Endobronchial ultrasound bronchoscopy with needle biopsyMedical editor Arve Sundset MD
Oslo University Hospital
The location of the tumor or lymph nodes in the mediastinum determines whether an endoscopic ultrasound-guided fine-needle aspiration from the esophagus (EUS), or bronchus (EBUS-TBNA) is performed. EBUS of mediastinal lymph nodes is a minimally invasive procedure which allows the patient to avoid riskier procedures.
- Enlarged lymph nodes and/or tumor in the mediastinum
- To stage lung cancer or to confirm or disprove spread to the lymph nodes of the mediastinum
- To confirm or disprove suspicion of lung cancer or spread of other cancer in the mediastinum and to confirm the histological type
- Endoscope with accessories
- Puncture biopsy needle
- Equipment for preparation of cytological specimen
- The procedure is usually carried out under general anesthesia. In some cases, the procedure is performed with local anesthesia only.
- The patient should fast 8 hours before the procedure.
- The bronchoscope is inserted into the airways via an endotracheal tube.
- The appropriate lymph nodes are visualized by ultrasound.
- The aspiration needle is inserted through the work channel in the bronchoscope and guided by ultrasound, into the lymph node.
- Using back and forth motions with the needle, cells are aspirated from the lymph node.
- The material is prepared and assessed by a cytologist.
- The procedure can be repeated until representative material is obtained.
- The patient may return home the same day.
- The result from the needle biopsy is usually available after 2-3 days.
