Significance of fibreoptic bronchoscopy combined with percutaneous pneumocentesis in the diagnosis of peripheral pulmonary diseases / 解放军医学杂志

ABSTRACT

Objective To evaluate the significance of fibreoptic bronchoscopy combined with percutaneous pneumocentesis in the diagnosis of peripheral pulmonary lesions.Methods 269 patients with peripheral pulmonary diseases were diagnosed with fibreoptic bronchoscopy biopsy combined with bronchial brush biopsy.In 89 out of the 269 patients no positive findings were obtained,because the lesions were located in the lung hilum,medial sphere or mesosphere,when X-ray guided fibreoptic bronchoscopy biopsy combined with bronchial brush biopsy were employed.In 77 out of the 89 patients positive fingings were still lacking,as their lesions were located in the mesosphere or peripheralzone,when X-ray guided percutaneous pneumocentesis biopsy was used.In 70 out of the 77 patients,positive fingings were lacking,as their lesions were just beneath the chest wall,when B-ultrasonography guided percutaneous automatic elastic biopsy was employed.Results 276 times of fibreoptic bronchoscopy biopsy combined with bronchial brush biopsy were performed in 269 patients,final diagnosis was obtained in 82 of them,with a diagnostic rate of 30.5%;94 times of X-ray guided fibreoptic bronchoscopy biopsy combined with bronchial brush biopsy were performed in 89 patients,and final diagnosis was obtained in 66 patients,with a diagnostic rate of 74.2%;85 times of X-ray guided percutaneous pneumocentesis biopsy were performed in 77 patients,final diagnosis was obtained in 52,with a diagnostic rate of 67.5%;79 times of B-ultrasonography guided percutaneous automatic elastic biopsy were performed in 70 patients,final diagnosis was obtained in 49,with a diagnostic rate of 70.0%.A final diagnosis was made in a total of 249 patients,with a diagnostic rate of 92.6% when 4 methods were used in combination.Conclusion Combined use of fibreoptic bronchoscopy with percutaneous pneumocentesis biopsy may remarkably raise the diagnostic rate in the patients with peripheral pulmonary diseases,and is worth to be recommended for general use in clinical work.
