Surgery is generally not required for bronchiectasis, but may be considered in special cases. The treatment of bronchiectasis generally includes promoting sputum expulsion such as physical expectoration or mucolytic agents such as Ambroxol to promote sputum expulsion; actively controlling the infection with antibiotics such as levofloxacin in the acute phase; stopping hemoptysis such as Carbacillus in the presence of hemoptysis; and symptomatic supportive therapy such as bronchodilator such as long-acting anticholinergic drug tiotropium bromide in the presence of obstructive ventilatory dysfunction. If the presence of bronchiectasis is limited, after adequate internal medicine treatment is still stubborn to flare up, surgical resection of diseased lung tissue can be considered. If the bronchiectasis is complicated by hemorrhage and the hemorrhage comes from hyperplastic bronchial arteries, and the hemoptysis still recurs even after rest and antibiotic treatment, surgical treatment may be considered for those with limited lesions. Lung transplantation should be considered if appropriate in cases of disability despite all treatments. If a patient suspects or has developed bronchiectasis, he or she should go to the hospital for medical or surgical treatment under the supervision and advice of a physician.
