Core Tip
Core tip: The aim of this study was to summarize the incidence of perineural invasion (PNI) in hilar cholangiocarcinoma (HCCA), and provide the distribution of nerve plexuses around hepatic portal to clinical surgeons. Totally 75 patients with HCCA were investigated to summarize the incidence and modes of PNI. Sections of hepatoduodenal ligament from 5 autopsy cases were scanned to display the distribution of nerve plexuses around hepatic portal. The overall incidence of PNI in this study was 92% and three nerve plexuses in the hepatoduodenal ligament and Glisson’s sheath were classified and they all surrounded the great vessels very closely. PNI is grossly underreported in HCCA and it should be considered when stratifying HCCA patients for further adjuvant treatment.
