Infants without apparent risk factors with aspiration as a cause of respiratory symptoms - a retrospective study.

Abstract

Dysphagia is common in children born prematurely or those with neuromuscular conditions or airway malformations. Few studies have reported on children with isolated dysphagia and there is significant variation in the literature regarding clinical outcomes. The aim of this study was to characterise the clinical presentation of children with isolated dysphagia as well as the diagnostic evaluation, treatment strategies and clinical outcomes. A retrospective chart review was conducted of children with isolated dysphagia presenting to a tertiary paediatric centre over a 10-year period. We describe these patients' presentation, clinical feeding assessment findings, radiological findings, treatment strategies and outcomes. Seventeen children were identified. Recurrent respiratory tract infections were the most common presentation (82%). Oral feeds were continued in 9 (53%) with the remaining being NG fed. Gastrostomy tubes were required for long-term nutrition in 6/8 (75%) of these cases. At follow-up, 11/17 (65%) had resolution of symptoms and are on full oral feeds. The mean age at resolution is 3.45years. Of those who required gastrostomy 50% have had them removed. Isolated dysphagia should be considered in children presenting with recurrent, otherwise unexplained respiratory symptoms. Resolution can take a number of years.
