Abstract:Intrahepatic cholangiocarcinoma (ICC) is a highly aggressive malignant tumor, and lymph node metastasis is one of the most important adverse prognostic factors for ICC patients. Lymph node dissection has important value in lymph node staging, prognostic guidance, and adjuvant therapy for ICC. In recent years, domestic and foreign scholars have conducted in-depth research on ICC lymph node metastasis and dissection. However, there are still different understandings and recommendations regarding ICC lymph node dissection based on different research results and consensus at home and abroad. At the same time, the scope, number, and methods of lymph node dissection vary, leading to slight differences in corresponding research results. This article provides an overview of issues related to ICC lymph node dissection, including the scope, number, method, clinical value, appropriate population, and prospective clinical research based on recent research findings, aiming to clarify the research hotspots, focus, and difficulties in this field, and to help improve the comprehensive treatment level of ICC.
