Introduction Left-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. Methods A retrospective analysis of patients with PHC who presented between December 2009 and June 2015. Results Thirty-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). Conclusions Safe 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.

IntroductionObstructive jaundice as a result of bile duct tumour thrombus (BDTT) is an unusual clinical entity and an uncommon presenting feature of hepatocellular carcinoma (HCC). This study evaluates the outcome of hepatectomy for HCC with obstructive jaundice as a result of BDTT in non-cirrhotic livers.MethodsBetween 1997 and 2012, out of 426 patients with HCC in non-cirrhotic livers, 39 patients with BDTT (Group I n = 39), who underwent a hepatectomy, were analysed and compared with the non-BDTT group (Group II n = 387).ResultsThe demographic profile and biochemical parameters between Group I and Group II were compared; apart from the presence of jaundice at presentation and an elevated serum bilirubin, there were no significant differences. Post-operative morbidity and mortality were 11 (28.2%) and 2 (5.1%), respectively, in Group I. There were no differences between the groups with regards to the operative variables and short-term outcomes. The 1-, 3- and 5-year survival rates in Group I were 82%, 48% and 10%, respectively, with a median survival of 28.6 months and were significantly poorer than Group II (90%, 55% and 38%, respectively, with a median survival of 39.2 months).ConclusionThe mere presence of BDTT in HCC does not indicate an advanced or inoperable lesion. When technically feasible, a formal hepatic resection is the preferred first-line treatment option in these patients.
