Postoperative Outcomes in Surgical Coronavirus Disease 2019 Patients: A Retrospective Cohort Study.

Purpose: Patients infected with severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) who require surgical procedures are likely to experience higher postoperative mortality and morbidity. Our objective was to evaluate the perioperative course of patients infected with SARS-COV-2 undergoing surgical procedures. The purpose of this study was to describe the characteristics, outcomes, and the effect of the presence of symptoms.
