  • Title: Diagnostic imaging in the evaluation of dysphagia.
    Author: Barloon TJ, Bergus GR, Lu CC.
    Journal: Am Fam Physician; 1996 Feb 01; 53(2):535-46. PubMed ID: 8629536.
    Abstract:
    Evaluation of dysphagia is a challenge commonly encountered by family physicians. Dysphagia may be classified as either the oropharngeal type or the esophageal type and may have a variety of etiologies. Possible causes of oropharyngeal dysphagia include Zenker's diverticulum, pharyngeal carcinoma, pharyngeal webs and strictures, lateral pharyngeal pouches and neuromuscular diseases. Esophageal dysphagia can be caused by esophageal carcinoma, esophageal stricture and webs, achalasia, diffuse esophageal spasm and scleroderma, caustic esophagitis and infectious esophagitis. Studies using different textures of barium allow evaluation of the swallowing mechanism. Static images are obtained to evaluate the integrity of the mucosa.
