Figure 17  A 26-yr-old male. A and B: Axial and sagittal computed tomography (CT) images showing long-segment esophageal stenosis related to caustic ingestion (orange arrows); C and D: With an initial upper endoscopy aborted, repeat upper endoscopy with the addition of fluoroscopic guidance allowed passage through a known stricture and eventual stent placement; E: Subsequent fluoroscopic upper gastrointestinal examination showing free contrast passage through the stented esophagus, with direct sagittal comparison to the initial CT in the sagittal plane.
