What is a bronchoscopy?
When is a bronchoscopy necessary?
Bronchoscopy is useful in investigating and analysing the presence of potential lung conditions:
- Nodules, masses, or infiltrates in the lungs
- Lung disease or lung cancer
- Infections such as pneumonia
Bronchoscopy can be useful in treating cancer, removing a foreign object, or cleaning out fluid or mucus from the airways.
When a cough persists despite conventional treatments, especially if it develops into wheezing, a bronchoscopy allows for a direct examination of the airways to identify potential irritants, infections, or structural abnormalities contributing to the chronic cough.
Individuals experiencing persistent and unexplained shortness of breath may require this procedure to investigate potential causes. This may include the assessment of airway constriction, blockages, or other respiratory issues affecting normal lung function.
Haemoptysis, is a concerning symptom that warrants immediate investigation. Bronchoscopy allows for a visual examination of the airways to identify the source of bleeding, such as tumours, infections, or vascular abnormalities.
For individuals with chronic respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD), bronchoscopy may be recommended to assess the severity of the condition, rule out other contributing factors, and tailor treatment strategies for optimal management.
For patients with lung cancer, an endobronchial ultrasound (EBUS), allows further exploration and biopsylymph nodes in the chest. This is often used to assess the extent of lung cancer and can aid in determining appropriate treatment. EBUS can be divided into two types:
Convex probe EBUS uses a slightly different bronchoscope which allows visualisation of structures beside the wall of large airways (such as abnormal mediastinal masses or lymph nodes seen on CT) and watching real time as a small needle is passed to biopsy (transbronchial needle aspiration: TBNA). This allows for targeted sampling whilst avoiding puncturing large blood vessels. Often a scientist is also in the room to provide feedback on the quality of the sample. This makes for a safe procedure with low rates of additional complications above and beyond standard bronchoscopy. EBUS TBNA may be used to provide staging information in suspected lung cancer, but many benign (not cancer) conditions are also responsible for such abnormalities on CT.
Radial probe EBUS (rEBUS) may be used to investigate shadows deeper within the lung tissue, beyond the reach of the tip of the bronchoscope. This refers to a thin rotating probe that can be passed through the working channel of a bronchoscope to provide ultrasound image further out in the lungs. This may use a standard or thin bronchoscope with a “guide sheath” (like a thin plastic straw to extend the working channel) or a specialised ultrathin scope which can travel more peripherally. Often a real time x-ray will be used to also confirm position, the probe is able to be removed and samples taken from the same location using a range of tools including forceps, a brush and needle. Complications depend on many factors, the risk of a collapsed lung (or pneumothorax) is low and less than for a CT guided biopsy and most bleeding that occurs is able to be easily stopped through the bronchoscope.
Results and Recovery
After your bronchoscopy, you will be carefully monitored for several hours. Initially, your mouth and throat may tingle with numbness for some time. Once the numbness subsides and you can swallow and cough normally, a gradual reintroduction of fluids will be recommended beginning with sips of water, followed by the inclusion of soft foods as your comfort allows.
Gargling warm water and introducing throat lozenges once the numbness has completely worn off can help alleviate discomfort.
The results of the procedure will be discussed with your doctor a few days afterwards. Some results may take longer depending if any special preparation (on tissue samples, for example) is required. The results are pivotal in determining the course of action for any identified lung issues or discussing further procedures if needed.
