PRESENT ROLE OF THORACOSCOPY IN THE DIAGNOSIS AND TREATMENT OF DISEASES OF THE CHEST

Since thoracoscopy was originally described in 1910, the application has been limited mainly to the diagnosis and treatment of pleural disease. Recent advancements in endoscopic equipment and refinement of surgical techniques have expanded the application of this procedure. Using video thoracoscopic techniques in 70 patients over the past 9 months, we have been able to perform a variety of procedures previously accomplished by "open" techniques. These procedures include (1) wedge resections of pulmonary nodules in 21 patients, using endoscopic mechanical stapling devices; (2) excision of the pericardium and drainage of the pericardial space in 6 patients; (3) dorsal thoracic sympathectomy in 6 patients; (4) apical blebectomy and pleurodesis in 6 patients; and (5) lung biopsies for diagnosis of diffuse lung disease in 5 patients. Additional procedures performed include biopsy of hilar masses (3), biopsy of esophageal mass, excision of a mediastinal cyst, and the drainage of a spinal abscess. The remaining 20 procedures were performed for the diagnosis and treatment of pleural disease. There was no mortality associated with the procedure and morbidity was lessened, compared with standard thoracotomy procedures. The postoperative hospital stay after elective procedures performed in well patients averaged 3 days and was often as short as 1 day. Our experience indicates a markedly expanded role for thoracoscopy in the diagnosis and treatment of thoracic diseases with less postoperative morbidity.
