Full Inspection With Narrow Band Imaging (NBI) for Detection of Flat Lesions And Tumors During Colonoscopy- The FIND FLAT Colonoscopy Study
We hypothesize that high definition narrow band imaging (NBI) colonoscopy compared to high
definition white light colonoscopy will detect an increased number of nonpolypoid (flat and
depressed) colorectal neoplasm.
definition white light colonoscopy will detect an increased number of nonpolypoid (flat and
depressed) colorectal neoplasm.
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.
