How COVID changed surgical acute inflammatory diseases and surgeons clinical practice during the first wave of COVID-19

Abstract

BackgroundAnecdotal evidence suggests that community infection control measures during the COVID-19 outbreak have modified the number and natural history of acute surgical inflammatory processes (ASIP - appendicitis, cholecystitis, diverticulitis and perianal abscesses) admissions. This study aims to evaluate the impact of the COVID-19 pandemic on the presentation and treatment ASIP and quantify the effect of COVID-19 infection on the outcomes of ASIP patients. MethodsThis was a multicentre, comparative study, whereby ASIP cases from March 14th to May 2nd 2019 acted as historical controls for the cohort of patients with the same pathology during the COVID-19 pandemic. Data regarding patient and disease characteristics as well as outcomes, were collected from sixteen centres in Madrid, and one in Seville (Spain).ResultsThe number of patients treated for ASIP in 2019 was 822 compared to 521 in 2020. This reduction occurs mainly in patients with mild cases, while the number of severe cases was similar. ConclusionsThe number of ASIP cases treated during the pandemic was reduced by more than one third mainly due to a dramatic reduction in mild cases. This also has represented a selection of severe cases. We also found a more conservative approach to the patients this year, non-justified by clinical circumstances.The positive COVID-19 status itself did not have a direct impact on either morbidity or mortality. This is an interesting finding which if confirmed through future research with a larger sample size of COVID-19 positive patients, can expedite the recovery phase of acute surgical services.
