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.
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.
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.
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.
在冠状病毒大流行期间，尽管自发性气胸（SP）的研究数量有所增加，但文献中对此的文献计量研究还不够充分。本研究旨在分析发表的关于 SP 的科学文章。
从 Web of Science 数据库中获取 1980 年至 2021 年间发表的关于 SP 的研究，并使用统计和文献计量学方法进行分析。采用 Spearman 相关系数进行相关性研究。使用指数平滑估计器预测未来几年的发表趋势。网络可视化地图用于分析引文并确定热门话题。
共发现 2422 篇出版物。其中 1403 篇（57.9%）为文章。近年来，关于 SP 的文章呈非线性增长趋势。文献的前 5 大贡献者是美国（231，16.4%）、日本（161，11.4%）、英国（98，6.9%）、法国（81，5.7%）和中国台湾（78，5.5%）。最活跃的 3 个机构是国立台湾大学医院（22，1.5%）、韩国天主教大学（19，1.3%）和国立台湾大学（19，1.3%）。发表文章最多的 3 种期刊是《胸腔》（51 篇）、《胸外科年鉴》（46 篇）和《胸科疾病杂志》（45 篇）。研究最多的主题是原发性 SP、复发、胸腔镜、胸膜固定术、电视辅助胸腔镜手术、COVID-19、电视辅助胸腔手术、胸腔引流管和继发性自发性气胸。根据趋势主题分析，近年来研究的关键词是 COVID-19、胸腔引流管、肺炎、皮下气肿、危险因素、呼吸困难、原发性 SP、FLCN 基因、张力性气胸、单端口、术后复发、继发性自发性气胸、慢性阻塞性肺疾病和单端口。
在这项全面的文献计量学研究中，我们总结了 1403 篇关于 SP 的文章，这些文章在 COVID-19 大流行期间呈数量递增趋势。本文通过总结与 SP 相关的全球研究，包括 COVID-19 大流行期间的研究，可为临床医生和科学家提供有用的资源。
