Abstract
Although transbronchoscopic microwave electrodes for respiratory tract tumor coagulation had some disadvantages, i.e., the breath-holding time was longer than with lasers and it took a longer time to achieve effects compared with lasers, there were also many advantages. We experienced less bleeding and smoke, a larger area could be coagulated in single procedure, and in addition to the immediate superficial effects, there is a tumor necrotising effect extending to the layer above the airway cartilage. In addition, coagulation at an angle of 90 degree to the long tudinal airway axis is possible. It is also very economical. This method was effective in treating airway stenosis and obstruction, especially in maintaining the airway prior to stent insertion.
