    • Abstract

    Background
    The concept of“Guided Bronchoscopy”has been gradually notable because of the contribution to increasing the diagnostic yields for small peripheral pulmonary lesions (PPLs). Navigation systems such as electromagnetic navigation (EMN) and virtual bronchoscopic navigation (VBN) have been fundamental equipments for that concept. We have been consistently used this navigation software LungPoint (Broncus Technologies, Inc., Mountain View, CA) since it was gone on sale in Japan. We aimed to furthermore increase of diagnostic yields for small (≦30 mm) PPLs by diversified approach case by case in the basis of the LungPoint data using thin video-bronchoscope (P260F, 4-mm outer diameter; Olympus, Tokyo, Japan)

    Methods
    Between October 2010 and January 2013, a new combination diagnostic technique was all performed for the first time for the consecutive 132 patients (139 lesions) at our hospital. All of the patients had small PPLs with diameters of 30 mm or less as determined by chest computed tomography which were suspected of primary lung cancers. We used all of the data obtained from LungPoint system such as VB-image, navigating pathway and virtual fluoroscopic image to determine how to approach to the target bronchus into which the bronchoscope should be advanced. The other guided devices such as 20-MHz mechanical radial-type probe EBUS (RP-EBUS) and a guide sheath (GS) kit (Olympus, Tokyo, Japan) with an external diameter of 1.95 mm including forceps and brushing were used in combination case by case. Primary endpoints were overall diagnostic yield and diagnostic yield of malignancy.

    Results
    The variation of a combination use of multi-guided devices was VBN/VBN-EBUS/VBN-EBUS-GS. The number of lesion using each method was 34/47/58. The overall diagnostic yield of 132 cases (139 PPLs) was 74.8%. Diagnostic yield of malignancy was 66.7%.

    Conclusion
    A new combination of multi-guided devises technique via thin video-bronchoscope following the obtained data from LungPoint system was useful to determine what devices we should choice for approaching to the target and contribute to increasing the diagnostic yield for small (≦30 mm) peripheral pulmonary lesions.
