Dysphagia.
Difficulty in swallowing may result from a motor disorder of the esophagus or an obstructing lesion. Dysphagia for liquids is characteristic of motor disorders, while symptoms on swallowing solid food point to mechanical obstruction. Difficulty initiating a swallow indicates oropharyngeal dysphagia, an abnormality of striated muscle. The major mechanical causes of dysphagia are peptic stricture, esophageal carcinoma and a mucosal ring.
