IntroductionLeft-sided liver resection (LLR) for perihilar cholangiocarcinoma (PHC) may require right hepatic artery (RHA) resection and reconstruction because of its intimate relationship with the biliary confluence. Consequently right-sided resections (RLR) are preferred for Bismuth-Corlette IIIb tumours, and resections avoided in Bismuth-Corlette IV tumours with left lobar atrophy when the RHA is involved by tumour.MethodsA retrospective analysis of patients with PHC who presented between December 2009 and June 2015.ResultsThirty-six patients underwent resection for PHC (23 LLR, 13 RLR). The number of Bismuth-Corlette IV patients undergoing LLR was significantly greater than those undergoing RLR (8/23 vs 0/13, p = 0.032). The need for arterial reconstruction (AR) was significantly greater during LLR than RLR (10/23 vs 0/13, p = 0.006). Postoperative liver dysfunction was greater after RLR (5/13 vs 0/23, p = 0.003), and hospital stay was shorter after LLR (10 vs 15 days, p = 0.013).ConclusionsSafe AR increases the ability to perform potentially curative LLR for PHC. This improves the resectability rate for PHC, particularly for Bismuth-Corlette Type IV tumours. The larger liver remnant after LLR results in less postoperative liver dysfunction and shorter hospital stay without increased operating time, blood loss or morbidity.
