Thoracoscopy in Children: An Initial Experience with an Evolving Technique

Abstract

Recent technological innovations have improved our ability to perform thoracoscopy in children. Video imaging improves thoracoscopic visualization and enhances the role of the surgical assistant. The placement of multiple access ports improves the thoracoscopic manipulation of tissue. The laser permits the application of thermal energy to intrathoracic tissue for hemostasis without the risk of cardiac fibrillation. The endoscopic stapler allows hemostatic, airtight lung resection which obviates the need for routine tube thoracostomy. Our initial experience with these innovations applied to thoracoscopy was successful in 9 of 12 patients, ages 5 months to 17 years. For diagnostic cases, adequate tissue for histologic evaluation was always obtained. Complications of successful thoracoscopy included suspected air embolus on establishing the initial pneumothorax and persistent air leak requiring tube thoracostomy after resection of a bronchogenic cyst. There were no perioperative deaths. We performed biopsy of mediastinal masses or nodes, and lung, drainage of loculated pleural effusions, and excision of bronchogenic cysts. Thoracoscopy provides a safe, effective alternative to thoracotomy in children and will continue to be enhanced by improving technology.
