Rigid medical thoracoscopy offers distinct clinical value for a complete visual inspection, large biopsies, and potential pleurodesis, particularly in suspected mesothelioma cases. The currently available evidence does not support the routine replacement of semirigid medical thoracoscopy with cryobiopsy. Computed tomography-guided biopsy may be preferred in cases involving thickening \u226510\u2005mm or small target lesions. Conversely, ultrasound-guided biopsy may be appropriate for lesions measuring \u22653\u2005mm with a clear acoustic window. UE-guided pleural biopsy shows promise as an emerging option, although the evidence is limited. In tuberculous pleurisy, medical thoracoscopy may offer higher diagnostic sensitivity in certain settings, particularly in high-prevalence areas. The current evidence is insufficient to establish a clear advantage for any biopsy method regarding the overall complication risk.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1183\/16000617.0310-2025","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T08:30:29Z","timestamp":1781080229000},"page":"250310","update-policy":"https:\/\/doi.org\/10.1183\/ers-crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Diagnostic performance and safety of image-guided pleural biopsy and medical thoracoscopy for undiagnosed exudative pleural effusion: a systematic review and network meta-analysis"],"prefix":"10.1183","volume":"35","author":[{"given":"Shuping","family":"Lyu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1711-6328","authenticated-orcid":false,"given":"Ziwen","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liwei","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoguo","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingming","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2734-8061","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Porcel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3438-1764","authenticated-orcid":false,"given":"Gang","family":"Hou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"2026061001301405000_35.180.250310.1","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.01254-2018"},{"key":"2026061001301405000_35.180.250310.2","doi-asserted-by":"publisher","DOI":"10.1136\/thorax-2023-220304"},{"key":"2026061001301405000_35.180.250310.3","doi-asserted-by":"publisher","DOI":"10.1136\/thx.34.1.106"},{"key":"2026061001301405000_35.180.250310.4","doi-asserted-by":"crossref","first-page":"446","DOI":"10.21037\/tlcr.2020.03.28","article-title":"Comparison between closed pleural biopsy and medical thoracoscopy for the diagnosis of undiagnosed exudative pleural effusions: a systematic review and meta-analysis","volume":"9","author":"Wei","year":"2020","journal-title":"Transl Lung Cancer Res"},{"key":"2026061001301405000_35.180.250310.5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1843.2007.01144.x"},{"key":"2026061001301405000_35.180.250310.6","doi-asserted-by":"publisher","DOI":"10.1136\/thorax-2022-219371"},{"key":"2026061001301405000_35.180.250310.7","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1016\/S0140-6736(58)92521-2","article-title":"A pleural-biopsy punch","volume":"1","author":"Abrams","year":"1958","journal-title":"Lancet"},{"key":"2026061001301405000_35.180.250310.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)13079-6"},{"key":"2026061001301405000_35.180.250310.9","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.211.3.r99jn03657"},{"key":"2026061001301405000_35.180.250310.10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.100.5.1328"},{"key":"2026061001301405000_35.180.250310.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2006.05.002"},{"key":"2026061001301405000_35.180.250310.12","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.219.2.r01ma07510"},{"key":"2026061001301405000_35.180.250310.13","doi-asserted-by":"publisher","DOI":"10.3978\/j.issn.2072-1439.2015.01.36"},{"key":"2026061001301405000_35.180.250310.14","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-006-0152-2"},{"key":"2026061001301405000_35.180.250310.15","doi-asserted-by":"publisher","DOI":"10.1186\/s13643-021-01626-4"},{"key":"2026061001301405000_35.180.250310.16","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.d5928"},{"key":"2026061001301405000_35.180.250310.17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1398-9995.2009.01973.x"},{"key":"2026061001301405000_35.180.250310.18","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1097\/LBR.0000000000000920","article-title":"Reporting standards for diagnostic testing: guidance for authors from editors of respiratory, sleep, and critical care journals","volume":"; 30","author":"Ost","year":"2023","journal-title":"J Bronchol Interv Pulmonol"},{"key":"2026061001301405000_35.180.250310.19","unstructured":"Chandler J , Cumpston M , Thomas J , et al.
