Article:

Coronavirus 2019 disease (COVID-19) has created major impacts on public health. The virus has plagued a large population requiring hospitalization and resource utilization. Knowledge about the COVID-19 virus continues to grow. It can commonly present with gastrointestinal symptoms; initially, this was considered an atypical presentation, which led to delays in care. The pandemic has posed serious threats to the care of anorectal diseases. Urgent surgeries have been delayed, and the care of cancer patients and cancer screenings disrupted. This had added to patient discomfort and the adverse outcomes on healthcare will continue into the future. The better availability of personal protective equipment to providers and standard checklist protocols in operating rooms can help minimize healthcare-related spread of the virus. Telehealth, outpatient procedures, and biochemical tumor marker tests can help with mitigation of anorectal-disease-related problems. There is limited literature about the clinical management of anorectal diseases during the pandemic. We performed a detailed literature review to guide clinicians around management options for anorectal disease patients. We also highlighted the health challenges seen during the pandemic.
