Evaluation of high-dose-rate intraluminal brachytherapy by percutaneous transhepatic biliary drainage in the palliative management of malignant biliary obstruction-A pilot study

This prospective pilot study demonstrated that PTBD followed by ILBT is a feasible procedure with good symptom control, definite impact on QOL, and minimal complications in such patients. A prospective randomized study is required to more accurately assess the benefit of ILBT compared with biliary drainage alone.
