A bronchial stent is a cylindrical shaped hollow tube device that is placed in the airway of the patient to open the narrowed path and help him to breathe. Narrowed airways can result from lung cancer, infections, tuberculosis, metastatic cancer or other inflammatory diseases. This stent keeps the airway open and allows adequate airflow with normal passage of secretions. These airway stents can be temporary or permanent and are made up of materials such as metal and silicone or their combination.
Stents are deployed with help of bronchoscope that provides visuals with its attached camera. These can be customized as per airway and are unique in their own in their quality, shape, and sizes. A highly trained pulmonologist places the stents in the patient's airways. It does not involve any surgical incisions and the patients can be discharged the same day.
A number of indications for endoscopic treatment have been reported but the most frequent is lung cancer involving the airway proximal to the lobar orifices. In most patients with unresectable tumors only palliation is required.
- 1. Lung cancer
- 2. Primary airway tumors
- 3. Oesophageal cancer
- 4. Thyroid cancer
- 5. Head and Neck tumours
- 6. Metastases
- 7. Vascular compression
- 8. Inflammatory lesions
Stents can be a definitive treatment for patients with tracheal stenosis who are not candidates for surgery or used as a palliative measure in advanced malignancy to provide symptomatic relief, as was the case in our patient. Airway management in patients with tracheal stenosis undergoing stent insertion is challenging for the anaesthesiologist who has to ensure adequate ventilation in the presence of a stenotic segment, anaesthetic depth, suppress the stress response to insertion of the bronchoscope and has to provide a relatively still and dry field during stent insertion.
