Decreased incidence of intussusception during the COVID-19 pandemic. Trends in pediatric surgical emergencies

Purpose Recent reports suggest that the COVID-19 pandemic may be influencing disease morbidity. The purpose of this study was to investigate pandemic-related changes in the incidence of pediatric surgical emergencies. Methods Data from patients with one of 8 typical conditions considered to be pediatric emergencies who presented at 3 hospitals close to central Tokyo were collated retrospectively from accident and emergency (AE) department records for 2020 and compared with data for 3 years prior to 2020. Results All subjects had similar demographic profiles. The total number of pediatric AE attendances from 2017 to 2020 was 2880 (2017: n = 600, 2018: n = 736, 2019: n = 817, and 2020: n = 727). Annual attendances were similar. Of the 8 conditions, there were significantly less cases of intussusception in 2020 than previously (23/727; 3.1% versus 132/2153; 6.1%) p
