Bronchiectasis is an irreversible dilation of the bronchial tree causing chronic respiratory symptoms. It results from local infection/inflammation and inadequate clearance of secretions. Key clinical features include chronic productive cough with sputum, dyspnea, and clubbing. Diagnosis involves chest X-ray and high-resolution CT scan. Management focuses on reducing exacerbations to less than 2 per year through smoking cessation, chest physiotherapy, vaccinations, bronchodilators, mucoactive agents, and long-term antibiotic therapy based on sputum cultures. Surgical resection or lung transplant may be considered for severe cases.
