[Hepato-pancreato-biliary surgery should strive to achieve the "Four Standards"]

In order to better standardize the implementation of the operation, the authors put forward a new concept of "four-standard surgery" in hepato-pancreato-biliary surgery, namely, determination, search, calibration and optimization. The concept of "four-standard surgery" standardizes the resection scope and modulates surgical approach through the determination, search and calibration of key anatomical markers. With the deepening understanding of anatomy and tumor biological behavior, as well as the development and update of surgical techniques and equipment, the anatomical markers and surgical approaches of surgery are constantly optimized. It is hoped that through the promotion and application of the concept of "four-standard surgery", hepato-pancreato-biliary surgeons can improve their understanding and mastery of surgery, facilitate the standardization and modeling of surgery, and thus ultimately enable patients to obtain better treatment outcomes from high-quality and high-standard surgery.
