Risk factors of morbidity and predictors of longterm survival after hepatopancreatoduodenectomy for biliary cancer

Background/Aims: Hepatopancreatoduodenectomy (HPD) is performed to achieve radical resection of malignant biliary tumors. We reviewed clinical outcomes to evaluate the utility of HPD in terms of morbidity and mortality. Methodology: A retrospective analysis was conducted on 17 patients underwent HPD between August 1991 and May 2013; 9 bile duct cancer, 5 advanced gallbladder and 3pancreatic tumor with liver metastasis. Results: The morbidity and mortality rates were 88.3% and 0%, respectively. Univariate analysis showed that a body mass index of ≥22 and preoperative total bilirubin level ≥0.8 mg/dl were significantly associated with severe complications. One, 3- and 5-year survival rate were 73.3%, 60.0% and 30.0%. In 14 patients with biliary carcinoma, univariate analysis showed that a histological grade of Gl was significantly associated with survival. Patients without pancreatic invasion or portal vein invasion tended to survive longer than patients with these types of invasion, although the difference was not significant. Conclusions: HPD can be performed with no mortality and provides a survival benefit for some patients with biliary carcinoma undergoing curative resection. In patients with grade Gl biliary carcinoma without pancreatic or portal vein invasion in particular, this aggressive surgery might offer a chance of long-term survival.
