High-dose rate intraluminal brachytherapy: An effective palliation for cholangiocarcinoma causing bile duct obstruction

- Intraluminal brachytherapy (ILBT) decreases the need for biliary drain changes.
- Post-ILBT, the median number of drain changes was 0 (range 0-4).
- Post ILBT, the 30-day and 60-day patency rates were 88% and 83% respectively.
- Most patients had a biochemical response; many had their bilirubin normalized.
