[Indication and outcome of extended right hemihepatectomy combined with pancreatoduodenectomy for bile duct carcinoma].

During the past 10 years, we have performed extended right hemihepatectomy combined with pancreatoduodenectomy (rtHPD) in eight patients with bile duct carcinoma. We compared the results in these patients with those in 43 bile duct carcinoma patients who underwent extrahepatic bile duct resection with more extensive hepatectomy than hemihepatectomy. Our indication for rtHPD is bile duct carcinoma of the diffuse type involving the intrapancreatic bile duct. For patients with obstructive jaundice, biliary drainage was performed preferentially in the part of the liver to be preserved. Portal vein embolization was performed before extended right hemihepatectomy or left trisectorectomy. Complete external drainage of pancreatic juice followed by second-stage pancreatojejunostomy was performed in five rtHPD patients. There were no hospital deaths or hepatic failures. There were four 5-year survivors after rtHPD. There was no significant difference between the cumulative 5-year survival rates after rtHPD (71%) and non-HPD (42%). Patients with bile duct carcinoma whose prognosis can be improved only by rtHPD exist and should be treated by rtHPD. However, considering the reported high mortality rate after this procedure, rtHPD should not be performed in an institution where its safety cannot be guaranteed.
