Liver transplantation is the most effective curative treatment for end-stage liver disease. In recent years, with the advancements in surgical techniques, immunosuppressive regimens and perioperative management, patient survival rates have significantly improved. However, postoperative infection remains a major complication affecting graft function and long-term survival of recipient. Bacterial infections are the most common among them. Epidemiological studies showed that approximately 55% of liver transplant recipients develop infections within one year post-operation, and the one-year survival rate of infected recipients is significantly reduced. Therefore, it is crucial to strengthen the prevention, early diagnosis, and standardized treatment of bacterial infections after liver transplantation. Based on the latest domestic and international evidence-based medical evidence and clinical practice, this consensus aims to provide the guidance for the comprehensive, whole-course and refined management of bacterial infections following liver transplantation.
