Methods: We retrospectively identified 60 resected SNADETs (31 category 3 lesions and 29 category 4\/5 lesions) in 60 patients who underwent M-NBI and MA-NBI preoperatively. We evaluated vascular and surface patterns using M-NBI and MA-NBI for characterizing category 3 and 4\/5 lesions. The surface pattern was classified as tubular, villous, or mix structure using MA-NBI. In addition, lesions with disorganized and unclear structures with irregular margins that can be clearly recognized by MA-NBI were defined as irregular surface structures. Results: For MA-NBI, category 4\/5 lesions had a significantly higher mix structure rate and higher irregular surface structure rate than category 3 lesions (62 vs. 16%, p &lt; 0.001, and 86 vs. 19%, p &lt; 0.001, respectively). The diagnostic accuracy of MA-NBI using mix and irregular surface structures for identifying category 4\/5 lesions was as follows: sensitivity, 62\/86%; specificity, 84\/77%; positive predictive value, 78\/78%; negative predictive value, 70\/86%; and accuracy, 73\/82%. The diagnostic accuracy of MA-NBI using irregular surface structure was significantly higher than that of M-NBI (p &lt; 0.05). Conclusion: MA-NBI may be useful in differentiating between category 3 and category 4\/5 lesions of SNADETs. <\/jats:p>","DOI":"10.1159\/000509854","type":"journal-article","created":{"date-parts":[[2020,8,26]],"date-time":"2020-08-26T21:00:32Z","timestamp":1598475632000},"page":"572-579","source":"Crossref","is-referenced-by-count":9,"title":["Efficacy of Magnifying Narrow Band Imaging with Acetic Acid Spray in Diagnosing Superficial Non-Ampullary Duodenal Epithelial Tumors"],"prefix":"10.1159","volume":"102","author":[{"given":"Yasuyuki","family":"Tanaka","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigehiko","family":"Fujii","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoko","family":"Oiwa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiro","family":"Kusaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinsuke","family":"Shibuya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Kokuryu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2020,8,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111\/den.12277"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1443-1661.2010.01014.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/den.12104"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i35.12501"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1390774"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159\/000452363"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2010.422"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111\/den.12259"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2016.12.007"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/den.12282"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v21.i41.11832"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-103681"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1080\/00365521.2018.1557740"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2013.11.033"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2001.114059"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i43.16306"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1136\/gut.51.1.130"}],"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/dig\/article-pdf\/102\/4\/572\/4028840\/000509854.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/dig\/article-pdf\/102\/4\/572\/4028840\/000509854.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:50:53Z","timestamp":1745423453000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000509854"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,26]]},"references-count":17,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2021,6,29]]},"published-print":{"date-parts":[[2021,7,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000509854","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,26]]}}}
