The potential inclusion of the Sessile Serrated Polyp (SSP) detection rate as a KPI for quality colonoscopy is complicated by determining an accurate definition of a SSP. Reporting of an SSP can be pathologist dependent & may require detailed review of the endoscopic appearance alongside the histology report. Given that SSPs may be implicated in up to 30% of colorectal cancers and the burden associated with routine collection of such KPIs, the development and validation of a predictive calculation associated with polyp detection rates is attractive, and may circumvent inconsistent pathology reporting. However, consideration must be given to the different definitions of what is a clinically significant SSP & if the predictive calculation holds for the multiple definitions of SSP.
