Aims Our primary objective was to assess correlation between the adenoma detection rate (ADR) and sessile serrated lesion detection rate (SSL-DR). To evaluate whether endoscopist with high ADR are better at detecting SSLs.
Methods Retrospective study analysing electronic endoscopy database from an academic teaching hospital from January 1st to December 31st, 2018. Average-risk screening colonoscopies were analysed. Endoscopists were stratified by high and low ADRs (>/ = 25%, < 25%). SSL-DR defined as any serrated lesion of any size proximal to sigmoid colon divided by number of surveillance colonoscopies. Exclusion criteria: FAP/HNCC, IBD, diagnostic colonoscopy, patient < 50 years of age, incomplete colonoscopy or failure due to poor prep. Endoscopists who performed < 20 colonoscopies were excluded from the final analysis
Results 5,178 colonoscopies were performed, 4,348 of which were excluded from the analysis. 830 procedures by 22 endoscopists were analysed, comprising of 7 consultants and 15 trainees. The overall ADR, SSL-DR was 37% and 17% respectively. There was a statistically significant correlation between ADR and SSL-DR (r = 0.711, n = 22, p < 0.05). Endoscopists with an ADR > 25% had a significantly higher SSL-DR (19% vs 10%).
Conclusions Detection of SSLs at colonoscopy is important. Endoscopists with higher ADRs have higher SSL-DR. SSL-DR may have a use as a marker of endoscopist’s performance.
