ReviewCT-directed diagnosis of peripheral lung lesions suspicious for cancer.
Small peripheral pulmonary nodules continue to be a diagnostic challenge and because of improved technology are also being identified with increased frequency. TNB, performed properly, is a highly accurate procedure and with careful attention to technical factors, nodules of any size in any location may undergo biopsy. A skilled cytologist is an essential part of the team. Continued advances in molecular diagnostics allow for an expanded role of the usefulness of this procedure.

ReviewVideo-assisted thoracic surgical applications in thoracic trauma.
VATS is a valuable and safe way to manage many problems in thoracic trauma. It may allow earlier diagnosis and treatment of posttraumatic complications of chest injuries with less morbidity. ⋯ The reduced pain and morbidity are attractive features compared with open thoracotomy. VATS continues to evolve in thoracic trauma, but unquestionably has proved value.

Flail chest is an uncommon consequence of blunt trauma. It usually occurs in the setting of a high-speed motor vehicle crash and can carry a high morbidity and mortality. The outcome of flail chest injury is a function of associated injuries. ⋯ There is no role for surgical stabilization for patients with severe pulmonary contusion. The underlying lung injury and respiratory failure preclude early ventilator weaning. Supportive therapy and pneumatic stabilization is the recommended approach for this patient subset.

ReviewPulmonary contusions and critical care management in thoracic trauma.
Many victims of thoracic trauma require ICU care and mechanical ventilatory support. Pressure and volume-limited modes assist in the prevention of ventilator-associated lung injury. Ventilator-associated pneumonia is a significant cause of posttraumatic morbidity and mortality. Minimizing ventilator days, secretion control, early nutritional support, and patient positioning are methods to reduce the risk of pneumonia.

Tracheobronchial injuries are relatively uncommon, often require a degree of clinical suspicion to make the diagnosis, and usually require immediate management. The primary initial goals are twofold: stabilize the airway and define the extent and location of injury. These are often facilitated by flexible bronchoscopy, in the hands of a surgeon capable of managing these injuries. ⋯ The mainstay of intraoperative management remains a single-lumen endotracheal tube. Most injuries can be repaired by simple techniques, using interrupted sutures, but some require complex reconstructive techniques. Follow-up to detect stenosis or anastomotic technique is important, as is attention to pulmonary toilet.
