05). ORL-HNS imaging review classified 23 lesions (2.3 %, 95 % CI 1.5-3.4) as concerning and ORL-HNS clinic assessment was arranged. 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. check details 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 the first papilla type ( P  = 0.013). Conclusions  Our findings suggest that motion training could be an innovative method aimed at accelerating the learning curve of novice trainees in the early phase of their training. Future studies are needed to establish its role in ERCP training programs.Background and study aims  There are no reliable data to predict which patients with gastroparesis (GP) would benefit the most from gastric peroral endoscopic pyloromyotomy (G-POEM). The aim of the present study was to assess whether antro-duodenal motility patterns and pyloric distensibility can predict the outcome of G-POEM in patients with decompensated GP. Patients and methods  In an open-label study, patients with GP and refractory symptoms were eligible for treatment with G-POEM if treatment attempts according to a standardized stepwise protocol had failed. Baseline assessment included Gastroparesis Cardinal Symptom Index (GCSI), C13-octanoic gastric emptying breath test and high-resolution antro-duodenal manometry. Pyloric distensibility using EndoFlip measurements was assessed at baseline and 3 months after the procedure. Explorative analyses were performed on potential predictors of response using logistic regression analyses. Results  Twenty-four patients with decompensated GP underwent G-POEM. At baseline, 78.3 % and 61.9 % of patients showed antral hypomotility and neuropathic motor patterns, respectively. The technical success rate was 100 % (24/24). Mean GCSI improved significantly at 3, 6, and 12 months after G-POEM ( P  = 0.01). Median distensibility index (DI) improved significantly as compared with baseline (7.5 [6.9;11.7] vs. 5.3[3.1;8.1], P  = 0.004). A significant correlation was found between clinical response at 6 months and pyloric DI improvement ( P  = 0.003). No potential predictors of clinical response after G-POEM could be identified in an explorative analysis. Conclusions  G-POEM improved pyloric distensibility patterns in patients with decompensated GP. Clinical response at 6 months after G-POEM was associated with pyloric distensibility improvement. However, no potential predictors of response could be identified from either antro-duodenal motility patterns or pyloric distensibility.Background and study aims Endoscopy plays an essential role in managing patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. As such assessments are not always objective, different scores have been devised to standardize the findings. The main aim of this study was to assess the interobserver variability between the Mayo Endoscopy Score (MES), Ulcerative Colitis Endoscopy Index of Severity (UCEIS) and Ulcerative Colitis Colonoscopy Index of Severity (UCCIS) analyzing the severity of the endoscopic lesions in patients with ulcerative colitis. Patients and methods This was a single-cohort observational study in which a colonoscopy was carried out on patients with UC, as normal clinical practice, and a video was recorded. The results from the video were classified according to the MES, UCEIS and UCCIS by three endoscopic specialists independently, and they were compared to each other. The Mayo Endoscopy Score (MES) was used to assess the clinical situation of the patient. The therapeutic impact was analyzed after colonoscopy was carried out. Results Sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average MES was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the MES was 0.8; between A and C 0.52; and between B and C 0.49. The intraclass correlation coefficient for UCEIS was 0.92 among the three endoscopists (CI 95 % 0.83-0.96) and 0.96 for UCCIS among the three endoscopists (CI 95 % 0.94-0.97). A change in treatment for 34.3 % of the patients was implemented on seeing the results of the colonoscopy. Conclusions There was an adequate, but not perfect, correlation between the different endoscopists for MES, UCEIS, UCCIS. This was higher with the last two scores. Thus, there is still some subjectivity to be minimized through special training, on assessing the seriousness of the endoscopic lesions in patients with UC.
