Thoracoscopic lung biopsy or open lung biopsy for interstitial lung disease.

ABSTRACT

Both traditional open lung biopsy through a limited thoracotomy and VATS lung biopsy are effective methods for obtaining parenchymal samples in patients who have respiratory insufficiency and radiographic pulmonary infiltrates. For patients with slowly progressive disease processes, who require an elective biopsy, VATS biopsy is the procedure of choice because of the ability to visualize and sample multiple areas of the lung, and because of the decreased postoperative pain. On the other hand, when patients are critically ill and already on high-level ventilatory support, the VATS method offers no advantages over the standard minimal thoracotomy.
