Effects of Preoperative COVID-19 Status on Emergent or Urgent Colectomy Outcomes
Abstract
Objectives: Severe acute respiratory syndrome coronavirus 2 has been described as eliciting a powerful immune response. The association of coronavirus disease 2019 (COVID-19) infection with diseases requiring emergent or urgent colectomies may exacerbate the risk of surgical complications. We investigated the effect of preoperative COVID-19 infection on the clinical outcomes of patients who underwent a nonelective colectomy in 2021.Methods: We queried the American College of Surgeons National Surgical Quality Improvement Program Targeted Colectomy database for all of the patients who underwent a colectomy in 2021 and filtered for patients classified as “Urgent” or “Emergent.” Two groups were created based on preoperative COVID-19 status: COVID+ (n = 242) and COVID− cohorts (n = 11,049). Several clinical variables were compared.
Results: Before filtering for urgent/emergent operations, a large percentage of COVID+ patients were found to have undergone an urgent or emergency colectomy (68.36% vs 25.05%). Preoperatively, these patients were more likely to be taking steroids (21.49% vs 12.41%) or have a bleeding issue requiring a transfusion (19.42% vs 11.00%). A larger percentage of infected patients returned to the operating room (14.05% vs 8.13%) and had a hospital stay >30 days (18.18% vs 5.35%). COVID-19 infection was associated with a higher rate of mortality (14.05% vs 8.08%) but did not independently predict it (odds ratio 1.25, P = 0.233), with all P ≤ 0.001.
Conclusions: Urgent or emergent colectomy patients who were COVID-19+ preoperatively were more likely to present with comorbidities, which, along with the recent viral infection, contributed to markedly worse clinical outcomes, including an increased rate of mortality.
