A nationwide questionnaire survey was conducted to investigate the indications, diagnostic yield, complications, outcome, and benefit of surgical lung biopsy for diffuse lung diseases. Surgical lung biopsies were performed in 410 patients at 132 institutes in 1998, 94% of them as video-assisted thoracoscopic surgery (VATS). Interstitial lung diseases of unknown etiology formed the largest diagnostic group, and consisted of 194 patients. The clinical diagnosis prior to lung biopsy was inconsistent with the final diagnosis in 32.8%. Complications were seen in 32 patients, and mortality was 1.2%. Acute exacerbation of the underlying disease was seen in 9 patients, four of whom died. Patients with nonspecific interstitial pneumonia and even usual interstitial pneumonia who were treated following biopsy showed better outcomes than those untreated. The physician in charge judged that 82.2% of the patients received clinical benefits from the biopsy procedure. We concluded that VATS lung biopsies are indicated in more cases to confirm diagnoses and as a reference for treatments in patients with diffuse lung disease.
