Background: The use of bibliometrics can help us identify the most impactful articles on a topic or scientific discipline and their influence on clinical practice. We aimed to identify the 100 most cited articles covering esophageal motility disorders and examine their key characteristics.
Methods: The Web of Science database was utilized to perform the search, using predefined search terms. The returned dataset was filtered to include full manuscripts written in the English language. After screening, we identified the 100 most cited articles and analyzed them for title, year of publication, names of authors, institution, country of the first author, number of citations and citation rate.
Results: The initial search returned 29,521 results. The top 100 articles received a total of 20,688 citations. The most cited paper was by Inoue et al. (665 citations) who first described peroral endoscopic myotomy (POEM) for treating achalasia. The article with the highest citation rate was the third version of the Chicago Classification system, written by Kahrilas and colleagues. Gastroenterology published most papers on the list (n=32) and accrued the highest number of citations (6,675 citations). Peter Kahrilas was the most cited author (3,650 citations) and, along with Joel Richter, authored the highest number of manuscripts (n=14). Most articles were produced in the USA (n=66) between the years 1991 and 2000 (n=32).
Conclusions: By analyzing the most influential articles, this work is a reference on the articles that shaped our understanding of esophageal motility disorders, thus serving as a guide for future research.
