Identification of Hepatic Lymphatic Drainage in Intrahepatic Cholangiocarcinoma using Laparoscopic Tracer Technique

Injecting indocyanine green into the Glisson pedicle in a patient with intrahepatic cholangiocarcinoma allowed accurate tracing of hepatic lymphatic drainage area during laparoscopic surgery. The technique enabled identification and dissection of regional lymph nodes, providing a potential method for precise lymph node mapping in liver cancer surgery.
