Core Tip

Core Tip: The overall survival (OS) from surgically resectable intrahepatic cholangiocarcinoma remains poor. Lymph node dissection is increasingly being performed in the setting of hepatic resection with the aims of improving patient outcomes such as OS, minimising recurrence, as well as for accurate staging. However, no consensus exists in the literature regarding its use for these purposes. This systematic review and meta-analysis of hepatic resection with and without lymph node dissection for surgically resectable intrahepatic cholangiocarcinoma was performed with the primary outcome measures of OS and disease-free survival.
