Objective:

The objective of the study was to evaluate the effect of COVID-19 on the outcomes of surgical patients and the factors associated with postoperative complications and mortality.

Methods:

The study included hospitalized patients with similar demographic and clinical features, who underwent similar surgical operations with a positive polymerase chain reaction test for SARS CoV-2 before or within days following the surgery (COVID-19 group) and a control group was formed of patients who tested negative for COVID-19. The two groups were compared in terms of demographic, clinical, and laboratory data, the presence of pneumonia, complications, and 30-day post-operative mortality.

Results:

The diagnosis for COVID-19 increased the risk of complications and mortality. Age, CRP, D-dimer, ASA Grade 3-4, > 2 comorbidities, and pneumonia were determined to be factors increasing the risk of complications. Age, CRP, > 2 comorbidities, emergency operations, and pneumonia were determined to increase the risk of mortality.

Conclusion:

As patients with peri/post-operative COVID-19 positivity might be at increased risk of postoperative complications and mortality, emergency surgery in infected cases should be delayed in appropriate cases.
