New 2 Micron Surgical Laser in Airway Disobliteration
The following information was presented at the 2005 European Respiratory Society Annual Congress by Franz Stanzel, Peter Raasch and Karl Haeussinger. Body: Airway recanalization in advanced cancers is one of the intervetional procedures of daily routine nowadays. Beside the Nd:YAG laser electrocoagulation and especially APC are widespread. Coagulation and hemostasis seem to be sometimes only suboptimal. A new 2 continuous wave DPSS laser (Revolix ) combines cutting and ablation advantages and achieves excellent hemostasis. We carried out a pilot sudy in 23 patients (15 male, 8 female) suffering from lung cancer (19), typical carcinoid (3), or lipoma (1) with central airway obstruction and retention pneumonia. All patients had total or subtotal obstruction of the trachea (5), main stem bronchi (15) or lobar bronchi (10). We used the Revolix for ablation of obstructing tumour masses in 35 bronchoscopies. The power setting was 5 - 15 W, pulsed or continuous, by flexible bare terminated or compressed air cooled fibres. In 20 out of 23 patients airway patency could be established. In 3 cases the stenosis was too long exceeding to the subsegmental level. Ablation was faster, h
