An Overview of Tracheal Stenosis Research Trends and Hot Topics

Background: Tracheal stenosis remains a challenge in the thoracic surgery . Recognizing the hot topics and major concepts in this area would help the health policy to determine their own priorities and design the effective research plans. The present study analyzed and mapped the topics and trends of tracheal stenosis studies over time as well as authorsand countriescontributions. Materials and Methods: Search results were obtained employing Bibexcel. To determine cold and hot topics, co-occurrence analysis was applied using three international databases 'Web of Science', 'PubMed' and 'Scopus'. Appropriately, different categories in the articles such as , authors, and countries were explored via VOSviewer and NetDraw. Afterward, the trends of research topics were depicted in four time-intervals from 1945 to 2015 by ten co-occurrence terms. Results: The majority of articles were limited to case series and retrospective studies. The studies had been conducted less frequently on prevention, factors and incidence determination but extensively on treatment and procedures. Based on the articles indexed in WOS, 45 countries and 8,260 authors have contributed to progress in this . The highest degree of cooperation occurred between the USA and England with 15 common papers. Conclusions: Most of the published literature in tracheal stenosis research was about surgical and non-surgical treatments. Conducting the screening and prevention studies would diminish the burden of this disease on the health system as well as the patients and their familieswell-being.
