Photodynamic therapy for palliation of nonresectable bile duct cancer—preliminary results with a new diode laser system

Abstract

PDT with the diode laser system seems to be effective in reducing malignant bile duct stenosis. This treatment is minimally invasive and has a low specific complication rate. Randomized, controlled studies comparing PDT with the insertion of endoprostheses and long term follow-up of results are needed to confirm the promising short term results.
