Top 100 cited articles related to EUS: A bibliometric analysis

Area of Science:

• Bibliometrics and Medical Informatics
• Gastroenterology and Endoscopy
• Oncology and Diagnostic Imaging

Background:

• Citation analysis is crucial for assessing scientific impact in biomedical fields.
• Endoscopic ultrasound (EUS) is a significant diagnostic and therapeutic tool.
• Identifying highly cited EUS articles highlights key advancements and research trends.

Purpose of the Study:

• To identify and analyze the 100 most cited articles in the field of endoscopic ultrasound (EUS).
• To evaluate the characteristics and thematic focus of influential EUS research.
• To understand the evolution of EUS applications over time.

Main Methods:

• A comprehensive search of the Web of Science Core database was conducted using terms related to endoscopic ultrasound.
• The top 100 cited articles were identified based on citation counts.
• Article characteristics including publication year, authors, journals, impact factor, countries, institutions, article type, topic, and evidence grade were analyzed.

Main Results:

• The 100 most-cited EUS articles were published between 1988 and 2018, with a median citation count of 240.5.
• Research predominantly focused on diagnostic performance (80%) and interventional therapy (20%).
• Key topics included fine-needle aspiration (FNA) diagnostic accuracy, tumor diagnosis, EUS transluminal drainage, and pancreatic diseases (especially pancreatic cancer and solid masses).

Conclusions:

• The analysis highlights EUS-guided FNA, tumor staging, and transluminal drainage as major advances in EUS over the past 35 years.
• Pancreatic diseases, particularly cancer and solid masses, are the most researched areas in EUS.
• There is a significant increase in research articles focusing on the therapeutic applications of EUS.
