The Clinical Application of Bronchofiberoscope Examination on Pathogeny of Ateletasis

Objective To investigate the etiology of atelectasis with bronchoscopy.Methods 126 patients with CT diagnosed atelectasis were examined with bronchoscopy.Bronchial biopsy, bronchial brush, anti-acid stain was performed as necessary.Results Of all patients, 82(65%) of them were lung cancer, followed by chronic Inflammation 27(21.4%), tuberculosis(TB)14(11.1%),other causes3. The diagnostic rate with bronchoscopy for lung cancer, chronic inflammation,TB was 86.6%,96.3%,65% respectively. The main findings under bronchoscopy was tumor, infiltration and tissue shift with external push. The main case for atelectasis in middle to old age patients was malignant tumor (78.7%), inflammation(12.2%) and TB(7.1%);while in young patients, It was inflammation(53.5%), TB(25%) and tumor(17.8%).Conclusions The main causes for atelectasis were tumor , TB and inflammation. Bronchoscopy was useful in the etiology of atelectasis. Fine needle biopsy under CT or Bronchoscppy maybe a good method to improve the diagnosis.
