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.
To systematically explore the impact of the pandemic in the management of ACD.
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).
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.
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.
Core Tip: Acute colonic diverticulitis is one of the most common conditions encountered by surgeons in the acute setting. As a result of the pandemic, elective surgery and in-patients’ visits have been cancelled or postponed worldwide. Conservative strategies for surgical diseases, such as acute appendicitis and acute cholecy
