To explore and establish a China-specific same-day surgery model for hepatectomy based on the enhanced recovery after surgery (ERAS) concept, and to promote the clinical practice and standardized application of same-day surgery for hepatectomy in China. Organized by the Minimally Invasive Surgery Committee and Intelligent Medicine Committee of the Chinese Research Hospital Association, multidisciplinary experts in hepatobiliary surgery, anesthesiology, and nursing, integrating literature evidence with clinical practice, deliberated on key clinical issues encompassing the establishment of a same-day surgery system for hepatectomy, process management, patient selection and assessment, perioperative multimodal management, discharge criteria, and follow-up monitoring, leading to the formulation of this expert consensus. The consensus specifies the qualification requirements for hospitals and surgeons performing same-day surgery for hepatectomy, establishes a multidimensional patient selection system based on pathological, physiological, psychological, and social support dimensions, standardizes whole-course management strategies covering operative technical essentials, perioperative anesthetic management, multimodal analgesia and antiemesis, and early discharge assessment, and clarifies principles for post-discharge follow-up and emergency management. The formulation of this consensus provides a basis for safety margins and quality assurance in same-day surgery for hepatectomy, and holds significant practical value and exemplary significance for advancing the alignment of China′s liver surgery practices with international standards, unlocking the potential of high-quality medical resources, and improving patients′ experience during treatment.
