Background: This study analyzed the impact of the coronavirus disease 2019 (COVID-19) pandemic on acute appendicitis (AA) treatment in Korea, a country that did not implement lockdown measures. Methods: A retrospective analysis was conducted during two discretionary time periods: a pre COVID-19 period, and a COVID-19 period. This study included adult and pediatric patients diagnosed with AA who underwent surgical treatment. Clinical and laboratory parameters, changes in surgery timing, disease severity, and postoperative outcomes were compared between the pre and post pandemic periods. Results: The study included a total of 221 patients, with 139 receiving appendectomy in the COVID-19 cohort and 82 in the control cohort. In patients without fever, operative time was significantly longer during the COVID-19 period (p<0.01). Among patients presenting with fever, the rate of complicated AA was higher during the COVID-19 period than in the control period (p<0.01). During the COVID-19 period, the diagnostic and preoperative delay times, as well as postoperative hospital stays, were longer (p<0.05), and the incidence of postoperative complications and other hospital diagnoses was higher (p<0.01) during the COVID-19 period than in the control period. Multivariate analysis showed that age (p=0.03) and the presence of fever (p<0.01) were independent risk factors for complicated AA. Conclusions Older patients and those with fever were at greater risk of severe AA. During outbreaks of infectious diseases like COVID-19, careful consideration is needed regarding surgical interventions in older patients with fever. Understanding vulnerabilities is crucial for disease management in the future.

Objective: This study compared the incidence of suicide cases among Korean students before and after the coronavirus disease-2019 (COVID-19) pandemic. Methods: Aggregated case reports of all known suicide victims attending elementary, middle, and high school in South Korea from 2017 to 2022 were analyzed. These reports, compiled by teachers under the directive of the South Korean Department of Education, surveyed the circumstances surrounding each suicide and identified associated risk factors posthumously. Results: The completed suicide rate was 2.37 per 100,000 students pre-COVID-19 (2017–2019), significantly increasing to 3.37 per 100,000 students post-COVID-19 (2020–2022; odds ratio [OR] 1.42, p<0.001). The rate began to rise approximately 6 months into the pandemic and continued to worsen throughout 2021 and 2022. Fair attendance significantly increased in 2020 (74.83%, p=0.003) during the initial stage of school closure measures compared to 2019 (58.27%) among students prior to suicide completion. However, as social distancing measures continued, “absence due to medical reasons” showed a significant increase in 2022 (23.56%) compared to 2019 (13.67%, p=0.025) and 2020 (9.52%, p<0.001) among these students. Among those who completed suicide, teachers reported increased signs of depression and anxiety posthumously compared to pre-COVID-19 periods. Conclusion The incidence of completed suicide among students was significantly higher in the post-COVID-19 years compared to pre-COVID-19. Attendance records and teachers’ reports indicated a deterioration in mental health among these students before suicide completion, highlighting the need to consider mental health impacts when implementing future quarantine policies.
