The subcommittee on the Assessment of Korean Gastroenterology Research Achievements of the Korean Society of Gastroenterology (KSG) conducted a survey of SCI papers in the fields of gastroenterology to evaluate the current status of Korean gastroenterology research. A total of 4,260 papers were confirmed as gastroenterology papers published by researchers affiliated with Korean medical institutions during the 1974-2006 periods. Among those 4,260 papers, 2,373 papers were authored by the members of the KSG. The first Korean gastroenterology SCI paper was published in 1981 and the Korean SCI gastroenterology publication output dramatically increased since 1995. Sixty three institutions published SCI papers and 14 institutions published more than 100 SCI papers. Sixteen members of KSG published more than 20 SCI papers as reprint authors. Ninety percent of Korean gastroenterology papers was cited at least once. KSG member reprint author papers were cited an average of 4.1 times within 3 years after publication. Korean gastroenterology research achievements over the last 30 years show a remarkable growth in terms of quantity and quality. The KSG members have played central roles in these progresses, and it is anticipated that they will continue to do so in the future.
