OBJECTIVES:Preliminary uncontrolled studies of photodynamic therapy (PDT) of bile duct cancer (BDC) have shown astonishingly good results in the reduction of cholestasis, improvement of life quality, and potential improvement of survival time. Therefore, we investigated the influence of PDT on survival time in advanced BDC in a randomized controlled(More)

Unfortunately, the existing dye laser systems are large and costly, and their maintenance is expensive. Therefore, we investigated(More)
