Abstract
Endoscopy was compared in 90 patients with a radiographic diagnosis of peptic esophageal stricture. Retrospectively, 78 strictures were classified as valid diagnoses giving a positive radiographic predictive value of 87%. Endoscopy diagnosed 74 (95%) of the 78 peptic strictures, detecting all 45 strictures under 10 mm in caliber, but failing to detect four (12%) of 33 broader strictures. Nine (75%) of the 12 radiographic false-positive errors involved misinterpretation of muscular or mucosal rings of the lower esophagus. We conclude that endoscopy and radiology are equally effective and complementary methods for evaluating patients with suspected peptic stricture.
