title: [Open lung biopsy in diagnosis of interstitial lung disease].
abstract: OBJECTIVE
  To evaluate the role of open lung biopsy in diagnosis of interstitial lung disease.
  
  
  METHODS
  24 patients with interstitial lung disease who underwent open lung biopsy from 1993 to June 1998 were reviewed.
  
  
  RESULTS
  The documented pathologic diagnosis in 24 patients with interstitial lung disease who underwent open lung biopsies were: 7 IPF (UIP), 1 acute interstitial pneumonia (AIP), 3 BOOP, 2 DPB, 3 sarcoidosis, 2 tuberculosis, 1 histiocytosis-X and 1 lung cancer. Most of these patients did not definitely diagnosed through their clinical evaluation including history, chest X-ray, pulmonary function tests and TBLB.
