The rapid spread of coronavirus disease 2019 (COVID-19) has attracted worldwide attention. There were also reported gastrointestinal symptoms in patients with COVID-19. This work aims to analyze the global research trends in COVID-19 and digestive disease.
The related papers on COVID-19 and digestive disease were identified with Pubmed and web of science core collection on September 3, 2021. Bibliometric visualization was conducted through VOSviewer and CiteSpace.
The analytic research was based on original articles and reviews. There were 997 articles found, with citations ranging from 0 to 878. These articles were distributed among 86 countries and 355 journals. The USA mainly contributed (288 articles), where 3 of the top 10 institutions were located. Followed by China (215 articles) and Italy (160 articles). The highest level of scientific collaboration has been formed between the USA to China. The World Journal of Gastroenterology (39 papers) published the most significant number of articles. Concerning the research topic, the colon/small bowel had the largest number of articles, followed by the liver and pancreaticobiliary. "Liver injury," "inflammatory bowel disease," "management," and "endoscopy" were the hotspot keywords. The largest cluster of liver transplantation had offered hints regarding research frontiers.
The analytic results showed that the liver, especially liver transplantation, and inflammatory bowel disease were the 2 most influential research topics in COVID-19 and digestive disease.
2019 年冠状病毒病（COVID-19）的迅速传播引起了全球关注。也有报道称 COVID-19 患者存在胃肠道症状。本研究旨在分析 COVID-19 与消化疾病的全球研究趋势。
于 2021 年 9 月 3 日通过 Pubmed 和 web of science 核心合集检索 COVID-19 与消化疾病相关文献。通过 VOSviewer 和 CiteSpace 进行文献计量可视化分析。
分析研究基于原始文章和综述，共检索到 997 篇文章，引用次数从 0 到 878 次。这些文章分布在 86 个国家和 355 种期刊上。美国主要贡献（288 篇文章），其中前 10 名机构中有 3 家来自美国。其次是中国（215 篇文章）和意大利（160 篇文章）。美国与中国之间形成了最高水平的科学合作。《世界胃肠病学杂志》（39 篇文章）发表的文章数量最多。就研究主题而言，结肠/小肠的文章数量最多，其次是肝脏和胰胆。“肝损伤”、“炎症性肠病”、“管理”和“内镜”是热点关键词。最大的肝移植聚类提示了研究前沿。
分析结果表明，肝脏，特别是肝移植和炎症性肠病，是 COVID-19 与消化疾病中最具影响力的 2 个研究主题。
