Abstract:
Results of surgical treatments for 57 patients who underwent resection for hepatic hilar bile duct cancer between 1984 and 1997 were studied. Bile duct resection was performed in eight patients, and combined resection of bile duct and liver was performed in 49 patients, of whom vascular reconstruction was added in 15 patients and pancreatoduodenectomy (PD) in six patients. All the operations of bile duct resection that were not combined with hepatectomy were non-curative. In the patients who underwent combined resection of the bile duct with liver, outcomes of the patients with well-differentiated adenocarcinoma were better than those with other lower-grade tumors. The factors related to the degree of tumor extension, such as serosal invasion, lymph node metastasis, lymphatic vessel invasion, perineural invasion, venous vessel invasion, and vascular involvement, were other factors which significantly influenced the survival. Curative resection yielded significantly better results than non-curative resection. Of all these variables, good tumor differentiation and vascular involvement were recognized as important prognostic factors by multivariate analysis. Most of the postoperative deaths were encountered in patients who underwent additional operations to hepatectomy, such as vascular reconstruction or PD. Improvement of surgical techniques and perioperative care has yielded better outcomes of vascular reconstruction. However, the application of hepatopancreatoduodenectomy should be limited due to poor outcomes of widespread bile duct cancer of which the histological grade is usually low. Whereas prognosis of bile duct cancer involving the hepatic hilus is mainly determined by the biologic characteristics of the tumor, surgeons should consider the fact that most patients die of local recurrence regardless of the biologic character of the tumor when curative resection is not performed.
