Abstract

Abstract: Background: During coronavirus pandemic, despite the increase in the number of studies on spontaneous pneumothorax (SP), there is not enough bibliometric study in the literature. In this study, it was aimed to analyze scientific articles published on SP. Methods: Studies published on SP between 1980 and 2021 were obtained from the Web of Science database and analyzed using statistical and bibliometric methods. Spearman correlation coefficient was used for correlation studies. The exponential smoothing estimator was used to forecast publication trend for coming years. Network visualization maps were used to analyze citations and identify trending topics. Results: A total of 2422 publications were found. 1403 (57.9%) of these publications were articles. The articles on SP have increased with a non-linear trend in recent years. The top 5 contributors to the literature were USA (231, 16.4%), Japan (161, 11.4%), United Kingdom (98, 6.9%), France (81, 5.7%), and Taiwan (78, 5.5%). The top 3 most active institutions were National Taiwan University Hospital (22, 1.5%), Catholic University Korea (19, 1.3%), and National Taiwan University (19, 1.3%). The top 3 journals that published the most articles were Chest (51), Annals of Thoracic Surgery (46), and Journal of Thoracic Disease (45). The most studied subjects were primary SP, recurrence, thoracoscopy, pleurodesis, video-assisted thoracoscopic surgery, COVID-19, video-assisted thoracic surgery, chest tube(s), and secondary spontaneous pneumothorax. According to trend topics analysis, the keywords studied in recent years are COVID-19, chest tubes, pneumonia, subcutaneous emphysema, risk factors, dyspnea, primary SP, FLCN gene, tension pneumothorax, uniportal, postoperative recurrence, secondary spontaneous pneumothorax, chronic obstructive pulmonary disease, and uniportal. Conclusion: In this comprehensive bibliometric study, we summarized 1403 articles about SP, which has an increasing trend in the number of articles during the COVID-19 pandemic process. This article can be a useful resource for clinicians and scientists through presenting a summary of worldwide studies related to SP, including the ones during COVID-19 pandemic.
