[Video-assisted thoracoscopic surgery for diagnosis of pulmonary lesions].

23 patients (age 11-66 years) underwent video-assisted thoracoscopic biopsy for diffuse disease or peripheral nodular lesions of the lung. 12 had been previously treated for extrapulmonary malignancy and lung biopsy was done for suspicious metastases. In all cases except 1, lesions were identified and biopsied by thoracoscopy. The postoperative course was easier and shorter as compared to thoracotomy and the mean hospital stay was only 2.5 days. Thoracoscopic lung biopsy is a safe, effective and accurate diagnostic modality for diffuse lung disease and peripheral lesions. It is associated with minimal postoperative pain and discomfort, short hospital stay, early return to normal activity, and gives good cosmetic results.
