ABSTRACT
Acute appendicitis is one of the most common general surgical emergencies worldwide; however, its diagnosis remains challenging, with a high proportion of negative appendicectomies. The purpose of this study was to investigate the benefit of routine use of pre-operative imaging for the evaluation of suspected appendicitis. This retrospective cohort study included all cases of appendicectomies performed for suspected acute appendicitis during the first and second peaks of the COVID-19 pandemic, between March 2020 and February 2021. The control group included all cases of appendicectomies performed for suspected acute appendicitis in the previous 12 months (March 2019-February 2020). One hundred and four patients underwent appendicectomy in the study group, compared to 209 in the control group, with similar gender distribution but a significantly higher median age in the study group (33 vs. 28, p = 0.001). The two groups had similar rates of perforation and similar median white cell count (WCC) and CRP. Imaging was used in 80.77% of the patients in the study group, compared to 61.72% in the control group (p = 0.001), with 55.77% of patients in the study group undergoing CT scans. Despite this, the negative appendicectomy rate (NAR) in the two groups did not differ significantly (11.54% vs. 15.79%, p = 0.320). The increase in the use of imaging for the diagnosis of acute appendicitis during the COVID-19 pandemic did not lead to a significantly lower negative appendicectomy rate. Registration The study was pre-registered at ClinicalTrials.gov (NCT05205681).
