  • Title: The role of video-assisted thoracoscopic surgery in the diagnosis of the small peripheral pulmonary nodule.
    Author: Murasugi M, Onuki T, Ikeda T, Kanzaki M, Nitta S.
    Journal: Surg Endosc; 2001 Jul; 15(7):734-6. PubMed ID: 11591979.
    Abstract:
    BACKGROUND: The use of imaging techniques to detect small peripheral pulmonary nodules often results in a missed diagnosis. Thoracoscopy had limited application until recently, when advances in technology allowed thoracic surgeons greater visualization and mobility within the chest. METHODS: Between September 1992 and June 1997, 81 patients were treated for small peripheral pulmonary nodules by pulmonary wedge excision using video-assisted thoracoscopic techniques. The patients were 39 men and 42 women with an average age of 59.5 years. RESULTS: A definitive diagnosis was obtained in all cases. Malignancies were found in 44 patients (55%), which involved primary lung cancer in 28 patients and metastatic lesions in 16 patients. The rate of malignancy in nodules measuring 1 cm or less was 18%. There was no operative mortality or morbidity. CONCLUSIONS: We conclude that video-assisted thoracoscopic lung biopsy is a more effective and less invasive diagnostic tool for small peripheral pulmonary nodules.
