EBUS-TBNA is performed either in an endoscopy suite or an operating room. A recent CT scan of the chest is required for the operator to review before and during the procedure. The average procedure time varies from 20 to 40 minutes.
Anaesthesia
EBUS-TBNA is performed either with sedation or under general anesthesia. The EBUS TBNA scope is passed orally (sometimes nasally) or via laryngeal mask or via an endotracheal tube or a rigid bronchoscope. Your doctor will discuss with you about technique.
Technique
Once the target lymph node or mass has been clearly identified with EBUS, the needle is inserted under real-time ultrasound guidance. The specimens are then collected and sent to the laboratory. Samples may be sent for cytology, histology and microbiology or other studies which is determined case to basis on.
