One hundred twenty four Nd:YAG laser procedures were performed on 79 patients (age range, 25 to 89 years) over a five-year period at our institution. Over 90 percent of patients had malignant tumors. The fiberoptic bronchoscope (FOB group) was used exclusively during the first two years (61 cases, 32 patients). All except four of these cases utilized conscious sedation and local anesthesia. Subsequent to this, the rigid bronchoscope (RB group) was used as the primary instrument under general anesthesia (51 cases, 42 patients). Twelve cases combined both bronchoscopic modalities (combined group, 12 patients). The percentage improvement in proximal airway lumen diameter post-Nd:YAG laser therapy was significantly greater using the RB (p less than 0.05). For distal lesions, the FOB was superior (p less than 0.05). There was no difference in the complication or survival rates between the groups. Our data suggest that whenever possible, the RB should be used to treat proximal lesions, and the FOB should be used for distal lesions. Both bronchoscopes are often used together. Hence, laser bronchoscopists should be proficient in both bronchoscopic techniques.
