Abstrakt: Background: Perihilar cholangiocarcinoma (pCCA) is a highly lethal hepatobiliary cancer. Radical resection offers the best chance for extended survival, but the efficacy of left-sided hepatectomy (LH) versus right-sided hepatectomy (RH) remains controversial.
Methods: A systematic review and meta-analysis of non-randomized cohort studies comparing LH and RH in patients with resectable pCCA was conducted. Subanalyses were performed based on year of publication, region, number of cases and Bismuth classification (BC) ≥ III.
Results: Nineteen studies involving 3838 patients were included, with 1779 (46 %) undergoing LH and 2059 (54 %) undergoing RH. LH was associated with increased overall survival (OS) in subgroup analysis of studies reporting hazard ratios (HR) (logHR 0.59; p = 0.04). LH showed higher rates of arterial resection (14 % vs. 1 %), transfusion (51 % vs. 41 %), operation time (MD 31.44 min), and bile leakage (21 % vs. 18 %), but lower rates of post-hepatectomy liver failure (9 % vs. 21 %) and 90-day mortality (8 % vs 16 %). Three-year disease-free survival rates increased in Western centers but decreased in Eastern centers.
Conclusion: LH is linked to higher OS in this analysis but is a more demanding technique. Resection side decision should consider several factors, including future liver remnant, tumor location, vascular involvement, and surgical expertise.
