We aimed to evaluate interobserver reliability and agreement for this classification among Western endoscopists.<\/jats:p><jats:p>\n          Methods\u2002A total of 54 superficial gastric lesions were independently classified according to Paris classification by eight endoscopists (4 experts and 4 non-experts). Observers were asked to classify two sets of images \u2013 first, obtained with high-resolution white light (HR-WL) endoscopy and secondly, with the same HR-WL images paired with images obtained with high-resolution Narrow Band Imaging (HR-NBI) \u2013 HR-WL\u200a+\u200aNBI image group.<\/jats:p><jats:p>\n          Results\u2002Overall interobserver reliability when asked to classify in I, II or III was good both using HR-WL images and HR-WL\u200a+\u200aNBI images (wK of 0.65 and 0.70, respectively). The proportion of agreement for type III lesions was 0.48 for HR-WL images increasing to 0.74 in the HR-WL\u200a+\u200aNBI group.\u200aInterobserver reliability for identification of a IIc component was only moderate (wK 0,47). NBI improves both sensitivity and interobserver reliability among trainees (from wK 0.19 to 0.47). Specificity was higher than sensitivity in predicting submucosal invasion.<\/jats:p><jats:p>\n          Conclusion\u2002Overall, the reliability of Paris classification is moderate to good. Training on this classification or its revision and use of technology such as NBI may improve not only reliability and agreement but also accuracy.<\/jats:p>","DOI":"10.1055\/a-0828-7541","type":"journal-article","created":{"date-parts":[[2019,5,2]],"date-time":"2019-05-02T18:43:18Z","timestamp":1556822598000},"page":"E633-E640","source":"Crossref","is-referenced-by-count":16,"title":["Reliability of Paris Classification for superficial neoplastic gastric lesions improves with training and narrow band imaging"],"prefix":"10.1055","volume":"07","author":[{"given":"Helena","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Amato Lusitano Hospital, Castelo Branco, Portugal"}]},{"given":"Diogo","family":"Lib\u00e2nio","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Portuguese Oncology Institute of Porto, Porto, Portugal"}]},{"given":"Rui","family":"Castro","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Portuguese Oncology Institute of Porto, Porto, Portugal"}]},{"given":"Anibal","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Hospital of Braga, Braga, Portugal"}]},{"given":"Pedro","family":"Barreiro","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Centro Hospitalar de Lisboa Ocidental, Lisboa, Portugal"}]},{"given":"Pedro","family":"Boal Carvalho","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Senhora da Oliveira Hospital, Guimar\u00e3es, Portugal"}]},{"given":"Tiago","family":"Capela","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Centro Hospitalar de Lisboa Ocidental, Lisboa, Portugal"}]},{"given":"Pedro","family":"Pimentel-Nunes","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Portuguese Oncology Institute of Porto, Porto, Portugal"},{"name":"Department of Surgery and Physiology, Porto Faculty of Medicine, Porto, Portugal"},{"name":"MEDCIDS\/Porto Faculty of Medicine, Porto, Portugal"}]},{"given":"Cristina","family":"Santos","sequence":"additional","affiliation":[{"name":"MEDCIDS\/Porto Faculty of Medicine, Porto, Portugal"}]},{"given":"M\u00e1rio","family":"Dinis-Ribeiro","sequence":"additional","affiliation":[{"name":"Gastroenterology Department, Portuguese Oncology Institute of Porto, Porto, Portugal"},{"name":"MEDCIDS\/Porto Faculty of Medicine, Porto, Portugal"}]}],"member":"194","published-online":{"date-parts":[[2019,5,2]]},"container-title":["Endoscopy International Open"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0828-7541.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T17:28:25Z","timestamp":1557163705000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0828-7541"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,5]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2019,5,3]]},"published-print":{"date-parts":[[2019,5]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0828-7541","relation":{},"ISSN":["2364-3722","2196-9736"],"issn-type":[{"value":"2364-3722","type":"print"},{"value":"2196-9736","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,5]]}}}
