Optical polyp diagnosis and the current resect and discard approach are too complex for clinical adoption. Thus, clinical implementation of this valuable concept has not been achieved to date and its cost-saving potential has not been realized. In order to effectively operationalize a resect and discard strategy, one must find a different way to distinguish neoplastic from non-neoplastic polyps. There exist differences in the proportion of polyps found to be adenomatous in the left and right colon. One recent study reported that 30% of left-sided polyps and 76% of right-sided polyps were found to be adenomas on histology. Since polyps located in the proximal colon are more likely to be adenomas and polyps in the recto-sigmoid colon are more likely hyperplastic we hypothesized that a model based on polyp location might be able to replace optical biopsy and histopathology. Such an approach would be very simple to adopt by every clinician and would allow for easy adoption into clinical practice.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '45 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'All 45-80 year old patients scheduled for an elective colonoscopy with the potential of a polyp removal will be considered for the study.
