P118 The 134-year-old problem meets the 1-year-old problem: lessons learned in managing acute appendicitis during the COVID era

INTRODUCTION: The Right Iliac Fossa Pain Treatment (RIFT) study highlighted the rate of negative appendicectomies in the UK as one third of all procedures. However, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2/COVID) pandemic has changed surgical practice. New practices in the COVID era have changed the rate of negative appendicectomies. METHODS: A retrospective analysis was conducted of patients admitted with appendicitis from March 2020 to June 2020. PATIENT DEMOGRAPHICS: 58 patients were identified, 43 (74%) were adults and 15 (26%) were children. The median age of the adults was 33 (range 18-80) and the median American Society of Anaesthetists (ASA) grading was 1. The median age of children was 11 (range 4-17) and all were ASA grade 1. RESULTS: 73.8% (31) of adult patients had a Computerised Tomography (CT) scan as part of their workup. 40% of paediatric patients underwent an ultrasound scan of the abdomen whilst the remaining 60% were diagnosed clinically. The open approach was favoured in both cohorts (39.5% and 46.7% respectively). No negative appendicectomies were performed. CONCLUSION: COVID19 has changed practice resulting in better outcomes for colorectal units. Further studies (COVID SURG and COVID HAREM) are needed to fully assess the role of imaging in reducing the number of negative appendicectomies.
