case_images: Lateral radiographic view of the cervical area. The nasogastric tube can be seen advanced up to the stricture site at approximately the second cervical vertebra.

case_images: Contrast medium and the nasogastric tube itself could be seen up to approximately 4 cm caudal to the larynx, where a narrowing of the esophageal lumen was visible at the second cervical vertebra (Figure 1).
case_images: Ultrasound image of the esophagus cranial to the esophageal stricture. Esophageal diameter is 9,5 mm. Left in the image is dorsal. C: carotid artery. E: esophagus. T: trachea (probe frequency 10 MHz, depth 2,5 cm).

case_images: Involvement of only the adventitia and tunica muscularis was suspected (Figures 2 and 3).
case_images: Ultrasound image of the stricture site. Left in the image is dorsal. A substantial decrease in diameter compared to being immediately cranial to the stricture can be observed. C: carotid artery. E: esophagus. T: trachea (probe frequency 10 MHz, depth 2,5 cm).

case_images: Involvement of only the adventitia and tunica muscularis was suspected (Figures 2 and 3).
case_images: Endoscopic view of the esophagus. The balloon catheter can be seen in place, fully dilated.

case_images: Subsequently a 240 cm long balloon catheter (CRE  PRO Wireguided, Boston Scientific) was placed into position by advancing it through the working canal of the endoscope (Figures 4 and 5).
case_images: Endoscopic view of the esophagus immediately after balloon dilation. Slight hemorrhage can be observed.

case_images: Subsequently a 240 cm long balloon catheter (CRE  PRO Wireguided, Boston Scientific) was placed into position by advancing it through the working canal of the endoscope (Figures 4 and 5). After deflation the stricture site was evaluated endoscopically and topically treated with 3 ml 2% dexamethasone to reduce possible swelling and scarring of the esophageal wall (Figure 5).
case_images: Ultrasound image of the stricture site at final follow-up examination. Diameter was measured at 10,9 mm. Left in the image is dorsal. C: carotid artery. E: esophagus. T: trachea (probe frequency 10 MHz, depth 3,5 cm).

case_images: The diameter at the stricture site had increased from 5 mm to 10,9 mm as assessed by ultrasonography (Figure 6).
