Videomanometry reveals clinically relevant parameters of swallowing in children

SummaryObjectiveThe aim of this pilot study is to demonstrate the technical and clinical feasibility of videomanometry to assess swallowing in infants and young children presenting with dysphagia.MethodsWe performed videomanometry using a combined solid state catheter and a perfused manometric sleeve assembly in eight patients (2–28 months) presenting at a tertiary care institution with symptoms of dysphagia. Solid state sensors were positioned at the inferior margin of the valleculae and the laryngeal entrance and the upper esophageal sphincter sleeve assembly was positioned across the upper esophageal sphincter. Manometric and radiological data were digitally recorded simultaneously using a manofluoromixer. Liquid bolus swallows were recorded in each patient and different geometric parameters of deglutition were measured.ResultsPlacement and fixation of the catheter was well tolerated and no adverse effects occurred. The children easily swallowed test boluses as selected during clinical examination. Results indicate that pharyngeal contractility can be evaluated as well as relaxation of the upper esophageal sphincter during swallowing of wet boluses.ConclusionsVideomanometry in young children is feasible with the limited discomfort of the placement of the catheter. It is a promising technique that will allow more accurate assessment of pediatric oropharyngeal dysphagia.
