No Correlation Between Detection and Optical Diagnosis in Colon Polyps
Douglas K. Rex, MD, FASGE, reviewing Bronzwaer MES, et al. Endoscopy 2020 Apr 29.
This is a Dutch multicenter study involving 24 colonoscopists who performed at least 50 colonoscopies in a fecal immunochemical test-positive population. All were high-performing colonoscopists previously trained in the optical diagnosis of colon polyps. In 2889 colonoscopies involving 9415 detected lesions, adenoma detection rates (ADRs), proximal serrated polyp detection rates (PSPDRs), and sensitivity for optical diagnosis of adenomas and serrated polyps were all highly variable. However, there was no significant correlation between ADR or adenomas per colonoscopy and sensitivity for optical diagnosis of adenomas. Further, there was no significant correlation between measures of serrated polyp detection and sensitivity for optical diagnosis of serrated lesions.

COMMENTThis is the second study to demonstrate a lack of correlation between detection and optical diagnosis skills. In fact, across several studies, we’ve now seen that cecal intubation, avoidance of complications, completeness of resection, and optical diagnosis are each and all independent of detection skill.
