Global research trends in endoscopic breast surgery: a bibliometric analysis from 1994 to 2024

Endoscopic breast surgery (EBS) is designed to reduce surgical trauma and optimize cosmetic outcomes through inconspicuous incisions. However, a comprehensive understanding of the evolution of research focus in EBS is lacking. This study aimed to analyze global publication trends, academic impacts, and evolving research directions in the field of EBS. The Web of Science Core Collection database was searched for publications related to EBS from database inception to December 31, 2024. Bibliometrix, CiteSpace, VOSviewer, and Scimago Graphica were utilized to analyze publication and citation trends, contributive countries, prolific institutions, influential authors, significant journals, and research hotspots. Among the 2074 publications initially identified, 333 met the inclusion criteria. The number of annual publications grew exponentially post-2019. China, South Korea, and the United States dominated research productivity, with Changhua Christian Hospital as the top institution. Lai HW was the most influential author, and Aesthetic Plastic Surgery was among the leading journals. Keyword analysis revealed a focus on endoscopic nipple-sparing mastectomy, breast reconstruction, and oncological safety. Research hotspots shifted from feasibility evaluations to advanced reconstructive techniques and robot-assisted surgeries. Research on EBS has undergone significant evolution over the past three decades. This study provides valuable insights into the current research landscape and development trends in EBS, offering guidance to researchers, clinicians, and policymakers to promote the field and improve patient outcomes. Priority should be given to future research evaluating long-term oncological safety, cost-effectiveness, and the implementation of large-scale multicenter trials to establish standardized protocols and evidence-based practices.
