The impact of the COVID-19 pandemic on the number of patients presenting with appendicitis to the emergency department.

Introduction: The COVID-19 pandemic has had an influence on the number of patients presenting to the emergency department (ED) with surgical conditions.

Aim: To evaluate the number of patients presenting with acute appendicitis (AA) and the percentage of complicated appendicitis before and after the COVID-19 disease outbreak.

Material and methods: This is a retrospective study based on the data of all patients presenting with AA to the ED of a tertiary COVID referral university hospital in Greece. We analysed the number of patients treated with AA, patient characteristics, and the proportion of patients with complicated appendicitis, and we compared the 2 groups of patients treated 12 months before and 12 months after COVID-19 onset in Greece.

Results: A total of 152 patients were included in this study. There was a significant decrease in the number of patients presenting with AA after COVID-19 onset in Greece. Respectively, 91 and 61 patients were subjected to appendectomy 12 months before and after COVID-19 onset. Comparing the 2 groups of patients, there was a statistically significant increase in the operation time (p = 0.01) after COVID-19 onset, whereas the percentage of complicated appendicitis, the duration of symptoms before presenting to the ED (< 24 h, > 24 h), and the type of operation (laparoscopic, open, converted) did not differ significantly between the 2 groups of patients.

Conclusions: The number of patients presenting to the ED with AA decreased after COVID-19 onset, most likely because patients hesitated to seek help in a COVID-19 referral hospital.
