Hilar cholangiocarcinoma involving the portal vein bifurcation: long-term results after resection.
OBJECTIVE
Resection offers the only potential cure of hilar cholangiocarcinoma. Portal bifurcation involvement is often thought to contraindicate resection. We reviewed our experience with aggressive surgical management in 28 patients with hilar cholangiocarcinoma.


METHODS
All patients underwent hepatectomy and bile duct resection with hepaticojejunostomy. In 10 cases (group 1) the portal bifurcation was involved, necessitating portal resection and reconstruction; 18 (group 2) had no portal involvement. Frozen section of duct margins was routine. Survival was estimated using the Kaplan-Meier method and compared with the log-rank test.


RESULTS
Portal reconstruction in group 1 was by graft interposition (1), venoplasty using the posterior wall of the right portal vein (2), or end-end anastomosis (7). Hepatectomies included right trisegmentectomy (8), right lobectomy (4), and left lobectomy (16); 20 (71%) had concomitant caudate resection. Median survival was 18 months in group 1 and 32 months in group 2 ( P, not significant [NS]). One-, 3-, and 5-year survivals were 60%, 22%, and 22%, respectively, in group 1 and 70%, 47%, and 38%, respectively, in group 2 ( P= 0.319).


CONCLUSIONS
Portal involvement by hilar cholangiocarcinoma does not contraindicate resection.
