title: [Endocavitary radiotherapy in an after-loading technic in malignant stenoses of the upper gastrointestinal tract and bile ducts].
abstract: Palliative brachytherapy with 192iridium in high dose rate technique was applied until August 1985 in 44 patients: 40 suffering from an inoperable malignant stenoses of the esophagus or cardia, and 4 from bile duct carcinomas located in the upper part of the duct. The patients with malignant stenoses of the upper gastrointestinal tract underwent laser therapy until an endoscope could be passed beyond this stenoses. Then an after-loading tube was placed endoscopically and the stenoses irradiated endocavitarily (7/Gray/session in 1 cm distance). In the patients with malignant bile duct obstruction a PTCD-catheter served to guide the iridium wire up to the stenotic region.
