Abstract
PURPOSE: The aim of this study was to assess the efficacy of combined resection and reconstruction (CRR) of the hepatic artery (HA) in surgery for hilar cholangiocarcinoma (HC). MATERIALS AND METHOD: Among 172 patients who underwent surgical resection for HC, the following three groups were defined according to the type of vascular reconstruction: VR(-) group, in which neither CRR of the portal vein (PV) nor HA was performed (n = 74); VR-PV group, in which only CRR of the PV was required (n = 54); and VR-A group, in which CRR of the HA was performed either with or without CRR of the PV (n = 44). Clinicopathological variables and clinical outcomes were compared among the three groups. RESULTS: Although the VR-A group showed significantly more advanced disease than other groups, the R0 resection rate was comparable among the three groups (VR(-), 74 %; VR-PV, 80 %; VR-A, 80 %). The 5-year disease-specific survival rate was also comparable among the three groups (VR(-), 45.6 %; VR-PV, 51.2 %; VR-A, 22.3 %), but tended to be worse in the VR-A group than in the other groups. A similar trend was observed in morbidity rate. Lymph node metastasis was more frequent in the VR-A group (59 %) than in the other groups (VR(-), 33.8 %; VR-PV, 50 %). In the VR-A group, lymph node metastasis (p = 0.004) and adjuvant chemotherapy (p = 0.006) were determined to represent independent prognostic factors for survival according to multivariate analysis. CONCLUSION: CRR of the HA was considered efficacious in selected patients; however, long-term outcomes of the VR-A group seem unsatisfactory. Treatments additional to surgery may be necessary in cases requiring CRR of the HA.
