Presentation
History of caustic ingestion about one month ago, followed by dysphagia and odynophagia.
Patient Data
A long-segment stricture with tapering is present in the mid-esophagus, typical for caustic ingestion stricture.
The visualized stomach and duodenum appear normal.
Case Discussion
This case demonstrates the typical fluoroscopic appearance of chronic corrosive esophageal stricture, including long-segment stricture with tapering margins.
Esophageal perforation and increased incidence of squamous cell carcinoma of the affected segment are the main complications.
It should be noted that barium contrast can be used in the chronic stage (after 21 days) of corrosive esophagitis, and often, there is a single long stricture with tapering involving the middle and lower esophagus. In acute and subacute stages, it's better to use a water-soluble contrast medium, and findings may include mucosal edema, ulceration and sloughing of the mucosa with esophageal dilatation and atony.
