Abstract
when one considers how important eating is, one wonders why so little attention has been paid to the organ by which food is conveyed to the stomach.
Even if we don’t live to eat, as many people seems to, we must eat to live; hence the great importance of esophagus” this is the opening statm.ent of the monograph of Benedict and Nardi on the esophagus0 IL ‘nay be added that dysphagia or discomfort on swallowing which is th commonest symptom of esophageal diseases, interfers with the enjoyment of life more than is commonly realized. (William Body, 1970).
Dysphagia may be for fluid or solids, intermittent or progressive, percise or vague in its appreciation. It may be due to oropharyngeal or esophageal causes.
The former includes disorders of mouth, upper respiratory tract, and pharynx.
The different esophageal lesions which may cause dysphagia are classified into; congenital, foreign bodies impaction, benign stricture of the esophagus, spastic obstruction of the esophagus, benign and malignant tumours and obstruction from extrensic pressure.
Flouroscopy and cineradiography of the esophagus with swallowed contrast media are probably the important methods for evaluating dysphagia and diagnosing disordered esophageal motility (Alexender R. Margulis, 1970).
In this study we try to varify the role of radiological examination in the diagnosis of dysphagia end to survey the different sites and possible causes,cuad incidence of each in our ,ovcrnmewt.
This was confirmed by endoscopy, biopsy, and after operation.
