Description
Summary:Background and Objectives Swallowing disorders lead to chronic lung aspiration. Early detection and treatment of aspiration in children with dysphagia are important to prevent lung damage. Diagnosis of aspiration, which may be silent, requires an instrumental study such as fiberoptic endoscopic evaluation of swallowing (FEES). Despite its usefulness, it is rarely practiced by pediatric pulmonologists. This study aimed to evaluate the feasibility and utility of FEES performed in the pediatric respiratory unit of a tertiary hospital, analyze the clinical characteristics, endoscopic findings and proposed treatments, and identify the factors associated with penetration or aspiration. Methods Medical records of 373 children with suspected aspiration who were referred to the pediatric respiratory unit for FEES were reviewed retrospectively. Clinical characteristics, FEES findings, and the proposed treatments were analyzed. Results Laryngeal penetration/aspiration was seen in 47.9% of the patients. The most common associated conditions were neurological disease and prematurity. The most frequently observed endoscopic finding was altered laryngeal sensitivity (36.5%). Intervention was recommended in 54.2% of the patients. Complications were not seen during any of the procedures. The multivariate logistic regression model revealed an independent association between aspiration and alterations in laryngeal sensitivity (odds ratio [OR], 5.68), pharyngeal pooling (OR, 11.47), and post‐swallowing food residues (OR, 8.08). Conclusions The FEES procedure performed by pediatric pulmonologists is a reliable method for diagnosing aspiration in children. It can be safely executed by trained pulmonologists, and significant endoscopic signs other than aspiration can guide in the diagnosis and management recommendations.
