Bronchiectasis refers to the inflammation and fibrosis of the bronchi and surrounding lung tissue due to various causes, ultimately leading to the destruction of the muscular and elastic tissue of the bronchial walls. This causes the bronchi to become deformed and permanently dilated, commonly referred to as bronchiectasis. The most common clinical symptoms of bronchiectasis include coughing, production of phlegm, and coughing up blood. When treating bronchiectasis, the first step is to treat the symptoms, such as administering treatments to reduce phlegm, fight infection, and stop bleeding. If the patient continues to experience symptoms repeatedly after these treatments, we may recommend surgical intervention, if the patient's condition allows, to remove the dilated bronchi, thereby achieving the goal of cure.
