A Global Bibliometric Analysis of the Top 100 Most Cited Articles on Early Thoracotomy and Decortication in Pleural Empyema.

Most pleural empyema cases are linked to pneumonia, a substantial fraction of patients present with empyema without any association to pneumonia. The occurrence of empyema caused by tuberculosis (TB) is increasing in regions where TB is prevalent. In May 2024, a bibliometric analysis was conducted involving the screening of 7,620 articles sourced from Google Scholar. Google Scholar was selected for its comprehensive nature, encompassing articles indexed in prominent databases like Web of Science, Scopus, and PubMed. This allowed access to significant studies that might be overlooked if they were not indexed by these databases. Articles were selected based on their citation count and specific inclusion criteria, focusing on early thoracotomy and decortication in pleural empyema. Two authors (VB and MK) independently conducted a thorough screening and data collection. The hundred top articles published from 1945 to 2015, garnered a total of 16,928 citations. These articles were written by 93 distinct first authors from 22 countries and 83 institutions, and were featured in 35 journals. The primary categories of literature included those describing the disease characteristics, features, causes, and types of pleural empyema, as well as various treatment modalities and management strategies, each constituting 37% of the literature. Additionally, pediatric empyema was a focus in 11% of the articles. The present analysis highlights publication trends, identifies gaps in the literature, and suggests areas for future research, serving as a valuable resource for guiding upcoming studies on early thoracotomy and decortication in pleural empyema.
