Abstract

OBJECTIVES: High-resolution impedance manometry (HRIM) enables biomechanical swallow assessment. Piecemeal deglutition (PD) defines swallowing of a single bolus in 2 or more portions. We investigated PD sequences on HRIM recordings to ascertain appropriate swallow selection for analysis and to determine the impact of PD on swallow function measures. METHODS: Pharyngo-esophageal motility and bolus flow were assessed in 27 children (19 M, mean age 15 months) with repaired esophageal atresia and trachea-esophageal fistula, but who were asymptomatic of oropharyngeal dysphagia. A consistent volume of between 2 and 5 mL saline boluses was given to each patient. Retrospectively, PD sequences were d..
