Videoendoscopic procedures in thoracic surgery: technical aspects and report of removal of a mediastinal cyst.

Current videoendoscopic technology and percutaneous techniques of exposure and dissection have been successfully applied to abdominal surgery with favorable results. Application of this technology to our practice of thoracic surgery is the basis of this report. Video-assisted thoracic surgery was performed in 36 patients for the following indications: Raynaud's syndrome, undefined pulmonary nodule, persisting spontaneous pneumothorax, T1 bronchial carcinoma, and mediastinal cyst. Videoendoscopic surgical procedures were accomplished using double-lumen endotracheal anaesthesia and a percutaneous stapling device. Procedures performed using this technique include thoracic sympathectomy, wedge or keel excision, blebectomy, lung apex stapling, parietal pleurectomy, and dissection of the mediastinal cyst. Median operating time was 45 min (range, 15 to 90 min). Tissue diagnosis was obtained in all patients. Median diameter of excised nodules was 10 mm (range, 7 to 70 mm). There were no operative deaths. The single complication was a prolonged air leak. This new method of thoracic surgery appears to benefit the patients. For us it proved a secure way to perform thoracic surgery. Our case of removal of a benign cyst in the posterior mediastinum shows that video-assisted thoracic surgery has expanding applications in the field of general thoracic surgery.
