Solid swallowing versus water swallowing: manometric study of dysphagia

Abstract
The aim of the study was to investigate whether a soft solid bolus can induce abnormal manometric patterns in patients with dysphagia and normal standard manometry. The study group comprised 12 normal volunteers and 22 patients with dysphagia. Manometry was performed using 10 wet swallows followed by 10 swallows of marshmallow. The results show: (1) in normal subjects the mean contraction amplitude is significantly greater (PPP<0.0001). We conclude that soft solid swallowing is useful in the study of patients with dysphagia.
