A polyglycolic acid (PGA) sheet or oxidized regenerated cellulose (ORC) mesh can therefore be used for additional coverage after thoracoscopic surgery, and this study compared the clinical impacts of these two materials. Methods: From 2018 to 2020, 262 thoracoscopic surgeries for primary SP were performed, of which 125 patients were enrolled in this study, and 48 and 77 patients received ORC and PGA coverage, respectively. The clinical characteristics and surgical procedures were reviewed, and the recurrence rates were compared. To obtain more comprehensive evidence, we performed a literature review and meta-analysis comparing ORC and PGA coverage. Results: There were no significant differences in patient characteristics between the two groups. Operating time was slightly shorter in the ORC group than in the PGA group (p = 0.008). The pneumothorax recurrence rate was similar in both groups (PGA: 10.4%, ORC: 6.2%, p = 0.529), but the recurrence-free interval was significantly longer (p = 0.036) in the ORC (262 days) than in the PGA (48.5 days) group. The literature review identified three relevant studies, and the meta-analysis revealed no difference in pneumothorax recurrence rate between the two coverage materials. Conclusions: The two visceral pleural coverage materials, PGA and ORC, did not show significant differences in postoperative pneumothorax recurrence. Therefore, if applied appropriately, the choice of material between ORC and PGA for thoracoscopic pneumothorax surgery does not have a significant impact on the clinical outcome.<\/jats:p>","DOI":"10.3390\/jcm12113705","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T16:17:33Z","timestamp":1685204253000},"page":"3705","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Oxidized Regenerated Cellulose versus Polyglycolic Acid for Pleural Coverage in Pneumothorax Surgery"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0053-4470","authenticated-orcid":false,"given":"Wongi","family":"Woo","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul 06273, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bong Jun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, National Health Insurance Service Ilsan Hospital, Goyang 10444, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1388-2471","authenticated-orcid":false,"given":"Duk Hwan","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul 06273, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Du-young","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Kangbuk Samsung Hospital, Sungkyunkwan University College of Medicine, Seoul 03181, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8998-9510","authenticated-orcid":false,"given":"Sungsoo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul 06273, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tae Yun","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Kangbuk Samsung Hospital, Sungkyunkwan University College of Medicine, Seoul 03181, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1136\/thoraxjnl-2014-206577","article-title":"Epidemiology of spontaneous pneumothorax: Gender-related differences","volume":"70","author":"Bobbio","year":"2015","journal-title":"Thorax"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"666","DOI":"10.1136\/thorax.55.8.666","article-title":"Epidemiology of pneumothorax in England","volume":"55","author":"Gupta","year":"2000","journal-title":"Thorax"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"e028624","DOI":"10.1136\/bmjopen-2018-028624","article-title":"Epidemiology and medical service use for spontaneous pneumothorax: A 12-year study using nationwide cohort data in Korea","volume":"9","author":"Kim","year":"2019","journal-title":"BMJ Open."},{"key":"ref_4","first-page":"1379","article-title":"Incidence of spontaneous pneumothorax in Olmsted County, Minnesota: 1950 to 1974","volume":"120","author":"Melton","year":"1979","journal-title":"Am.
