title: Video-assisted thoracoscopic surgery in the diagnosis and treatment of chest diseases.
abstract: Video-assisted thoracoscopic surgery (VATS) has been used recently in the diagnosis and management of thoracic diseases. In this report, VATS experience with 95 cases, focusing on indications, surgical procedures, complications, and failure rates, are reviewed. Over the past 5 years, 95 VATS procedures for diagnostic and therapeutic purposes were performed in 59 men and 36 women. The specific indications for VATS were lung biopsy for undiagnosed diffuse lung disease (48), mediastinal biopsy (12) and cyst (2), pleural effusion (10), empyema (5), pneumothorax and bullous lung disease (6), pericardial effusion (2) and cyst (2), paravertebral abscess (2), solitary pulmonary nodules (3), and thoracic trauma (3). In all patients, postoperative pain was controlled with non-narcotic analgesics and was measured according to the visual analogue scale (VAS). There was no surgical mortality. Postoperative nonfatal complications were seen in seven cases (7.5%). The overall median duration of chest tube drainage was 2.7 days and the mean postoperative hospital stay was 3 days. For diffuse lung disease, a tissue diagnosis was obtained in all the cases. Definitive diagnosis in the patients with undiagnosed pleural effusion was obtained in 90% of cases, and the overall diagnostic rate was 98.5%. The success rate of the therapeutic procedures was 100% after a mean follow-up of 12 months (range, 6-30 months). Conversion to thoracotomy was needed in six cases (6.6%). All patients scored postoperative pain <50% according to the VAS. Video-assisted thoracoscopic surgery should be considered as a procedure of choice, with exceptional results in the following chest diseases: (a) undiagnosed pleural effusions; (b) recurrent, post-traumatic, or complicated spontaneous pneumothorax; (c) stage II empyema; (d) accurate staging of lung cancer; (e) emergency traumatic injuries of the chest; (f) peripheral solitary pulmonary nodule <3 cm; and (g) lung biopsy for pulmonary diffuse disease.
