Research trends and performances of breast reconstruction: a bibliometric analysis

BACKGROUND: The need for postmastectomy breast reconstruction surgery has increased dramatically, and significant progress has been made both in implant and autologous based breast reconstruction in recent decades. In this paper, we performed a bibliometric analysis with the aim of providing an overview of the developments in breast reconstruction research and insight into the research trends. METHODS: We searched the Science Citation Index Expanded database and the Web of Science Core Collection for articles published between 1991 to 2018 in the topic domain, using title, abstract, author keywords, and KeyWords Plus. Four citation indicators TCyear, Cyear, C(0) and CPP(year) were employed to help analyse the identified articles. RESULTS: The number of scientific articles in breast reconstruction in this period steadily increased. It took most articles nearly a decade to hit a plateau in terms of citation counts. Plastic and Reconstructive Surgery, Annals of Plastic Surgery, and Journal of Plastic Reconstructive and Aesthetic Surgery published the largest number of articles on breast reconstruction. Nine of the top ten most prolific publications were based in the USA. The research highlights related to breast reconstruction were implant-based breast reconstruction, deep inferior epigastric perforator (DIEP) flap breast reconstruction, and superficial inferior epigastric artery (SIEA) flap breast reconstruction. CONCLUSIONS: This bibliometric analysis yielded data on citation number, publication outputs, categories, journals, institutions, countries, research highlights and tendencies. It helps to picture the panorama of breast reconstruction research, and guide the future research work.
