Placement of125I seed strands and stents for a type Ⅳ Klatskin tumor

Herein,we report a new technique that consists of placing two 125 I seed strands and two stents in the right and left intrahepatic bile ducts for the treatment of hilar cholangiocarcinoma.A 75-year-old man presented with jaundice and was diagnosed with Bismuth type Ⅳ Klatskin tumor.Abdominal computed tomography(CT) showed intrahepatic and extrahepatic bile ductdilatation and a soft tissue mass in the hepatic hilum.Because curative surgical resection was not possible,we placed 125 I seed strands and stents in the right and left intrahepatic bile ducts.Three months later,abdominal CT showed less intrahepatic and extrahepatic bile duct dilatation than before the procedure.This technique was feasible and could be considered for the treatment of patients with Bismuth type Ⅳ tumors.
