目的分析2003—2009年《中华胃肠外科杂志》发表临床随机对照试验（RCT）论文情况。方法研究2003—2009年《中华胃肠外科杂志》42期期刊刊载的临床RCT文献，对每篇文献收稿时间、发表时间、引文总数、中文引文数、英文引文数、文章所属单位、单（或多）中心研究情况、研究阳性结论情况、研究中患者例数、基金资助情况、研究起始时间、研究结束时间、研究作者人数等指标进行分析。结果2003—2009年《中华胃肠外科杂志》共刊出临床RCT文章80篇，期均RCT数1．6篇．RCT在所有临床研究类文献中占比为12％。80篇RCT研究的平均发文时滞为208d，篇均引文数为8．6条，篇均研究对象数为118例（名），篇均研究周期为29．2个月。RCT研究中多中心研究7篇．单中心研究73篇．所有RCT研究均得出有阳性意义的结论。有基金资助的RCT研究17篇，占所有临床RCT数的21-3％。南京军区南京总医院发表临床RCT研究6篇，是最多的单位。结论《中华胃肠外科杂志》重视刊载循证依据极强的临床RCT研究，此类研究对国内胃肠外科领域临床指南及诊疗规范的制定具有重要意义。

Objective To study the academic level of randomized controlled trials （RCT） published in the Chinese Journal of Gastrointestinal Surgery between 2003 and 2009. Methods Published RCTs in the 42 issues of the Chinese Journal of Gastrointestinal Surgery was searched for relevant articles published between 2003 and 2009. Data extracted for analysis included the time at manuscript received, publication time, total number of citations, number of citations in Chinese, number of citations in English, author＇s affiliations, single- or multi- center study, positive conclusions from RCTs, number of patients recruited in RCTs, research funding source, the start time, the finish time and the number of authors in RCTs. Results During the past seven years, a total of 80 clinical RCTs were published in the Chinese Journal of Gastrointestinal Surgery, accounting for 12% of all the clinical studies published in the journal, and the average number of RCTs in each issue was 1.6. The average delay time before publication was 208 days. The total number of citations and the total number of patients in RCTs were 685 and 9402. The average number of citations, the average number of patients recruited in each RCT, and the average research period in RCTs were 8.6, 118 and 29.2. There were 7 multi-center studies, and the number of single-center study was 73. All the RCT studies had significant conclusions, and 17 （21.3%） RCT studies were funded. Nanjing general hospital of Nanjing military command had the largest number of RCTs（n=6）. Conclusion The Chinese Journal of Gastrointestinal Surgery puts emphasis on clinical studies of high evidence level such as RCT, which provide evidence for making the clinical guidelines in the specialty of gastrointestinal surgery.
