Endoscopist experience in the regional screening cohort In the regional 332 LNPCP cases, 24 endoscopists were involved. Fifteen (63%) had more than 10 years of experience and 9 (38%) were dedicated to advanced polypectomy programs in their center. The direct surgery referral and technical success rates were, respectively, 51% and 71% for non-experienced, non-dedicated endoscopists, 17% and 88% for intermediate group endoscopists, and 8% and 90% for experienced, dedicated endoscopists ( P <0.001 and P =0.064, respectively). Direct surgery referral rates and technical success rates for experienced versus non-experienced and dedicated versus non-dedicated endoscopists are shown in Table 5.7 and 5.8 .
