| description | Purpose
Combined use of contact endoscopy (CE) and Narrow Band Imaging (NBI, Olympus
®
) is suggested for the visualization of specific vascular changes indicative of glottic neoplasia. We investigated the interrater reliability and agreement in 3 recognized classification systems of vascular changes applied to images from CE + NBI in patients suspected for glottic neoplasia.
Methods
Six experienced head and neck surgeons familiar with NBI rated 120 images obtained by CE + NBI by 3 classification systems of vascular changes as suggested by Ni et al. (N-C), Puxeddu et al. (P-C), and the European Laryngological Society (ELS-C). Three raters were experienced in CE, and three raters had only limited experience with CE. Crude agreement and Fleiss’ kappa with 95% confidence interval were estimated for all 6 raters, and for the 2 levels of expertise for each original classification system and for dichotomized versions of the N-C and the P-C based on suggested neoplastic potential.
Results
The interrater crude agreement and the corresponding kappa values for the ELS-C were good and significantly higher than those for the N-C and P-C for all raters, irrespective of the level of experience with CE (

Results
The interrater crude agreement and the corresponding kappa values for the ELS-C were good and significantly higher than those for the N-C and P-C for all raters, irrespective of the level of experience with CE (
p
< 0.0001). There were no significant differences between the N-C and the P-C (
p
= 0.16). Kappa was considerably improved for both the N-C and the P-C to a level not different from the ELS-C (
p
= 0.21–0.71) when their 5 original categories were pooled into dichotomized classifications.
Conclusion
Difficulties in reliably classifying vascular changes in CE + NBI are evident. Two-tier classification systems are the most reliable.</description><identifier>ISSN: 0937-4477</identifier><identifier>EISSN: 1434-4726</identifier><identifier>DOI: 10.1007/s00405-020-06000-z</identifier><identifier>PMID: 32350646</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Endoscopy ; Head and Neck Surgery ; Humans ; Laryngology ; Larynx - diagnostic imaging ; Medicine ; Medicine & Public Health ; Narrow Band Imaging ; Neurosurgery ; Observer Variation ; Otolaryngology ; Otorhinolaryngology ; Reproducibility of Results</subject><ispartof>European archives of oto-rhino-laryngology, 2020-09, Vol.277 (9), p.2485-2492</ispartof><rights>Springer-Verlag GmbH Germany, part of Springer Nature 2020</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c391t-9a72241495ee8004905a875425ac800a2d5fa2342010bf9610013b825bde84443</citedby><cites>FETCH-LOGICAL-c391t-9a72241495ee8004905a875425ac800a2d5fa2342010bf9610013b825bde84443</cites><orcidid>0000-0002-5740-612X</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00405-020-06000-z$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00405-020-06000-z$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,780,784,27924,27925,41488,42557,51319</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/32350646$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Mehlum, Camilla Slot</creatorcontrib><creatorcontrib>Døssing, Helle</creatorcontrib><creatorcontrib>Davaris, Nikolaos</creatorcontrib><creatorcontrib>Giers, Anja</creatorcontrib><creatorcontrib>Grøntved, Ågot Møller</creatorcontrib><creatorcontrib>Kjaergaard, Thomas</creatorcontrib><creatorcontrib>Möller, Sören</creatorcontrib><creatorcontrib>Godballe, Christian</creatorcontrib><creatorcontrib>Arens, Christoph</creatorcontrib><title>Interrater variation of vascular classifications used in enhanced laryngeal contact endoscopy</title><title>European archives of oto-rhino-laryngology</title><addtitle>Eur Arch Otorhinolaryngol</addtitle><addtitle>Eur Arch Otorhinolaryngol</addtitle><description>Purpose
