Bronchiectasis (bronchiectasis) is a deformation, distortion, until irreversible dilatation of the bronchial wall due to damage to the tissue structure, destruction, loss of normal elasticity, under the action of inflammation of the surrounding tissues, contraction of fibrous tissue and negative pressure pulling in the chest cavity. Chronic inflammation of the bronchi and surrounding lung tissues, resulting in damage to the bronchial walls and resulting in dilatation and distortion, is most often seen in children and young adults. Most are acquired and most have a history of childhood measles, pertussis, or bronchopneumonia. Bronchiectasis is often frequently treated with antibiotics, and bacterial resistance is very common. Pus sputum is diluted by expectorants and bronchodilators, then eliminated by postural drainage or fiberoptic bronchoscopic aspiration to reduce secondary infections and systemic toxicity. It can also be treated surgically. The most common complication after bronchiectomy is residual pulmonary atelectasis with pulmonary infection, which is treated with the exception of intravenous administration of effective antibiotics. The indications for surgical resection must meet the following conditions: 1. limited bronchiectasis confirmed by bronchogram or CT before surgery. 2, there is sufficient cardiopulmonary reserve to tolerate the resection prepared to be done. 3, There are irreversible manifestations that are not early curable conditions. 4, There is significant persistent chronic cough, recurrent or significant hemoptysis, and recurrent pneumonia attacks. 5, Failure of adequate drug therapy. If these conditions are met, the lung segment with dilatation can usually be completely resected with excellent surgical results.
