Bronchoscopy
Endoscopic Imaging of the Canine Airway
Bronchoscopy is an invaluable technique for the diagnosis of airway and lung disease in that it allows visual inspection of the trachea and major airways to assess for airway pathology, aids in the localisation and retrieval of airway foreign bodies, and allows accurate sampling from airways and lung areas of interest. In some disease situations bronchoscopy is a prerequisite for accurate definitive diagnosis. It is a routine procedure in the proper investigation of chronic respiratory problems, and is a standard technique in referral centres and beginning to be more commonly available in primary care practice.
The major difficulty most inexperienced operators will have using bronchoscopy is being able to recognise what is normal, and inexperienced operators often over-interpret bronchoscopic findings in order to fit the clinical presentation. However, it should be recognised that in many instances of both acute and chronic respiratory disease, no definite abnormality is identified. This is not necessarily a problem in that it allows the exclusion of certain diseases. The technique will not allow identification of conditions that are exclusively out with the airways, except if they impinge on the airways (mass lesions) or extend to communicate with the airways.

Bronchoscopy is a versatile tool used in various scenarios in veterinary medicine. Some of the common indications for its use include:
- Foreign Body Retrieval: Removal of objects inhaled or lodged in the airway.
- Diagnosis of Respiratory Diseases: Identifying conditions like chronic bronchitis, asthma, or pneumonia.
- Biopsy Collection: Taking tissue samples for histopathological examination in cases of suspected tumors or unexplained inflammation.
- Assessment of Airway Anomalies: Evaluating structural abnormalities like tracheal collapse or bronchomalacia.
- Chronic Cough Investigation: Determining the cause of persistent coughing unresponsive to standard treatments.
- Bleeding in the Respiratory Tract: Diagnosing and managing conditions causing hemoptysis (coughing up blood).
- Therapeutic Interventions: Administering medication directly to the airways or removing excessive mucus or fluids.
Bronchoscopy provides a less invasive alternative to traditional open-airway surgery and offers quicker recovery times. It’s crucial for pet owners to be aware of these applications to understand how bronchoscopy can be a vital tool in managing their pet’s respiratory health.
