“…Esophagography has been found to have a sensitivity exceeding 95% for the detection of esophageal strictures (3,48,49). In the gastroenterology literature, some authors have argued that all radiographically diagnosed esophageal strictures should be evaluated with endoscopy and biopsy because of the difficulty of differentiating benign causes of luminal narrowing from malignant tumor on the basis of the radiographic findings alone (50 -53).…”

Benign esophageal strictures are a leading cause of dysphagia. Therefore, radiologists have an important role in detecting esophageal strictures and determining their cause. The most common cause of strictures in the distal esophagus is gastroesophageal reflux disease. Reflux-induced ("peptic") strictures may be associated with sacculations, fixed transverse folds, or esophageal intramural pseudodiverticula. In addition, scleroderma, nasogastric intubation, Zollinger-Ellison syndrome, and alkaline reflux esophagitis may be associated with stricture formation in the distal esophagus. Upper and midesophageal strictures may be caused by Barrett esophagus, mediastinal irradiation, ingestion of drugs or caustic substances, congenital esophageal stenosis, skin diseases, or esophageal intramural pseudodiverticulosis. Other unusual causes of esophageal stricture formation include Crohn disease, Candida esophagitis, graft-versus-host disease, eosinophilic esophagitis, Behçet disease, endoscopic sclerotherapy for esophageal varices, and glutaraldehyde contamination at endoscopy. Esophageal strictures are best evaluated with biphasic esophagography that includes both single- and double-contrast spot images. When esophageal strictures are detected at barium examination, the underlying cause can often be determined with a pattern approach that takes into account the clinical history, the appearance and location of the strictures, and the presence of other associated radiographic findings.

“…If significant mechanical narrowing is identified one may proceed with dilation at the same setting. Endoscopy is quite sensitive at detecting strictures less than 10 mm in diameter but slightly less sensitive for wider strictures (6). Endoscopy may not detect tapered narrowing of the esophagus when the lumen is wider than the endoscope and there is no associated mucosal abnormality.…”

Dysphagia may be defined as difficulty in swallowing. Dysphagia may be classified as oropharyngeal or esophageal; oropharyngeal dysphagia arises from a structural or functional abnormality in the oropharynx, and esophageal dysphagia occurs as a result of structural or functional abnormalities in the esophagus. Esophageal dysphagia may be further subclassified symptomatically as dysphagia for solids alone, which usually suggests a mechanical problem, versus dysphagia for liquids and solids, which is more suggestive of a neuromuscular problem. Dysphagia may be described by the patient as a sensation of food 'sticking' or as a sensation of food passing slowly through the esophagus. True dysphagia always indicates organic disease and always warrants investigation and consultation if no cause is found in initial studies. These symptoms should be distinguished from those of a persistent foreign body-type sensation or a sensation of a lump, which is more typical of globus sensation. Odynophagia, defined as pain with swallowing, may occur in association with esophageal dysmotility or as a result of mucosal disease in the esophagus.

Failure to perform an esophageal motility study-Esophageal manometry should be performed if no mechanical abnormality has been detected on esophagography and endoscopy.…”

Oropharyngeal and esophageal dysphagia involve different phases of swallowing, have different causes, and can usually be distinguished by a thorough patient history. Initial evaluation of patients with suspected oropharyngeal dysphagia includes patient history, physical and neurologic examination, and careful videofluoroscopic study of pharyngeal dynamics. Initial evaluation of patients with suspected esophageal dysphagia includes patient history and barium swallow with esophagography. Lesions such as Schatzki's ring or peptic stricture may not be detected unless the esophagus is sufficiently distended and the patient is given a bolus challenge.
