Bronchiectasis refers to the deformation and dilation of the bronchi due to chronic inflammation and fibrosis of the bronchi and surrounding lung tissue, which damages the muscles and elasticity of the bronchial walls. Clinically, this condition is known as bronchiectasis. The most typical symptoms include long-term coughing, coughing up large amounts of purulent sputum, and repeated instances of coughing up blood among others. Once bronchiectasis is diagnosed, it needs to be treated: First, we can clear the secretions from the bronchi, usually through nebulization to thin the mucus, and bronchoscopy or other local irrigation methods to clear the secretions inside. Second, after bronchiectasis occurs, we need to perform anti-inflammatory treatment for the bacteria infesting the bronchi, usually using sensitive antibiotics for treatment. Third, it is necessary to enhance the patient’s own immunity to prevent frequent recurrent infections. Fourth, if conservative treatment is not effective, surgical methods can be used to remove parts of the dilated bronchi, thereby achieving the treatment purpose.
