During the conventional diagnostic procedure, surgery known as mediastinoscopy is performed to provide access to the chest. A small incision is made in the neck just above the breastbone or next to the breastbone. Next, a thin scope, called a mediastinoscope, is inserted through the opening to provide access to the lungs and surrounding lymph nodes. Tissue or fluid is then collected via biopsy.
During an endobronchial ultrasound:
• The physician can perform needle aspiration on lymph nodes using a bronchoscope inserted through the mouth
• A special endoscope fitted with an ultrasound processor and a fine-gauge aspiration needle is guided through the patient’s trachea
• No incisions are necessary
