[Interpretation of "Guideline for quality control of laparoscopic radical resection for biliary tract cancer（2026 edition）"].

The publication of "Guideline for quality control of laparoscopic radical resection for biliary tract cancer（2026 edition）" marks the transition of laparoscopic radical resection for biliary tract cancer from technical exploration to a developmental stage centered on stratified indications, team credentialing, and whole-process quality control. The clinical value of laparoscopic radical resection for biliary tract cancer should not be evaluated solely by minimally invasive benefits, but should be established on the basis of strict patient selection, standardized margin assessment, adequate regional lymphadenectomy, high-quality biliary or gastrointestinal reconstruction, and standardized postoperative quality feedback. Focusing on the core recommendations of the guideline across different biliary tract cancer subtypes, this article provides in-depth interpretation of indication selection and team credentialing criteria, quality assessment of intraoperative margin control and lymph node dissection, as well as controversial issues such as the timing of surgery after conversion therapy and the choice of surgical procedures for mid-bile duct cancer. The aim is to promote the standardized, cautious, and high-quality implementation of laparoscopic radical resection for biliary tract cancer.
