ABSTRACT
Background: Acute appendicitis (AA) is one of the most common emergencies in general surgery worldwide. During the pandemic, a significant decrease in the number of accesses to the emergency department for AA has been recorded in different countries. A systematic review of the current literature sought to determine the impact of Coronavirus Disease 2019 (COVID-19) on hospital admissions and complications of AA. Method: A systematic search was undertaken to identify repeated cross-sectional studies reporting the management of AA during the COVID-19 pandemic (index period) as compared to the previous year, or at the turn of lockdown (reference period). Data were abstracted on article (country of origin) and patients characteristics (adults, children [i.e. non adults, <18-year-old]), or mixed population) within the two given timeframes, including demographics, number of admissions for AA, number of appendectomies, and complicated appendectomies. Results: Of 201 full-text articles assessed for eligibility, 54 studies from 22 world countries were included. In total, 27 (50%) were conducted on adults, 12 (22%) on children, and 15 (28%) on a mixed patients population. The overall rate ratio of admissions for AA between the two periods was 0.94 (95%CI, 0.75-1.17), with significant differences between studies on adults (0.90 [0.74-1.09]), mixed population (0.50 [0.27-0.90]), and children (1.50 [1.01-2.22]). The overall risk ratio of complicated AA was 1.65 (1.32-2.07), ranging from 1.32 in studies on children, to 2.45 in mixed population. Conclusion: The pandemic has altered the rate of admissions for AA and appendectomy, with parallel increased incidence of complicated cases in all age groups.
ABSTRACT
BACKGROUND: Acute colonic diverticulitis (ACD) is common in Western countries, with its prevalence increasing throughout the world. As a result of the coronavirus disease 2019 (COVID-19), elective surgery and in-patients' visits have been cancelled or postponed worldwide. AIM: To systematically explore the impact of the pandemic in the management of ACD. METHODS: MEDLINE, Embase, Scopus, MedxRiv, and the Cochrane Library databases were searched to 22 December 2020. Studies which reported on the management of patients with ACD during the COVID-19 pandemic were eligible. For cross sectional studies, outcomes of interest included the number of hospital admission for ACD, as well as key features of disease severity (complicated or not) across two time periods (pre- and during lockdown). RESULTS: A total of 69 papers were inspected, and 21 were eligible for inclusion. Ten papers were cross sectional studies from seven world countries; six were case reports; three were qualitative studies, and two review articles. A 56% overall decrease in admissions for ACD was observed during lockdown, peaking 67% in the largest series. A 4%-8% decrease in the rate of uncomplicated diverticulitis was also noted during the lockdown phase. An initial non-operative management was recommended for complicated diverticulitis, and encouraged to an out-of-hospital regimen. Despite initial concerns on the use of laparoscopy for Hinchey 3 and 4 patients to avoid aerosolized contamination, societal bodies have progressively mitigated their initial recommendations as actual risks are yet to be ascertained. CONCLUSION: During the COVID-19 pandemic, fewer patients presented and were diagnosed with ACD. Such decline may have likely affected the spectrum of uncomplicated disease. Established outpatient management and follow up for selected cases may unburden healthcare resources in time of crisis.
