Abstract
Traditional biliary surgery equated precision with technical mastery, focusing on flawless dissection and minimizing immediate complications. This article describes a fundamental paradigm shift in how surgical precision is defined. We argue that precision is evolving from technical execution to a comprehensive strategy driven by long-term patient outcomes. The analysis begins by examining limitations of the technique-centric approach. It then details the new paradigm's multidimensional aspects, including preoperative planning, intraoperative function preservation, and tailored postoperative care. The discussion addresses key technologies and conceptual innovations enabling this shift, concluding with future directions. Redefining precision is critically important. It guides personalized therapy, optimizes resource allocation, and advances biliary surgery toward improving long-term quality of life.
