Changing characteristics of emergency surgery during COVID-19 pandemic: a retrospective cohort study

Background: In other countries, researchers have noticed diverse variations in the features of patients undergoing emergency surgery during the COVID-19 pandemic. In Mexico, there is not information about this issue. Methods: Workers of the Mexican Government, who required emergency surgeries were studied by the general surgery service of a General Hospital administered by the Institute of Social Security and Services for State Workers Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE), through the periods from March-August 2019 (non-exposed) and March-August 2020 (exposed). The analysis included: demographic data, laboratory information, post-operative diagnoses, symptoms’ length, days of emergency stay, and post-operative stay. Results: One hundred and ninety-three emergency surgeries were analyzed; 106 in 2019 and 87 in 2020 (a decrease of 18%). Throughout the pandemic, the number of days between the symptoms’ onset and surgery was greater: 2019, 7.6 ± 4.6 days; 2020, 14 ± 6.7 days (p < 0.0001). In addition, cases of acute appendicitis decreased (2019-60.3%; 2020-42.5%), and those of acute calculous cholecystitis increased (2019-12.2%; 2020-24.1%). Conclusion: Through the COVID-19 pandemic, there were notable changes in the characteristics of Mexican Government’s workers who warranted emergency surgery.
