Top 100 Most-Cited Articles on Enhanced Recovery After Surgery: A Bibliometric Analysis and Visualized Study

Abstract

BackgroundThe enhanced recovery after surgery (ERAS) protocol is widely implemented in surgeries, and this study aims to reveal the characteristics of the 100 most-cited original articles in the field of ERAS research.MethodsThe literature was retrieved in the Web of Science database, the 100 most-cited original articles were identified, and their characteristics were analyzed, including the trends of publications and citations; contributions from countries, institutions, and authors; co-cited authors and journals in the references; served surgeries, research endpoints, keywords; and the level of evidence.ResultsThere was a rising trend in the yearly publications and citations. Denmark and the USA contributed the largest number of highly cited papers. The University of Copenhagen was the most influential institution. Kehlet, Henrik was the most influential author. The British Journal of Surgery was the most often published and cited journal. ERAS protocols were overwhelmingly implemented in colorectal surgeries. The most focused endpoints were “length of stay”, “complications”, and “readmission”. The most frequently used keywords were “fast track”, “length of stay”, and “laparoscopy”. The keyword “enhanced recovery after surgery” burst since 2012. More than half of the highly cited articles presented level IV evidence, but there was no correlation between citations (densities) and the levels of evidence.ConclusionsThe highly cited research overwhelming implemented ERAS in colorectal surgeries, the “length of stay” was the most focused element, and Kehlet, Henrik was the most influential researcher. Most of the highly cited ERAS had low levels of evidence, and the total number of citations was not relevant to the level of evidence. Therefore, studies with high levels of evidence are still required in the future.

Bibliometric and visual analysis of intraoperative hypotension from 2004 to 2022

“…The free sharing of a wide range of scientific results on the Internet has transformed all aspects of bibliometric practice, including data collection, infrastructure, definitions, and metrics collection. Bibliometric methods can be used to explore the impact of research areas, researchers, and specific papers, or to mine the literature for impact or scholarly value in each research area ( 10 – 13 ).Bibliometric analysis has been applied to medical fields such as stroke ( 12 ), ERAS ( 13 ), and anesthesiology ( 14 ). However, there are still relatively few bibliometric studies on IOH.…”

Grand challenges in visceral surgery

“…Endoluminal surgery has made it possible to carry out advanced interventions without the need for resecting segments of the gastrointestinal canal ( 1 ). Enhanced recovery has greatly reduced the physiological impact of surgery on the patient ( 2 ). Modern hernia surgery focuses not only on closing the hernial defect but also maintaining abdominal wall function.…”
