Risk factors of missed colorectal lesions after colonoscopy.

Lee J, Park SW, Kim YS, et al. Medicine. 2017;96:e7468.

Failure to detect abnormalities during testing can lead to missed or delayed diagnoses. In this retrospective observational study, investigators found that nearly 20% of colonoscopies that needed to be repeated within 6 months had an undetected abnormal finding—a polyp—that was not initially detected. The authors caution that there is significant risk of missing abnormal findings on colonoscopy.
