Thoracoscopy versus thoracotomy: indications and advantages.

Although the diagnosis and treatment of intrathoracic diseases have been affected by the use of thoracoscopy, the indications and advantages of this procedure are poorly defined. To review the indications and results in a community practice, 52 consecutive cases of thoracoscopy were reviewed and the postoperative courses were compared to a control group of 43 simultaneous thoracotomies. Operative indications for thoracoscopy included investigation or treatment of a lung mass (n = 33), spontaneous pneumothorax (n = 10), mediastinal mass (n = 4), pleural effusion (n = 2), mesothelioma (n = 2), and a ruptured hemidiaphragm (n = 1). General endotracheal anesthesia was used in each case. Overall, thoracoscopy was successful in 40 cases (77%). Conversion to formal thoracotomy was required in 14 cases (27%) secondary to poor visualization or to aid in further dissection. Compared to thoracotomy, complication rates were less (7.6 vs 16.2%), hospital stay shorter (5.5 vs 8 days), ICU stay shorter (0 vs 2 days) and pleural drainage time less (2 vs 5 days) in the thoracoscopy group. In summary, 73% of the patients in this study who formerly would have undergone thoracotomy were successfully managed with thoracoscopy alone, with acceptable morbidity and mortality. These data define the indications, morbidity, and mortality of thoracoscopy and suggest that thoracoscopy may emerge as the procedure of choice in the diagnosis and management of many thoracic diseases.
