Preliminary application of brachytherapy with double-strand I seeds and biliary drainage for malignant obstructive jaundice.

Aim: To evaluate the efficacy and safety of brachytherapy with double-strand I seeds and biliary drainage for malignant obstructive jaundice.

Methods And Materials: 42 patients with obstructive jaundice because of extrahepatic cholangiocarcinoma were enrolled. 22 patients (group A) received a biliary stent with common drainage tube implantation, and 20 patients (group B) received a biliary stent with double-strand I seeds radiotherapy drainage tube placement.

Novel brachytherapy drainage tube loaded with double I strands for hilar cholangiocarcinoma: A case report.

Background: Hilar cholangiocarcinoma (CC) is a common malignant tumor with high malignancy and poor prognosis. Most patients have lost the opportunity to undergo radical surgery when diagnosed. Although palliative drainage or biliary stent placement is a preferable choice, the tumor cannot be controlled.
