Recently, we have replied to many questions about bronchiectasis, and many patients have mentioned a question, whether to operate for bronchiectasis or not. First of all, let’s look at what is bronchiectasis: the definition of Baidu encyclopedia: bronchiectasis (bronchiectasis) is an abnormal, irreversible expansion and deformation of the proximal medium-sized bronchus due to the destruction of the muscular and elastic components of the wall, resulting in the formation of its lumen. In layman’s terms, the human lung is like a tree, and the tracheobronchial tubes are like the trunk and branches, which play a supporting role. Once the structure is destroyed, this piece of the lung will have problems. The most common is lung infection, coughing up pus and then is hemoptysis. The first depends on the extent of the lesion. Surgery works well for limited lesions, because after the problematic lung is cut out, what remains is a normal lung. Second: Bronchiectasis of both lungs can also be operated on, and only if the lesions are confined to one lung lobe, the surgery can be staged. Third: If the symptoms are mild and only a small amount of pus sputum is present, it can be controlled well with medication and can be observed. On the contrary, if there are repeated episodes of coughing up pus sputum, especially the hemoptysis, which can sometimes cause life-threatening hemoptysis, we should be alert. Early surgery should be performed.
