Bibliometric analysis of 40 most cited articles comparing video-assisted thoracic surgery and robotic-assisted thoracic surgery in lung cancer (1997–2021)

BACKGROUND: In recent years, conventional thoracoscopic surgery has been accepted as the traditional treatment method in the non-small cell lung cancer (NSCLC). VATS and RATS, which are the techniques of this surgical method, have been increasing their effectiveness and applicability of late years. The aim of this bibliometric analysis is to evaluate the importance and efficiency of articles comparing VATS and RATS techniques. MATERIALS AND METHODS: Studies comparing VATS and RATS published between 1997 and 2021 were identified in the Web of Science database (accessed on 31. 12. 2021). The 40 most cited studies were analyzed in terms of publication years, country of study, authors, institutions that the authors were affiliated with, journal, journal address and impact factor. RESULTS: While an article was cited a maximum of 187 times when the citations made by the authors were excluded from the analysis, it was observed that all publications were cited a total of 1946 times. It was seen that an average of 51. 30 ± 47. 73 (8–187) articles were cited. In the 25-year, the highest number of publications was reached in 2019, while eight articles were published this year. The Annals of Thoracic Surgery (n = 13, 32. 5 %) was the journal in which the articles in the list were published the most. Most of the articles in our study (n = 31, 77.5 %) were published in US journals. While many studies presented more than one topic and analysis, the topic of most interest in 19 (47.5 %) studies was postoperative complications. CONCLUSION: This bibliometric analysis reflects important and qualified articles comparing VATS and RATS technique in thoracic surgery, but it can also be used to explain or explain the performance and results of these techniques, their positive and negative aspects, and their superiority over each other.
