Electromagnetic Navigation Bronchoscopy-Guided Dye Marking for Thoracoscopic Resection of Pulmonary Nodules.
Annals of Thoracic Surgery 2016 July
BACKGROUND: Computed tomography scans are increasingly used not only for lung cancer screening but also for staging and evaluation of other cancers. As a result, more patients with pulmonary nodules, many with subcentimeter lesions, are being referred to thoracic surgeons, some with concern for primary lung neoplasm and others with possible metastatic lung lesions. Obtaining a definitive diagnosis of these lesions is difficult. Electromagnetic navigational bronchoscopy (ENB)-guided pleural dye marking followed by thoracoscopic resection is a novel alternative technique for definitive diagnosis. The main objective of this study was to evaluate the feasibility and our initial experience with ENB-guided dye localization and minimally invasive resection for diagnosis of lung lesions.
METHODS: Selected patients with lung lesions underwent ENB-guided dye marking and minimally invasive resection. The primary end points were the rate of nodule localization and definitive diagnosis of the nodule.
RESULTS: We performed ENB-guided localization and minimally invasive resection in 29 patients. The median lesion size was 10 mm, with a median distance from pleural surface of 13 mm. The operative mortality was 0%. The median hospital stay was 3 days. The nodule was localized and resected, and a definitive diagnosis was obtained in all patients (29 of 29; 100%). The nodule was neoplastic in 19 patients. All malignant lesions were completely resected with negative microscopic margins.
CONCLUSIONS: Our initial experience with ENB-guided dye localization and minimally invasive resection found that the technique was feasible, safe, and successful in the diagnosis of small lung lesions. Thoracic surgeons should further investigate this method and incorporate it into their armamentarium.
