Sessile serrated lesions: Searching for the true prevalence
Reality is merely an illusion, albeit a very persistent one – Albert Einstein
The serrated class of colorectal polyps includes hyperplastic polyps (HP), sessile serrated lesions (SSL), and traditional serrated adenomas (TSA). Among these, SSL are the most screening-relevant, because they are considered the main precursor lesion in the serrated colorectal cancer (CRC) pathway, and are much more prevalent than TSAs [1]. The growing recognition of the importance of SSLs has been accompanied by numerous studies reporting detection rates at colonoscopy. Inevitably, systematic reviews and meta-analyses have followed, reporting aggregates of available SSL detection studies. It is important here to distinguish between aspirational detection rates, which are more reflective of the true population-based SSL prevalence, and the more commonly reported overall SSL detection rates among groups of endoscopists.
