludes removal of polyps during the procedure - poor general condition or any other reason to avoid prolonged procedure time - history of polyposis syndrome or Hereditary Non-polyposis colon cancer - inability to give informed consent
