Abstract

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a global pandemic that can cause diarrhoea, nausea/vomiting, and abdominal pain, among other gastrointestinal (GI) symptoms.

AIM

To perform a bibliometric analysis of the global research production pertaining to GI involvement in COVID-19.

METHODS

The Scopus database was used to search the global literature on GI involvement in COVID-19 during 2020. A bibliometric review of these publications was also performed using VOSviewer.

RESULTS

Scopus had published 95615 documents on COVID-19 in all areas of research at the time of data collection. In total, 1267 publications on the topic of GI and COVID-19 were identified. Research articles (n = 606; 47.83%), letters (293; 23.13%), and reviews (186; 14.68%) were the most popular types of documents. The most productive countries and institutions in this field were the United States and Huazhong University of Science and Technology. The most cited paper was Xiao et al, which was published in Gastroenterology as a brief communication, with 798 citations. This paper provides evidence for GI infection of COVID-19 and its possible faecal–oral transmission route. In the term cluster analysis, there were two frontiers in this field: GI manifestations among COVID-19 patients and the implications of COVID-19 for the gastroenterologist.

CONCLUSION

GI manifestations among COVID-19 patients and implications of COVID-19 for gastroenterologists were of interest, especially in the early stages of the pandemic.

Keywords: COVID-19; Gastrointestinal; Symptoms; Bibliometric; Scopus

Core Tip: This bibliometric analysis provides the first concise summary of global gastrointestinal (GI) publications related to coronavirus disease 2019 (COVID-19). It highlights the benefits of bibliometric analysis in a systematic and structured way to measure the productivity of studies. GI manifestations among COVID-19 patients and the implications of COVID-19 for gastroenterologists were of interest, especially in the early stage of the pandemic. The results will form the basis for future research and guide decision-making in research related to GI symptoms and treatments in COVID-19.
