Acute pancreatitis (AP) is a common digestive disease encountered in Emergency Departments that carries a heavy socioeconomic burden. This study was conducted to determine the global status of AP research. Articles related to AP published in 1999 to 2018 were retrieved from the Web of Science (WOS) database and the 20 highest-output countries or regions were determined based on the total number of publications. Correlation analysis of AP research output and the gross domestic product (GDP) of each country or region was conducted. The quantity and quality of research of these 20 highest-output countries were compared to the total output, outputs per capita, and average impact factor (IF). All annual data were analyzed using time-trend analysis. A keyword co-occurrence analysis was conducted to determine the highlights in AP research. In total, 17,698 publications were retrieved, and 16,461 papers (93.0%) of them were from the 20 highest-output countries. A significantly positive correlation was identified between AP research output and the GDP (R = 0.973, P < .001). The 5 highest-output countries were the USA (24.9%), China (12.3%), Germany (7.5%), Japan (6.7%), and the UK (6.1%). Finland ranked 1st in the number of publication per capita, the USA had the highest accumulated IF (25,432.758) and total citations (104,592), Switzerland had the highest average IF (6.723), and Netherland had the highest average citations (51.90). Genetic research and AP-related hyperglycemia were research highlights. Analysis of the global output of research of AP research showed signs of growth. Research output was positively correlated with GDP. For the most productive countries, research quality was stable. Although developing countries lagged behind in output per capita and quality, great progress has been made in the past 2 decades.
急性胰腺炎（AP）是急诊科常见的一种消化系统疾病，给社会经济带来了沉重的负担。本研究旨在确定全球 AP 研究的现状。从 Web of Science（WOS）数据库中检索了 1999 年至 2018 年发表的与 AP 相关的文章，根据发表文章总数确定了 20 个发表文章最多的国家或地区。对各国或地区的 AP 研究产出与国内生产总值（GDP）进行了相关性分析。比较了这 20 个产出最高的国家或地区的研究产出数量和质量与总产出、人均产出和平均影响因子（IF）。所有年度数据均采用时间趋势分析进行分析。通过关键词共现分析确定 AP 研究的重点。共检索到 17698 篇文献，其中 16461 篇（93.0%）来自 20 个产出最高的国家或地区。AP 研究产出与 GDP 呈显著正相关（R=0.973，P<.001）。产出最高的 5 个国家分别为美国（24.9%）、中国（12.3%）、德国（7.5%）、日本（6.7%）和英国（6.1%）。芬兰的人均发文量排名第一，美国的累积 IF（25432.758）和总引文量（104592）最高，瑞士的平均 IF 最高（6.723），荷兰的平均引文量最高（51.90）。遗传研究和 AP 相关高血糖是研究的重点。对全球 AP 研究产出的分析显示出增长的迹象。研究产出与 GDP 呈正相关。对于最具生产力的国家，研究质量较为稳定。尽管发展中国家在人均产出和质量方面落后，但在过去 20 年中取得了巨大的进步。
