In general, this requires additional training beyond the core curriculum currently provided in each country. In this context, ESGE have developed a European core curriculum for optical diagnosis practice across Europe for high quality optical diagnosis training.<\/jats:p><jats:p>1\u2002ESGE suggests that every endoscopist should have achieved general competence in upper and\/or lower gastrointestinal (UGI\/LGI) endoscopy before commencing training in optical diagnosis of the UGI\/LGI tract, meaning personal experience of at least 300 UGI and\/or 300 LGI endoscopies and meeting the ESGE quality measures for UGI\/LGI endoscopy. ESGE suggests that every endoscopist should be able and competent to perform UGI\/LGI endoscopy with high definition white light combined with virtual and\/or dye-based chromoendoscopy before commencing training in optical diagnosis.<\/jats:p><jats:p>2\u2002ESGE suggests competency in optical diagnosis can be learned by attending a validated optical diagnosis training course based on a validated classification, and self-learning with a minimum number of lesions. If no validated training course is available, optical diagnosis can only be learned by attending a non-validated onsite training course and self-learning with a minimum number of lesions.<\/jats:p><jats:p>3\u2002ESGE suggests endoscopists are competent in optical diagnosis after meeting the pre-adoption and learning criteria, and meeting competence thresholds by assessing a minimum number of lesions prospectively during real-time endoscopy. ESGE suggests ongoing in vivo practice by endoscopists to maintain competence in optical diagnosis. If a competent endoscopist does not perform in vivo optical diagnosis on a regular basis, ESGE suggests repeating the learning and competence phases to maintain competence.<\/jats:p><jats:p>Key areas of interest were optical diagnosis training in Barrett\u2019s esophagus, esophageal squamous cell carcinoma, early gastric cancer, diminutive colorectal lesions, early colorectal cancer, and neoplasia in inflammatory bowel disease.
