Radiotherapy of malignant obstructive jaundice

: Brachytherapy using the afterloading technique with iridium 192 and percutaneous irradiation using 16 MV photons are used for the irradiation of malignant obstructive jaundice. Mostly, however, a combination of both methods can be used to advantage. In bile duct tumors and Klatskin tumors, the endoluminal part can be treated using brachytherapy. The extralumenal growth and, if necessary, all affected regional lymph node areas can be treated by a 3D planned, percutaneous, moving field technique. Intraoperative radiotherapy can be used in a few cases as booster irradiation of tumor conglomerates at the porta hepatis. The decision to use irradiation must be made very carefully since solid tumors are usually involved that require a high target dose, the application of which can lead to unacceptable side effects. The radio-oncological spectrum is therefore confined predominantly to palliative therapy.
