Electromagnetic navigational bronchoscopy-directed dye marking for locating pulmonary nodules.

Background: Small peripheral pulmonary nodules, which are usually deep-seated with no visual markers on the pleural surface, are often difficult to locate during surgery. At present, CT-guided percutaneous techniques are used to locate pulmonary nodules, but this method has many limitations. Thus, we aimed to evaluate the accuracy and feasibility of electromagnetic navigational bronchoscopy (ENB) with pleural dye to locate small peripheral pulmonary nodules before video-associated thoracic surgery (VATS).

[Non-real-time endobronchial bronchoscopy ultrasound assisted transbronchial lung biopsy in diagnosing peripheral pulmonary lesions].

Objective: To evaluate the role of non-real-time endobronchial bronchoscopy ultrasound(EBUS) assisted transbronchial lung biopsy (TBLB) in diagnosing peripheral pulmonary lesions (PPL).

Methods: One hundred and five patients [68 males and 37 females, mean age (59 ± 12) years, ranged from 39 - 81 years] with PPL confirmed by computered tomography (CT) were recruited in this study between June 1st 2011 and March 1st 2012. All cases received bronchoscopy examinations and presented with roughly normal results.

[Quantitative analysis of the ultrasonogram and histological findings in normal airway wall].

Objective: To find out the correlation between endobronchial ultrasonography (EBUS) images and histologic findings in normal bronchial wall via quantitative analysis of the airway wall thickness and the layer thickness.

Methods: From July 1st to December 31th in 2010, patients underwent lobectomy performed endobronchial ultrasonography (EBUS) before surgery and frost pathological examination after surgery. The layer thickness of EBUS and pathological images were measured.
