title: Surgical biopsy: its appropriateness in diagnosing interstitial lung disease.
abstract: OBJECTIVE
  Our goal is to update advances in the use of surgical lung biopsy in the idiopathic interstitial pneumonias. We discuss an approach for identifying patients with idiopathic interstitial pneumonias who may benefit from surgical lung biopsy, newer surgical approaches and complications and risks of surgery.
  
  
  RESULTS
  A consensus statement on idiopathic interstitial pneumonias has described the natural history and response to therapy of idiopathic interstitial pneumonias. The statement discussed selection of patients with idiopathic interstitial pneumonias for surgical lung biopsy and avoidance of unneeded biopsy, particularly for patients with 'classical' radiographic findings of idiopathic pulmonary fibrosis. Video-assisted thoracoscopic lung biopsy continues to be the standard procedure for surgical lung biopsy. Newer approaches have used outpatient surgery for selected patients, earlier removal of chest tubes and modifications of surgical technique. At-risk patients include those with respiratory failure, rapid progression of disease, pulmonary hypertension and advanced disease.
  
  
  CONCLUSIONS
  Standard video-assisted thoracoscopic lung biopsy should be considered in patients with interstitial lung diseases of unknown cause who have a subacute course, ground-glass opacities on high-resolution computed tomography or features atypical for idiopathic pulmonary fibrosis, as these patients may respond to therapy. A step-wise process for selection of patients for surgical lung biopsy is recommended.
