RESUMEN
ABSTRACT: The prevalence of children exhibiting coronavirus disease 2019 (COVID-19) with digestive system involvement remains unknown. Therefore, we aimed to quantify the impact of COVID-19 on the digestive system of children.In this meta-analysis, we searched PubMed, Embase, and Web of Science from January 1, 2020, to June 31, 2020. We also searched for COVID-19 publications in specific journals for more comprehensive results. We included studies that reported the epidemiological and clinical characteristics of COVID-19, and we excluded duplicate publications, reviews, animal studies, case reports, publications without the full text, studies with incomplete information, and studies from which data extraction was impossible.We conducted a meta-analysis of the incidence of gastrointestinal symptoms and changes in liver function involving 19 studies. The pooled prevalence of diarrhea was 10% (95% CI: 7-14; I2â =â84%), that of nausea or vomiting was 7% (95% CI: 5-11; I2â =â77%), and that of abdominal pain was 4% (95% CI: 2-9; I2â =â79%). In addition, the pooled incidence of increased alanine aminotransferase was 8% (95% CI: 5-15; I2â =â46%), and the pooled incidence of increased AST was 15% (95% CI: 9-26; I2â =â66%). The pooled rate of recovery was 97% (95% CI: 94-100; I2â =â86%), and the pooled rate of death, which was 1% (95% CI: 1-4; I2â =â48%), was much smaller than the recovery rate.Our research shows that digestive system symptoms and function in children with COVID-19 are not uncommon. More attention should be paid to this unique group of patients.

The outbreak of novel coronavirus pneumonia in 2019 (Coronavirus disease 2019 [COVID-19]) is now threatening global public health. Although COVID-19 is principally defined by its respiratory symptoms, it is now clear that the virus can also affect the digestive system. In this review, we elaborate on the close relationship between COVID-19 and the digestive system, focusing on both the clinical findings and potential underlying mechanisms of COVID-19 gastrointestinal pathogenesis.
