Validation of an endobronchial ultrasound simulator: differentiating operator skill level.

Simulator training for endobronchial ultrasound: a randomised controlled trial.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is very operator dependent and has a long learning curve. Simulation-based training might shorten the learning curve, and an assessment tool with solid validity evidence could ensure basic competency before unsupervised performance.A total of 16 respiratory physicians, without EBUS experience, were randomised to either...

Validation of a novel duplex ultrasound objective structured assessment of technical skills (DUOSATS) for arterial stenosis detection

INTRODUCTION Duplex ultrasound facilitates bedside diagnosis and hence timely patient care. Its uptake has been hampered by training and accreditation issues. We have developed an assessment tool for Duplex arterial stenosis measurement for both simulator and patient based training. METHODS A novel assessment tool: duplex ultrasound assessment of technical skills was developed. A modified dup...

Radial Probe Endobronchial Ultrasound for Peripheral Pulmonary Lesions: Initial Experience in an Indian Tertiary Healthcare Centre

Introduction : Diagnosis of peripheral pulmonary nodules is confusing; therefore, an accurate and safe lung biopsy can prevent unnecessary invasive diagnostic procedures. This study soughtto study the diagnostic yield, sensitivity, specificity, and negative and positive predictive values (NPV and PPV) of radial probe endobronchial ultrasound (EBUS)-guided biopsy for peripheral pulmonary lesions...

Differentiating benign from malignant mediastinal lymph node visible at endobronchial ultrasound (EBUS) using grey- scale textural analysis

A new middle-range diameter bronchoscope with large channel for transbronchial sampling of peripheral pulmonary lesions.

OBJECTIVE Although the diagnostic yield of guided bronchoscopy for peripheral pulmonary lesions has improved to 70%, it is still low compared with transthoracic needle aspiration. We produced a new bronchoscope with middle-range diameter and large channel (BF-Y0053, Olympus, Japan), and evaluated its diagnostic efficacy for peripheral pulmonary lesions. METHODS This was a retrospective study ...
