Managing appendicitis during the COVID-19 era: A single centre experience & implications for future practice

Aim During the COVID-19 pandemic, emergency surgery was modified in line with Royal College guidance to accommodate the evolving climate. This study compared management of appendicitis before and during the pandemic by assessing disease presentation severity, modes of investigation, surgical management and patient outcomes. Outcomes assessed included length of stay, readmissions and rates of postoperative wound infections. Methods We collected data on appendicitis patients managed at a district general hospital over two distinct 8-week periods; 42 patients before and 36 patients during the COVID-19 pandemic respectively. The study included clinically or radiologically diagnosed appendicitis patients. Results Our study found patients during the COVID-19 pandemic had higher inflammatory markers (CRP 103 vs 53 mg/L; p = 0.03) and more severe disease on histological examination of the appendix than pre-pandemic. Patients were nearly twice as likely to undergo CT diagnosis of appendicitis during the pandemic than before. During the pandemic, only half of the cohort underwent laparoscopic appendicectomy in contrast with greater than 85% of the pre-COVID-19 cohort (p = 0.0005). Patients in the COVID-19 era cohort recorded shorter lengths of hospital stay (2.6 vs 3 days; p = 0.35); however, had higher reattendance rates (12 vs 25%; p = 0.15) and surgical site infections (p = 0.0443). Finally, the study reported shorter median time to theatre (0 vs 1 days) during the pandemic than before. Conclusion In addition to reiterating the benefits of laparoscopic versus open surgery and quicker diagnostic methods, this study also implies that though patients during COVID-19 era presented with more severe disease, their treatment was in a more efficient service.
