Bronchiectasis: Causes and management

Abstract

Bronchiectasis is a condition representing abnormal and permanent dilatation and distortion of medium sized bronchi, usually accompanied by destruction of the airway wall. Post inflammatory bronchiectasis remains very common in the developing countries as a sequel to pulmonary tuberculosis, whooping cough, and severe measles (among other causes). Cystic fibrosis is the most common cause of generalized bronchiectasis in developed countries. Symptoms primarily are chronic cough and expectoration of foul smelling sputum. Bronchography was, until recently, the investigation of choice for the diagnosis of bronchiectasis and the gold standard against which the current best imaging technique HRCT (high resolution computed tomography) has been compared. Treatment includes prompt attention to acute exacerbations, management of airway secretions and control of airway hyperreactivity. Treatment is aimed at the non progression of the disease and complete cure if possible. The role of surgical therapy has evolved from early curative resection for all patients to a more palliative approach. Patients with advanced generalized bronchiectasis should be considered for lung transplantation.
