Bronchiectasis is a chronic lung disease whose pathophysiology is poorly understood. It has traditionally been considered “permanent and irreversible”.1 In addition to chronic airway inflammation and infection, chronic aspiration has been implicated as another aetiological possibility.2-4
We recently cared for a Samoan child with cri du chat syndrome, admitted four times with wheezing before 15 months of age. He had persistent central and peripheral type wheezing and digital clubbing. A modified barium swallow revealed mild dysfunction of the oral phase of swallowing. A nuclear scintiscan revealed eight episodes of gastro-oesophageal reflux. Chest radiograph revealed bibasilar reticulonodular opacities with new right middle lobe disease (fig 1). High resolution computed tomography (HRCT) scan of his chest showed cylindrical bronchiectasis (fig 2). Bronchoscopy with bronchoalveolar lavage revealed inflammatory cells, and staining of the lavage fluid with oil red-O revealed numerous lipid laden macrophages, suggestive of aspiration.
He was designated “nil by mouth” and underwent Nissen fundoplication with gastrostomy tube placement. Seven months post-procedure, a follow up HRCT scan of his chest showed near resolution of the bronchiectasis (fig 3). By age 3.5 years the digital clubbing had resolved; a chest radiograph showed no bronchiectasis (fig4).
The term “bronchiectasis” has traditionally implied permanent, irreversible alteration in the anatomy of the airway.1 5Chronic aspiration is a recognised condition that can lead to bronchiectasis in adults and children.5 6 Bronchiectasis has also been shown to be more common in patients of Polynesian descent, as a result of a suspected ciliary defect.7 The resolution of the symptoms and the radiographic evidence of bronchiectasis in this child underscore the importance of aggressive therapy for aspiration and concomitant bronchial hyperreactivity, and the prudence of watchful waiting in stable paediatric patients with bronchiectasis prior to surgical intervention, because of the possibility of recovery.
