Background/Aims Cold snare polypectomy (CSP) is the standard strategy for polyps <10 mm. Complete resection rates vary widely among endoscopists. The aim of this study was to evaluate a self-designed online course as an educational intervention to improve complete resection rates in colorectal polyps <10mm. Methods Multicenter trial including 12 Spanish endoscopists from 7 centers with two separated phases between 2021-2024. During the first phase, polyps <10mm were resected with CSP. After all endoscopists reached the estimated sample size, an hour-long online course conducted by an expert senior endoscopist was undertaken by all participants, commencing then the second phase. The complete resection rate was estimated with two marginal biopsies retrieved after CSP, which were submitted to a single pathologist blind to polyp histology. Follow-up was performed telephonically four weeks after the colonoscopy. Results A total of 1271 polyps in 598 patients were included in phase I and 827 polyps in 357 patients in phase II. An overview of polyps’ characteristics is summarized in table 1. Incomplete polypectomy mean rate was 4.85% in phase 1 and 3.92% in phase 2 (difference 0.93%, 95%CI: -0.96% to 2.83%). Individual data for each endoscopist are represented in Figure 1. Intraprocedural bleeding which not required endoscopic treatment was occurred in 118 and 50 cases, and needing endoscopic hemostasia in 11 and 12 patients respectively in each phase.953 (99.8%)patients were reached by phone for follow-up. Among 598 patients in phase 1 there were registered 4 delayed bleeding (3 mild, 1 severe), 7 abdominal pain and 11 mild adverse events and over 355 in phase 2 were detected 1 mild delayed bleeding. 1 abdominal pain and 2 minor adverse events. Conclusion The usefulness of online endoscopic technique courses seems limited. The excessive duration of the phases, due to the heterogeneity of endoscopists, could constitute a bias.
