Balloon Dilation Under Portable X-ray System in the Treatment of Pharyngo-oesphageal Strictures

"* All the esophageal dilation procedures will be performed using rigid hypopharyngoscope and / or oesophagoscope with endotracheal intubation under general anesthesia by experienced surgical and anesthesia team.~* The rigid hypopharyngoscope / oesophagoscope (Storz, germany) will be introduced through the mouth to whole through examination to localize the site of the stenosis then a contrast material will be injected via the endoscope and picture taken with X-DR portable x-ray system.~* After that a guide wire 0.035mm will be passed through the endoscope till the stomach. The guide wire site will be confirmed by with X-DR portable x-ray system and then a suitable size balloon catheter will be passed over the guide wire (Boston Scientific, Cork, Ireland), then the balloon catheter will be advanced through the stricture confirmed by taking a photo by the x-ray system.
