BackgroundRetraction of previously published scientific articles is an important mechanism to preserve the integrity of scientific work. This study analyzed retractions of previously published articles from surgery journals.MethodsWe searched for retracted articles in the 100 surgery journals with the highest SJR2 indicator grades.ResultsWe found 130 retracted articles in 49 journals (49%). Five or more retracted articles were published in 8 journals (8%). The mean time between publication and retraction was 26 months (range 1 to 158 months). The United States, China, Germany, Japan, and the United Kingdom accounted for more than 3 out of 4 of the retracted articles. The greatest number of retractions came from manuscripts about orthopedics and traumatology, general surgery, anesthesiology, cardiothoracic surgery, and plastic surgery. Nonsurgeons were responsible for 16% of retractions in these surgery journals. The main reasons for retraction were duplicate publication (42%), plagiarism (16%), absence of proven integrity of the study (14%), incorrect data (13%), data published without authorization (12%), violation of research ethics (11%), documented fraud (11%), request of an author(s) (5%), and unknown (3%). In 25% of the retracted articles, other publications by the same authors also had been retracted.ConclusionRetraction of published articles does not occur frequently in surgery journals. Some form of scientific misconduct was present in the majority of retractions, especially duplication of publication and plagiarism. Retractions of previously published articles were most frequent from countries with the greatest number of publications; some authors showed recidivism.Copyright © 2018 Elsevier Inc.
