endobronchial ultrasonography

Abbreviation: EBUS
The fitting of a bronchoscope with an ultrasound transducer to identify masses adjacent to the bronchi. EBUS has been used to improve the diagnostic yield of transbronchial lung biopsies and needle aspiration in patients suspected of having lung cancer and sarcoidosis.

Although complication from mediastinoscopy are rare they may be catastrophic and include vocal cord paralysis, innominate vein damage and even death17, EBUS TBNA on the other hand is generally a safe procedure.
Both groups were compared with respect to time taken for insertion, manipulation, ease of insertion, attempts at insertion, movement during EBUS and procedure, maintenance of airway, laryngopharyngeal morbidity, post-procedure discomfort, cough, fibreoptic assessment of vocal cords, airway sealing pressure and other complications.
The eBus programme is being implemented under the Climate Change Commission as well as the Department of Energy.
After assessment with regular bronchoscopy, EBUS was performed if there remained LNs that were either negative for malignancy by C-TBNA or not sampled with C-TBNA due to anatomical location that, if positive for malignancy, would impact staging.
Radial EBUS has a 20-MHz (12e30 MHz available) rotating transducer that can be inserted together with or without a guide sheath through the working channel (2.0-2.8 mm) of a standard flexible bronchoscope.
A convex probe EBUS (BF-UC180F, Olympus, Tokyo, Japan) was used to examine the lymph nodes, and the ultrasound images were processed with a dedicated scanner (EU-ME1, Olympus, Tokyo, Japan).
In all patients, the mass was able to be identified using EBUS in 97.2% (70/72), and 91.7% (66/72) had a final diagnosis, 56 patients had malignancies, ten patients had benign diseases [Table 1].
Endobronchial ultrasound (EBUS) elastography is a novel technique for measuring tissue stiffness during EBUS-guided transbronchial needle aspiration (EBUS-TBNA).
