OBJECTIVE: We aimed to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on the incidence of intussusception.

MATERIALS AND METHODS: Literature search of the PubMed and EMBASE databases was conducted for articles published in English until August 5, 2022.

RESULTS: Overall, 127 articles were retrieved, and five studies from South Korea (n=4) and the United States of America (n=1) containing clinical data from single-center medical records to nationwide databases were ultimately included in the systematic review. All the included studies reported that the incidence of intussusception decreased significantly during the pandemic period compared with the pre-pandemic period. The communicable disease incidence tended to decrease even as the incidence of non-communicable diseases did not significantly change. There was no significant difference in the time to diagnosis between the pre-pandemic and pandemic periods; however, the time to radiologic reduction was significantly longer or not depending on the study.

CONCLUSIONS: The COVID-19 pandemic significantly reduced the incidence of intussusception in children, supporting the hypothesis that infection plays a major role in the etiology of intussusception. Future studies in the late pandemic or post-pandemic era, which would represent the level of implementation of non-pharmaceutical interventions and social distancing as well as additional data from various countries will be needed.
