    Abstract:
    UNLABELLED: The aim of this study was to define the normal manometric pattern of esophageal motility in response to food ingestion and to evaluate the contribution of esophageal manometry in the management of patients complaining of functional dysphagia. PATIENTS AND METHODS: Twenty-one healthy volunteers and 25 consecutive patients complaining of functional dysphagia with normal conventional esophageal manometry were included in this prospective study. An event marker was used to study the relationship between dysphagia and motility events. RESULTS: Twenty-two out of 25 patients (88%) reported dysphagia during esophageal manometry with food ingestion, while none complained of dysphagia during conventional esophageal manometry. Significantly, food ingestion induced in healthy volunteers and in patients: an increase in the amplitude and duration of esophageal body peristaltic contractions, and a decrease in their propagation speed; an increase in the basal pressure and a decrease in the relaxation percentage of the lower esophageal sphincter during deglutition. The percentage of solid swallows with one or several of the 7 abnormal motility patterns studied prospectively was significantly higher among patients (53.7%) than among healthy volunteers (4.3%) (P < 0.0001); it was also significantly higher among patients during swallows with dysphagia (70.1%) than without dysphagia (33.6%) (P < 0.0001). CONCLUSION: Esophageal manometry with food ingestion is an effective means of defining abnormal motility patterns and their relationship with dysphagia during functional dysphagia.
