SP4.1.14 Single centre experience in managing acute appendicitis during COVID-19 pandemic

Abstract Background Given the pressure of COVID pandemic, the UK Intercollegiate guidance encouraged a move towards non-operative or open appendicectomy management of acute appendicitis. The aim of the study was to assess the approaches used to manage acute appendicitis and their outcomes during pandemic peak and after it. Methods This was a single-centre retrospective study, 2-observer data collection. We collected and analysed data on acute appendicitis management approaches (surgical and non-surgical) and patient outcomes were compared during the peak of the pandemic (04-2020 to 06-2020) and post-peak (07-2020 to 09-2020) periods. Results 190 patients - (peak – 88, F:M=1.09, median age – 30.5) and post-peak 102 (F:M=1.12, median age -31)). There were no significant differences for APPY risk score, ASA grade, comorbidities between the groups. There was more diagnostic imaging performed during the peak of the pandemic (peak 71.6%, post-peak – 56.9%) (p = 0.035 X2=4.431). Comparison between managing patients during peak and post-peak showed that approaches were the following: conservative (14.8% vs 14.7%, P = 0.998), laparoscopic appendicectomy (65.3% vs 96.6% P = <0.001), open appendicectomy (34.7% vs 3.4% P = <0.001). There was no significant difference in postoperative complications (Clavien-Dindo II-IIIb), readmission to hospital, or total LoS (median=3 days) between the groups (p > 0.05). Median LoS for patients treated conservatively was 1 day. Only 1 patient developed COVID postoperatively, the mortality was 0%. Conclusions Treatment strategies adapted and modified in COVID peak were effective and safe in managing acute appendicitis. Laparoscopic surgery remained a safe practice even in the peak of COVID pandemic.

Abstract Introduction The COVID-19 pandemic has influenced the delivery of healthcare. In accordance with the UK Joint Royal Colleges’ advice the management of acute appendicitis (AA) changed with greater consideration for non-operative management (NOM) or open appendicectomy where operative management (OM) s sought. Our aim is to share our experience of the presentation, management and outcomes for patients presenting to our Trust with AA to guide care for future viral pandemics. Methods This single-centre retrospective cohort study included patients diagnosed with AA in March to July 2019 compared with March to July 2020. Medical records were used to evaluate demographics, inflammatory markers, imaging, severity, management, histology, length of stay (LOS), complications and 90-day outcomes. Results There were 149 and 125 patients in the 2019 and 2020 cohort, respectively. 14 patients (9.4%) had NOM in 2019 versus 31 patients (24.8%) in 2020 (p = 0.001). In the 2019 OM group 125 patients (92.6%) had laparoscopic appendicectomy versus 69 (73.4%) in 2020. 59 patients (39.6%) had a CT in 2019 versus 70 (56%) in 2020. The median LOS was 4 days (interquartile range (IQR) 3 to 6 days) in 2019 and 3 days (IQR 2 to 5 days) in 2020 (p = 0.03). Two patients in each year who received NOM had treatment failure (14.3% in 2019 and 6.5% in 2020). Three patients in 2019 who had OM had treatment failure (2.2%). Of 95 patients tested for COVID-19 all but one was negative. Conclusion During the COVID-19 pandemic there was no observed increase in severity of AA, patients had a shorter LOS and were more likely to have imaging. NOM proportionally increased with no observed change in outcomes.
