120 diagnostic accuracy of high definition white light, narrow band imaging with or without near focus for assessment of colorectal endoscopic mucosal resection scars: escart trial (emr scar assessment trial), multicenter image evaluation study

High definition colonoscopy white light, narrow band imaging (NBI) with or without near-focus (an optical zoom providing sharp image within 2-6mm of intestinal mucosa) may aid in detection of subtle recurrence in the follow-up after EMR. If recurrence can confidently be excluded based on optical diagnosis, biopsy of EMR scar base can be avoided during surveillance colonoscopy. We aimed to test the diagnostic accuracy and inter-observer agreement of the optical diagnosis of EMR-scar recurrent neoplasia.
