title: Video-assisted thoracic surgery--state of the art.
abstract: Video-assisted thoracic surgery (VATS) is one of the main medical revolutions of the past decade. For its satisfactory performance, the following prerequisites are essential: (1) knowledge and experience in thoracic surgery; (2) team of experienced anesthesiologists; (3) preoperative assessment of respiratory function; (4) adequate postoperative care; and (5) instruments specially designed for thoracoscopic surgery. VATS is routinely performed under general anesthesia with double lumen endotracheal intubation for separate control of each lung. Insufflation of carbon dioxide must not exceed 1-3 mm Hg. Too high pressure may cause harmful reduction of venous return and mediastinal shift with impairment of ventilation. Presence of adhesions should be determined by finger exploration of the pleural cavity. Operative ports should be placed carefully, avoiding damage to the intercostal nerves and vessels. The video technique can be used with efficiency for the following indications: pneumothorax, resection of pulmonary nodules, biopsies of lung, pleura and mediastinal structures, resection of mediastinal tumors, management of empyema, and hemostasis and closure of lacerations after trauma. Indications for esophageal procedures include esophagomyotomy for achalasia and resections of benign lesions. Repair of perforated esophagus is a matter of controversy, but in early stages it can be done thoracoscopically. Although video-pericardioscopy has been performed by some surgeons, this procedure can be done easier and faster using the direct approach without the video equipment. There are differences of opinion with regard to major pulmonary and esophageal resections for cancer. The apparent advantage of diminished pain is offset by inadequate resection, spread of malignant cells and potential damage to the resected specimen with loss of important information concerning pathology. Complications of VATS are few, and include prolonged air leak, dysrhythmia, respiratory failure, bleeding and infection. Due to progress over the past several years, VATS has become an inseparable part of thoracic surgery and should be included in the basic training of every thoracic surgeon.
