Research into the results of resection of hilar bile duct cancer.

We found mentions of 581 resections of hilar bile duct cancer in the literature to January 1989. Resection in 499 patients, reported or updated since 1980, resulted in an operative mortality of 12% and a 5-year survival rate of 13%. Resections confined to the hepatic duct confluence or extended to the quadrate lobe led to an 8% operative mortality and a 7% 5-year survival rate, although resections combined with major liver resection gave a 15% operative mortality and a 17% 5-year survival rate. Despite the best treatments available, present-day resection modalities are usually still not radical. Extension of resection in the retrohilar and hepatoduodenal direction might further improve the long-term surgical results.
