    Abstract:
    BACKGROUND: Video-assisted thoracic surgery (VATS) is used for the diagnosis and treatment of some mediastinal lesions. However, large-size tumours are usually approached by thoracotomy or sternotomy. We report our experience of a full thoracoscopic approach for bulky intrathoracic lesions. METHODS: From November 2002 to March 2007, 14 patients with a bulky intrathoracic mass were referred for resection. The study group consisted of eight females and six males with a mean age of 44 years (range: 13-74). We defined as bulky a mass with a minimal cross-sectional diameter equal to or larger than 50 mm, as measured on the specimen by the pathologist. RESULTS: Thoracoscopic resection was completed in all patients. In 4 cases, the mass originated from the pleura, and in 10 cases from the mediastinum. The larger diameter of the lesion ranged from 50 mm to 160 mm, with a median of 90.2 mm. Operative time, calculated from insertion of the first trocar to skin closure, ranged from 40 to 190 min (mean: 102). Mean chest drain duration was 2.1 days (range: 1-4 days) and the mean hospital stay was 4.3 days (range: 3-11 days). There were no major postoperative complications. The final pathological diagnoses were the following: solitary fibrous tumours of the pleura (4), benign thymic cysts (2), teratomas (2), bronchogenic cyst (1), benign thymoma (1), pleuropericardial cyst (1) and benign neurogenic tumours (3). CONCLUSIONS: With experience and use of appropriate instrumentation, resection of bulky intrathoracic lesions by thoracoscopy is feasible and safe. It should be considered as a reliable alternate for tumours that are benign and most often asymptomatic.
