PURPOSE Appendicitis is the most common surgical emergency in children. This study aims to examine how the COVID-19 pandemic affected pediatric patients with acute appendicitis with regards to presentation and complications. METHODS After obtaining ethics approval, we performed a chart review of pediatric patients admitted with a diagnosis of appendicitis from March 1, 2019 to June 30, 2019 and March 1, 2020 to June 30, 2020. Data collection included a post-operative period of 30 days. The primary outcome of interest was complication rates post-appendectomy. Secondary outcomes included time to presentation, symptoms, time to surgery, and rate of perforation. RESULTS Overall, 205 patients were included with 115 in the pre-pandemic group and 90 in the pandemic group. There was no significant difference in complication rates (16% pre-pandemic vs. 13.3% pandemic). In the pandemic group, time from symptom onset to presentation was significantly longer (1.87 days vs. 2.42 days, p = 0.01), more patients presented with emesis (70% vs. 55%, p<0.05), more patients had perforated appendicitis (47% vs. 32%, p<0.05), more patients were likely to be tachycardic (46% vs. 32%, p = 0.05)  and waited less time for surgery (5.75 h vs. 4.15 h, p = 0.05) which both approached significance. CONCLUSION Significant delays in pediatric appendicitis presentation, and higher rates of tachycardia and perforation were seen during the pandemic. This did not result in increased complication rates but could suggest pandemic patients were more ill than their pre-pandemic counterparts.
