This identified six PECLs (0.6 %, 95 % CI 0.2-1.3) including two pharyngeal squamous cell lesions (0.2 %) demonstrating high-grade dysplasia and carcinoma in situ (CIS) and four premalignant glottic lesions (0.4 %) demonstrating low-grade dysplasia and CIS. Conclusion  In the routine setting of a gastrointestinal endoscopy practice precancerous and early cancerous lesions of the oropharynx, hypopharynx, and larynx are rare ( less then  1 %) but can be detected with a structured assessment of this region during routine upper gastrointestinal endoscopy.Background and study aims  Current data show that traditional training methods in endoscopic retrograde cholangiopancreatography (ERCP) fall short of producing competent trainees. We aimed to evaluate whether a novel approach to simulator-based training might improve the learning curve for novice endoscopists training in ERCP. Methods  We conducted a multicenter, randomized controlled trial using a validated mechanical simulator (the Boškoski-Costamagna trainer). Trainees with no experience in ERCP received either standard cannulation training or motion training before undergoing standard cannulation training on the mechanical simulator. Trainees were timed and graded on their performance in selective cannulation of four different papilla configurations. Results  Thirty-six trainees (16 in the motion training group, 20 in the standard group) performed 720 timed attempts at cannulating the bile duct on the simulator. Successful cannulation was achieved in 698 of 720 attempts (96.9 %), with no significant difference between the two study groups ( P  = 0.37). Trainees in the motion training group had significantly lower median cannulation times compared to the standard group (36 vs. 48 seconds, P  = 0.001) and better technical performance on t
