Comparative study of self-expandable stent placement, bougie dilation, and balloon dilation for post-inflammatory oesophageal strictures

Figure 4 Fluoroscopically guided stenting procedure for the senile patient. A: A 20 mm × 120 mm oesophageal stent was introduced and inserted in the lower esophagus; B: The oesophagogram immediately after the procedure shows improved passage through the widened lumen of the lower esophagus; C: Restenosis was observed at the proximal end of the stent 2.5 months after stent placement; D: A second 20 mm × 100 mm oesophageal stent was implanted at the stricture site; E: The second stent migrated distally about 2 months after placement, leading to symptom recurrence; F: The two stents were successfully removed under fluoroscopy.
