How Does the COVID-19 Pandemic Affect Pediatric Patients with Intussusception Treated by Ultrasound-Guided Hydrostatic Enema Reduction?

BACKGROUND

The pandemic of COVID-19 has significantly influenced the epidemiology of intussusception. Nevertheless, the effects of the COVID-19 pandemic on the operation of ultrasound-guided hydrostatic enema reduction (USGHER) for intussusception have been largely unknown.

METHODS

The data of pediatric patients with intussusception who were treated by USGHER from January to March of 2019 (Control Group), 2020 (Study Group 1), and 2021 (Study Group 2) in a large Chinese medical institution were retrospectively collected and analyzed.

RESULTS

We enrolled 246 patients, including 90 cases in Control Group, 70 in Study Group 1, and 86 in Study Group 2 ( = 0.042). The time from the onset of symptoms to the hospital visit and the time from the hospital visit to performing the ultrasound in Study Group 1 was significantly longer than that in Control Group and Study Group 2 ( = 0.036, = 0.031, respectively). The number of patients with bloody stool and the longest invaginated length of intussusception in Study Group 1 increased significantly compared with patients in the other two groups ( = 0.007, = 0.042, respectively). Comparisons of neither the pressure of enema nor the time of duration when performing USGHER present statistical significance among the three groups ( = 0.091, = 0.085, respectively). For all enrolled pediatric patients, there was no perforation case involved, and recurrence of intussusception occurred in few cases.

CONCLUSIONS

Besides the negative impacts on the incidence of intussusception, the COVID-19 pandemic might have led to the diagnostic delay of intussusception and the deterioration of patients' clinical manifestations, but it did not significantly affect the operation of USGHER and patients' clinical outcome.
