Liver Resection for Type IV Perihilar Cholangiocarcinoma: Left or Right Trisectionectomy?

Résumé

How the side of an extended liver resection impacts the postoperative prognosis of advanced perihilar cholangiocarcinoma (PHC) is still controversial. We compared the outcomes of right (RTS) and left trisectionectomies (LTS) in Bismuth-Corlette (BC) type IV PHC resection. All patients undergoing RTS or LTS for BC type IV PHC in a single tertiary center between January 2012 and December 2019 were compared retrospectively. The endpoints were perioperative outcomes, long-term overall (OS), and disease-free survival (DFS). Among 67 hepatic resections for BC type IV PHC, 25 (37.3%) were LTS and 42 (63.7%) were RTS. Portal vein and artery resection rates were 40% and 52.4% ( = 0.29), and 24% and 0% ( < 0.001) in the LTS and RTS groups, respectively. The severe complication (Clavien-Dindo > IIIa) rate was comparable (36% vs. 21.5%, = 0.357) while the postoperative liver failure (POLF) rate was lower in the LTS group (16% vs. 38%, = 0.048). The R0 resection rate was similar between groups (81% vs. 92%; = 0.154). The five-year OS rate was higher in the LTS group (66% vs. 30%, = 0.009) while DFS was comparable (43% vs. 18%, = 0.11). Based on multivariable analysis, the side of the trisectionectomy was an independent predictor of OS. Compared with RTS, LTS is associated with lower POLF and higher overall survival despite more frequent arterial reconstructions in type IV PHC. Although technically more demanding, LTS may be preferred in the treatment of advanced PHC.
