In the West, the operative link for gastritis assessment (OLGA) and operative link for gastric intestinal metaplasia assessment (OLGIM) staging systems based on biopsy have been widely adopted. In Japan, however, narrow\u2010band imaging (NBI)\u2010magnifying endoscopic diagnosis of gastric mucosal inflammation, atrophy, and intestinal metaplasia has been reported to be fairly accurate. Therefore, we investigated the practicality of NBI\u2010magnifying endoscopy (NBI\u2010ME) for gastritis staging.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We enrolled 55 patients, in whom NBI\u2010ME was used to score the lesser curvature of the antrum (antrum) and the lesser curvature of the lower body (corpus). The NBI\u2010ME score classification was established from images obtained beforehand, and then biopsy specimens taken from the observed areas were scored according to histological findings. The NBI\u2010ME and histology scores were then compared. Furthermore, we assessed the NBI\u2010ME and histology stages using a combination of scores for the antrum and corpus, and divided the stages into two risk groups: low and high. The degree to which the stage assessed by NBI\u2010ME approximated that assessed by histology was then ascertained.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Degree of correspondence between the NBI\u2010ME and histology scores was 69.1% for the antrum and 72.7% for the corpus, and that between the high\u2010 and low\u2010risk groups was 89.1%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Staging of gastritis using NBI\u2010ME approximates that based on histology, and would be a practical alternative to the latter.<\/jats:p><\/jats:sec>","DOI":"10.1111\/den.12483","type":"journal-article","created":{"date-parts":[[2015,4,28]],"date-time":"2015-04-28T17:43:24Z","timestamp":1430243004000},"page":"735-742","source":"Crossref","is-referenced-by-count":42,"title":["OLGA\u2010 and OLGIM\u2010based staging of gastritis using narrow\u2010band imaging magnifying endoscopy"],"prefix":"10.1111","volume":"27","author":[{"given":"Akiko","family":"Saka","sequence":"first","affiliation":[{"name":"Department of Gastroenterology Niigata Prefectural Yoshida Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuyoshi","family":"Yagi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Niigata Prefectural Yoshida Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Nimura","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine Fukuoka University  Fukuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,6,8]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"6735","article-title":"Human gastric carcinogenesis: a multistep and multifactorial process \u2010 First American Cancer Society Award Lecture on Cancer Epidemiology and Prevention","volume":"52","author":"Correa P","year":"1992","journal-title":"Cancer Res."},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa001999"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humpath.2004.12.008"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dld.2008.02.030"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2009.12.029"},{"key":"e_1_2_9_7_1","first-page":"1446","article-title":"Magnifying endoscopic findings, using NBI, of chronic gastritis due to Helicobacter pylori infection","volume":"44","author":"Yagi K","year":"2009","journal-title":"Stom.
