Trends in Adenoma Detection Rates During the First 10 Years of the German Screening Colonoscopy Program

We observed a strong increase in ADRs from 2003 through 2012 in Germany. Although we cannot exclude the effects of secular trends in colorectal neoplasm prevalence, the observed increase was mainly the result of a steady increase in detection of nonadvanced adenomas (especially adenomas <0.5 cm). Further research should address potential implications for defining screening and surveillance intervals.
