[Interpretation of Chinese expert consensus on function-preserving grstrectomy for gastric cancer(2025 edition)]

With continuous advancements in medical technology, the increasing detection rate of early gastric cancer, and the growing emphasis on postoperative quality of life among both patients and physicians, function-preserving gastrectomy (FPG) has emerged as a critical surgical approach. In May 2021, the publication of Chinese expert consensus on function-preserving gastrectomy for gastric cancer (2021)" (hereafter referred to as the "Consensus") marked the first systematic elaboration of the definition, indications, and surgical techniques of FPG in China, thereby facilitating its standardized implementation nationwide. In recent years, the rapid evolution of emerging technologies such as functional visualization, lymph node mapping, vascular navigation, and artificial intelligence has further refined the conceptual framework and clinical applications of FPG. Concurrently, the release of pivotal clinical research findings has provided high-level evidence to inform key therapeutic strategies within FPG. Against this backdrop, we convened a panel of leading experts in the field to update and expand the "Consensus" by integrating recent advancements in research and clinical practice. The revised version includes 13 specific recommendations, further enhancing its value as a practical guide for clinical decision-making. This article aims to provide an in-depth interpretation of the updated recommendations outlined in the revised "Consensus."
