Hepatitis C virus infection in patients undergoing surgery in a single tertiary academic center

Background and Aim: Lack of awareness disturbs proper care for hepatitis C virus (HCV) infections in patients undergoing surgery. We investigated the status of HCV screening, confirmation, and treatment in patients who underwent surgery. Methods: Patients who underwent surgery at a tertiary academic center between 2019 and 2021 were eligible for this retrospective study. Results: Between 2019 and 2021, 96 894 patients (40 121 males; 41.4%) who underwent surgery under general anesthesia were recruited. The median age of the participants was 55.0 years. Of the 83 920 (86.6%) patients who tested positive for anti-HCV antibodies, 576 (0.7%) showed positive results, with a higher proportion of patients with diabetes mellitus (32.6% vs 18.5%), hypertension (50.5% vs 28.6%), liver cirrhosis (13.2% vs 1.7%), and unfavorable laboratory test results when compared with those with negative results (all P < 0.05). HCV RNA was tested in 215 patients (37.3%), with a positivity rate of 20.5% (n = 44). Of the 44 patients, 42 (95.5%) were referred for antiviral treatment, and 29 (69.0%) were successfully treated with direct-acting antiviral therapy. HCV RNA confirmation rates were higher in the Department of Hepatobiliary and Transplant Surgery (76.6%) than in the other surgical departments (25.0-33.5%) (P < 0.001). Conclusions: The proportion of patients who were positive for anti-HCV antibodies and failed to receive proper management after surgery was not negligible. Increased awareness of HCV infection among surgeons through appropriate education may be required.
