OBJECTIVES
To identify the most cited articles in general surgery published by Brazilian authors.
INTRODUCTION
There are several ways for the international community to recognize the quality of a scientific article. Although controversial, the most widely used and reliable methodology to identify the importance of an article is citation analysis.
METHODS
A search using the Institute for Scientific Information citation database (Science Citation Index Expanded) was performed to identify highly cited Brazilian papers published in twenty-six highly cited general surgery journals, selected based on their elevated impact factors, from 1970 to 2009. Further analysis was done on the 65 most-cited papers.
RESULTS
We identified 1,713 Brazilian articles, from which nine papers emerged as classics (more than 100 citations received). For the Brazilian contributions, a total increase of about 21-fold was evident between 1970 and 2009. Although several topics were covered, articles covering trauma, oncology and organ transplantation were the most cited. The majority of classic studies were done with international cooperation.
CONCLUSIONS
This study identified the most influential Brazilian articles published in internationally renowned general surgery journals.
目的
确定巴西作者发表的普通外科领域最具引用价值的文章。
简介
国际社会有多种方法可以认可科学文章的质量。尽管存在争议，但最广泛使用且可靠的方法是引文分析，用于确定文章的重要性。
方法
使用科学信息研究所引文数据库（科学引文索引扩展版）进行检索，以确定在 1970 年至 2009 年期间，从 26 种高引用率的普通外科期刊中选择的、具有高影响力因子的 26 种期刊中，发表的巴西高引用率论文。对 65 篇最具引用价值的论文进行了进一步分析。
结果
我们共确定了 1713 篇巴西文章，其中有 9 篇被认为是经典之作（被引用超过 100 次）。1970 年至 2009 年，巴西的相关文献数量增加了约 21 倍。虽然涵盖了多个主题，但创伤、肿瘤学和器官移植领域的文章引用率最高。大多数经典研究都有国际合作。
结论
本研究确定了发表在国际知名普通外科期刊上的最具影响力的巴西文章。
