title: Application of the fold plication method for unilateral lung volume reduction in pulmonary emphysema.
abstract: BACKGROUND
  Unilateral lung volume reduction procedures are used to treat pulmonary emphysema. The most significant technical problem with this operation is an air leak from the pulmonary stump. Bovine pericardium has been used to prevent air leaks but is associated with interstitial pneumonia and a high cost.
  
  
  METHODS
  The fold plication method was devised to prevent postoperative air leaks to avoid interstitial pneumonia, and to decrease cost. This technique was applied in 20 consecutive patients with emphysema who underwent a unilateral lung volume reduction operation via a thoracoscopic two windows approach.
  
  
  RESULTS
  The operative time was approximately 1 hour. There was minimal postoperative bleeding, no persistent air leaks, and no evidence of pneumonia. Pulmonary function improved in all patients.
  
  
  CONCLUSIONS
  The unilateral fold plication method is an economical and safe alternative to bovine pericardial patching after lung volume reduction operation to prevent stump air leaks.
