Thoracoscopic wedge resection of peripheral lung lesions.
The increasing experience with minimally invasive surgery and advances in endoscopic equipment have expanded the role of thoracoscopy to include thoracoscopic pulmonary resections. In 11 patients we have evaluated the technical feasibility of thoracoscopic wedge resection of single peripheral lung lesions. In 8 patients the lesion could be exactly identified by thoracoscopy and be effectively resected using an automatic endoscopic stapler. All lesions were located within the outer third of the lung parenchyma with a maximum distance of 1.4 cm between lesion and visceral pleura. Mean diameter of the nodules was 1.9 cm and ranged from 1.0 to 4.1 cm. Histological analysis revealed completely excised tuberculomas in 4, carcinomas in 2, hamartoma in 1, and localised fibrosis in one patient. In 3 patients the thoracoscopic approach was unsuccessful because of difficulty in identifying the lesion or impossibility of achieving a reliable assessment of the intraparenchymal extension of the tumor. In conclusion, thoracoscopic wedge resection is helpful for the diagnostic and therapeutic management of peripheral lung lesions in carefully selected patients. Continued experience is necessary to be able to establish reliable criteria to assess which types of lung lesion can be excised safely and effectively by videothoracoscopy.
