AbstractLung biopsy remains an important investigation in the diagnosis of diffuse interstitial lung disease despite improved diagnostic yield of high resolution computed tomography scanning. We describe 19 pulmonary wedge biopsies (13 men and 6 women) performed using videothoracoscopic technique. The median age of the patients was 56 years (range 32-72 years). All our patients were suspected to have diffuse interstitial lung disease and were referred for lung biopsy to obtain a histological diagnosis. Thoracoscopic wedge excisions were accomplished under general anaesthesia using high frequency jet ventilation and a percutaneous stapling device. A tissue diagnosis was obtained in all patients: 8 had cryptogenic fibrosing alveolitis, 3 had interstitial pulmonary fibrosis, 2 had emphysema, 2 had extrinsic allergic alveolitis, 2 had sarcoidosis, 1 had non-specific chronic inflammation, and 1 had pulmonary haemosiderosis. There were no operative deaths. There was one failure resulting in conversion to an open procedure. There were three complications: two air leaks and one effusion. Median postoperative hospital stay was 2 days (range 2-7 days). We conclude that videothoracoscopic wedge biopsy is a safe and effective procedure and should be recommended in patients who require a histological diagnosis of diffuse interstitial lung disease.
