EBUS with a radial probe is a new diagnostic modality, used in bronchoscopy, for evaluation of lung nodules/masses that are not directly visible with a flexible bronchoscope. By incorporating EBUS into standard bronchoscopy procedures, there has been a significant improvement in the diagnostic rates.
Department of Interventional Pulmonology at Max Hospital, Shalimar Bagh, New Delhi, has an experienced team performing Radial EBUS with a high success rate and is one of the very few centres in Delhi to have this facility.
When is it used?
Radial EBUS guided bronchoscopic lung biopsies are taken when a patient is detected with a peripheral lung nodule or a mass lesion.
How is radial EBUS performed?
Radial EBUS is performed under conscious sedation, just like normal flexible bronchoscopy.
A 360-degree rotating ultrasound probe is inserted through the working channel of the bronchoscope. The ultrasound images obtained are used to localize the abnormal lung nodule or mass lesion. Forceps biopsy is then taken with the simultaneous use of real-time X-rays to increase the diagnostic yield.
What are its advantages over other techniques?
The two most promising advantages of radial EBUS over CT guided transthoracic needle biopsy are:-
- Safety profile
- Minimal radiation exposure
Complications such as pneumothorax, intercostal tube insertion rates and bleeding are lowest among EBUS patients compared with the other modalities.
