Bronchofibroscopy for elderly patients with hemoptysis of unknown reason

The results of bronchofibroscopic examinations in 78 elderly patients with hemoptysis were reported in the present study. Pathogerutic diagnosis was obtained by bronchoscopy in 91%(71/78) of the patients. Lung cancer had been found to be the primary cause of the hemoptysis in this studied group, which accounted for 48(61.8%) cases. Other causes leading to hemoptysis included bronchiectasis in 12(15.3%) patients and pneumonia in 11(14.1%) patients, but the morbidity of tuberculosis (6.4%) was relatively low in the present group. Among 41 patients with lung cancer, 30 of them had squamous cell carcinoma. Small cell carcinoma was rare, which was found in 5 patients only. Diffuse infiltrate shadows and pulmonary atelectasis on the chest roentgenogram were common in carcinomia patients, which presented in 46.3% and 61% of the patients, respectively. The clinical manifestations of the cancer were bloody spatum, faver, chest pain and marasmus. Pulmonary malignency should be considered in the elderly if hemoptysis. Occurred in combination with the abovementioned symptoms. Furthermore, bronchofibroscopy was indicated and should be carry out in time.
