Background: This study investigated whether there was a change in acute appendicitis, appendicectomy admissions or disease severity during the 2020 lockdown period in NSW.

Methods: A retrospective before-and-after study was undertaken of patients admitted to two Sydney hospitals (St. Vincent's and Liverpool Hospitals) who had appendicectomy for presumed acute appendicitis and patients who had confirmed appendicitis but did not undergo surgery. Study periods were the 2020 lockdown period (15 March-15 May 2020), the corresponding period in the previous year, and the 1-month after these periods. Patients were classified as having no, mild or severe appendicitis using operation and histopathological reports.

Results: (Thirty-six percent) fewer patients were admitted with acute appendicitis during the lockdown period compared with the previous year with a substantial reduction in normal/mild appendicitis presentations (OR 0.56, 95% CI 0.34-0.93, P = 0.03). There were 46% fewer patients with mild appendicitis during lockdown (56) compared with the previous year (103); numbers of patients with severe appendicitis were very similar (46 vs. 51). There was no increase in number of admissions with severe appendicitis, or in the time from onset of symptoms to admission, in the month following lockdown.

Conclusion: Compared with the previous year, there were markedly fewer admissions with appendicitis during lockdown, with no evidence of a shift to more cases of severe appendicitis nor delayed presentation in the post-lockdown period. It is plausible that some patients with mild appendicitis may have recovered without hospitalization, supporting the importance of implementing trials on non-surgical management of appendicitis.

Omental infarction is a rare cause of acute abdomen, often mimicking more common abdominal emergencies such as appendicitis and cholecystitis, presenting significant diagnostic challenges. A 47-year-old male with a history of ulcerative colitis underwent laparoscopic total colectomy with end ileostomy. Postoperatively, he developed severe abdominal pain, chills, nausea, and increased abdominal distension.

Ultrasound is a first-line and often preferred imaging modality in the diagnosis of acute appendicitis. When the appendix is not visualised during a dedicated appendix ultrasound study, patients may require a CT study, which uses ionising radiation, or undergo conservative clinical observation with the inherent risk of clinical deterioration, perforation and sepsis. Median baseline data, at our hospital imaging department, revealed a rate of combined normal and abnormal appendix visualisation of 34.
