Abstract
BACKGROUND: There have been few specific reports on negative outcomes after video-assisted thoracic surgery. We report our combined experience from two centers in Asia. METHODS: From September 1992 to April 1995, 1,337 patients were operated on with the video-assisted thoracic surgical approach. All the patients were prospectively studied. RESULTS: There was one death (mortality rate, 0.07%) and 56 nonfatal complications: persistent air leaks (21), bleeding (6), wound infection (13), empyema (2), cerebrovascular accident (1), reexpansion pulmonary edema (2), deep vein thrombosis (1), prolonged ventilatory support (4), intercostal neuralgia (5), and port-site recurrence (1), giving rise to an overall nonfatal complication rate of 4.26%. Procedure failures consisted of 7 recurrences of spontaneous pneumothorax (of 407 cases or 1.7%); 2 recurrences of malignant pleural effusion (of 39 cases or 5.1%), and 2 local recurrences after resections for stage I lung cancers (of 41 cases or 4.9%). CONCLUSIONS: We conclude that video-assisted thoracic surgery is safe and effective for a wide range of procedures. A learning curve is present, and careful patient selection and attention to details are essential in optimizing surgical results.
