Iriscope\u00ae is a novel device that provides a direct and real-time image of PPLs. The objective of this study was to demonstrate the feasibility and impact of Iriscope\u00ae in diagnosing PPLs by analyzing its ability to directly visualize lesions and support accurate sampling during radial probe endobronchial ultrasound (rEBUS) and electromagnetic navigation bronchoscopy (ENB) combined with rEBUS. Methods: A single-center prospective study was conducted from December 2022 to October 2023 on patients with suspicious PPLs. The diagnostic approach involved either rEBUS alone or in combination with ENB. In all cases, an additional novel technique called Iriscope\u00ae (Lys Medical, Charleroi, Belgium) was also applied. Iriscope\u00ae findings of each lesion were evaluated individually by three expert interventional pulmonologists. Results: Seventy PPLs suspected of malignancy were included in the study. The PPLs underwent examination by ENB combined with rEBUS (55) or by rEBUS alone (15). Diagnosis was obtained in 68.6% (48\/70) of cases. Iriscope\u00ae provided a direct, real-time view of 57.1% (40\/70) of PPLs with a positive predictive value of 92.5% (37\/40). This technique was able to visualize 72% (39\/54) of malignant lesions, while only 6.1% (1\/16) of benign lesions showed pathologic changes. The most common findings observed with Iriscope\u00ae were mucosal thickening and infiltration (92.5%), increased capillary vascularization (82%), pale or grayish mucosa (72.5%), obstruction with accumulation of secretions (50%), and cobblestone mucosa (15%). Conclusion: Iriscope\u00ae is a promising technique in the diagnostic process of PPLs, providing real-time pathologic imaging that facilitates accurate sampling. Further studies are needed to evaluate success rate of Iriscope-mediated repositioning and to establish predictive patterns for malignant or even benign diseases. <\/jats:p>","DOI":"10.1159\/000541675","type":"journal-article","created":{"date-parts":[[2024,10,4]],"date-time":"2024-10-04T16:01:24Z","timestamp":1728057684000},"page":"1-9","source":"Crossref","is-referenced-by-count":4,"title":["Feasibility and Impact on Diagnosis of Peripheral Pulmonary Lesions under Real-Time Direct Vision by Iriscope<sup>\u00ae<\/sup>"],"prefix":"10.1159","author":[{"given":"Borja","family":"Recalde-Zamacona","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Alfayate","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Gim\u00e9nez-Velando","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Romero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iker","family":"Fern\u00e1ndez-Navamuel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Flandes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2024,10,4]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21763"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(23)00444-8"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1102873"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1911793"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.202401-0192ST"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/1759-7714.13930"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00165306"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1378\/chest.12-2353"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtho.2018.11.013"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200612-1866OC"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.lungcan.2023.107196"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159\/000512802"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097\/LBR.0000000000000783"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1097\/LBR.0000000000000815"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.34197\/ats-scholar.2021-0121OC"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.chest.2019.06.038"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.3390\/cancers13040820"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1111\/1759-7714.12423"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/res\/article-pdf\/doi\/10.1159\/000541675\/4293579\/000541675.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/res\/article-pdf\/doi\/10.1159\/000541675\/4293579\/000541675.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T14:52:25Z","timestamp":1745419945000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000541675"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,4]]},"references-count":18,"URL":"https:\/\/doi.org\/10.1159\/000541675","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"value":"0025-7931","type":"print"},{"value":"1423-0356","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,10,4]]}}}
