Abstract: Driven by the policies of government to promote day surgery, inguinal hernia day surgery has developed rapidly in China, yielding significant social and economic benefits. However, due to the vast territory and considerable regional disparities in China, the technical and management development of day surgery remains highly uneven. To effectively evaluate the outcomes and ensure quality control of inguinal hernia day surgery, and to facilitate its further nationwide promotion, the Hernia and Abdominal Wall Ambulatory Surgery Expert Group of China Ambulatory Surgery Alliance, in collaboration with relevant institutions, organized domestic experts in hernia and abdominal wall surgery day surgery. Based on literature and the practical situation of its domestic promotion, they developed the Expert guideline on standardized process and standards of ambulatory surgery for inguinal hernia (2026 edition), aiming to provide a better reference and foundation for establishing standardized and uniform procedures for inguinal hernia day surgery.
