PURPOSE: The superDimension Bronchus System™ is a new device that allows guidance of endoscopic locations within the lung. This new technique of electromagnetic navigation has become available for diagnosing peripheral lung lesions without fluoroscopy. Aim of the study was to determine the learning curve.
METHODS: An experienced endoscopist was trained on this technique and subsequently procedure times and success rates were compared between the first 10 subjects to the second 10 subjects.
RESULTS: 20 patients (7 females, 13 males) were examined during a period of five months. There were no significant differences regarding solid tumor size (2.4 cm) as well as solid tumor location. The diagnostic yield (30 % vs. 70 %) and the navigation time (8,4 vs. 4,8 minutes) differed significantly (p<0.001). 1 case of pneumothorax requiring a chest tube was observed in the first group.
CONCLUSION: It was observed that already after 10 procedures the diagnostic yield was increased significantly and the navigation time was reduced significantly.
CLINICAL IMPLICATIONS: The superdimension Bronchus System™ is a promising new approach for diagnosing peripheral pulmonary lesions. Therefore the electromagnetic navigation technique can be attained in a relatively short period of time.
