Radiological assessment of dysphagia with endoscopic correlation

Four hundred fifty consecutive patients with dysphagia were evaluated radiologically over a 14-month period; 127 of these (28.2%) were also examined endoscopically. The most common abnormality seen was dysmotility (34%), followed by hiatal hernia, benign stricture, and esophagitis. Correlation with endoscopy was generally good. Radiologic study demonstrated all cases of esophageal malignancy; radiologic/endoscopic correlation was also strong in patients with moderate or severe esophagitis, though the radiologist had some difficulty detecting mild inflammation. Endoscopy failed to demonstrate some benign strictures. Radiologic study was relatively accurate in detecting significant organic disease; most motility disorders were not detected by endoscopy. For these reasons, as well as lower cost, increased convenience, and patient comfort, radiologic assessment is recommended as the primary method of evaluating patients with dysphagia.
