Full Inspection With Narrow Band Imaging (NBI) for Detection of Flat Lesions And Tumors During Colonoscopy- The FIND FLAT Colonoscopy Study
Interval colorectal cancers diagnosed within a three year period following a clearing
colonoscopy have been reported at a rate of 1 cancer/1000 person years.The majority of these
cancers are likely a consequence of a missed neoplastic lesion during routine colonoscopy.
Recent tandem colonoscopy studies have shown no significant difference in adenoma miss or
detection rates using narrow band imaging as compared to colonoscopy using white light.
However, higher detection of flat neoplastic lesions using NBI was shown in a meta-analysis
and should be furthered studied, especially considering that they are thought to be a strong
contributor to a false negative colonoscopy.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Diagnostic
Nonpolypoid (flat and depressed) colorectal neoplasm detection.
Compare the nonpolypoid colorectal neoplasm detection characteristics of the new high definition narrow band imaging colonoscopy to conventional high definition white light mode colonoscopy.
