[Clinical practice guideline for laparoscopic radical resection of intrahepatic cholangiocarcinoma(2026)]

Intrahepatic cholangiocarcinoma (ICC) is highly aggressive and prone to lymph node metastasis or invasion of adjacent bile ducts, blood vessels, and organs. In recent years, reports on laparoscopic radical resection for ICC have increased annually, demonstrating short-and long-term outcomes comparable to those of open surgery. However, further standardization is still required in areas such as surgical indications, major hepatectomy or resection in difficult anatomical locations, combined resection of bile ducts, blood vessels, or multiple organs, and surgery following conversion or downstaging therapy. To this end, the Branch of Biliary Surgery, Chinese Society of Surgery, Chinese Medical Association and the Biliary Surgery Expert Working Group of Surgical Branch, Chinese Medical Doctor Association convened domestic experts to formulate recommendations on key issues, encompassing surgical safety and efficacy, preoperative evaluation and indications, operative procedures, lymph node dissection and hepatectomy, combined resection of bile ducts, blood vessels, or organs, and conversion/downstaging surgery. This initiative aims to provide guidance for the standardized implementation of laparoscopic radical resection for ICC.
