Tracheal stenosis remains a challenge in the thoracic surgery field. Recognizing the hot topics and major concepts in this area would help the health policy makers 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 authors' and countries' contributions.
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 keywords, 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.
The majority of articles were limited to case series and retrospective studies. The studies had been conducted less frequently on prevention, risk 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 scientific progress in this field. The highest degree of cooperation occurred between the USA and England with 15 common papers.
Most of the published literature in tracheal stenosis research field 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 families' well-being.
气管狭窄仍是胸外科领域的一项挑战。了解该领域的热点话题和主要概念将有助于卫生政策制定者确定自身优先事项并设计有效的研究计划。本研究分析并梳理了气管狭窄研究的主题和趋势随时间的变化，以及作者和国家的贡献。
使用Bibexcel获取检索结果。为确定冷门和热门话题，运用共现分析，使用“科学网”“PubMed”和“Scopus”这三个国际数据库。通过VOSviewer和NetDraw对文章中的不同类别，如关键词、作者和国家进行了探索。之后，通过十个共现术语描绘了1945年至2015年四个时间区间内研究主题的趋势。
大多数文章局限于病例系列和回顾性研究。对预防、危险因素和发病率测定的研究较少，而对治疗和手术操作的研究广泛。根据科学网索引的文章，45个国家和8260名作者为该领域的科学进步做出了贡献。美国和英国之间的合作程度最高，有15篇共同发表的论文。
气管狭窄研究领域已发表的大多数文献是关于手术和非手术治疗。开展筛查和预防研究将减轻这种疾病对卫生系统的负担，以及对患者及其家庭福祉的影响。
