Timing of hepatectomy following the Omicron variant infection for vaccinated-patients:A retrospective cohort study

作者： Wu-Gui Yang Yu-Fu Peng Yu-Bo Yang Bo Li Yong-Gang Wei Fei Liu Division of Liver surgery Department of General SurgeryWest China HospitalSichuan UniversityChengdu 610041China

Many previous studies suggested that severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection elevated the risk of morbidity and 90-day mortality after operation, especially pulmonary complications [1–7]. Uncertainty about perioperative safety puts off the progress of elective surgery [8]. The Omicron variant has recently become the dominant variant causing prevalence in several countries [9]. Although a high rate of patients with Omicron presented asymptomatic status [10], it is still unclear whether Omicron infection would raise the risk of postoperative complications.
