Intraluminal radiation therapy per endoprosthesis: A case study

Palliation of cholangeocarcinomas has been achieved by radiation delivered to the bile duct via endoprothesis. This case study supports and extends the works of others by describing the endoscopic techniques involved in the implantation of iridium seeds within a nasobiliary catheter. The case presented demonstrates endoscopic radiation treatment with no systemic radiation effects in a patient whose life extension was 19 months
