Dysphagia consists of various diseases, which all lead to an impaired
quality of life. Besides a thorough case history and clinical examinat
ion, there is a need for objective diagnostic examinations to evaluate
the extent of the disease. The present study includes 38 patients suf
fering from the most common causes of dysphagia such as benign or mali
gnant strictures of the esophagus, esophagitis, achalasia cardiae, cri
copharyngeal dysfunction and motility disorders. The patients were exa
mined by endoluminal ultrasonography using a 2.7 mm-wide-probe. The pr
esent study clearly indicates the value of the method in evaluating th
e extent of the disease in patients suffering from the aforementioned
diseases.
