Abstract
We compared radiology and endoscopy in 80 patients with peptic esophageal stricture, with special attention to radiographic sensitivity for stricture caliber. Each stricture was classified by length into three types: 1) short (6-25 mm in length); 2) annular (under 6 mm in length); and 3) long (over 25 mm in length). Overall, radiology detected 95% of all strictures, including 90% of those over 1 cm in caliber. Morphologically, 75% of all strictures were short; 14% annular, and 11% long. Radiographically, smooth-stricture margins reliably excluded active esophagitis, while irregularity correlated well with its presence. Properly performed, barium esophagram can accurately detect esophageal strictures with a sensitivity approximating that of endoscopy.
