Oesophageal Dilatation is performed during panendoscopy to open up a stricture (narrowing) of the oesophagus.
During panendoscopy, a fine guiding wire is passed through the endoscope down the oesophagus and through the blockage. The endoscope is slightly pulled back to allow the dilating tube to be inserted next to the blockage. The dilator then slides along the guiding wire allowing the clinician to expand the blocked oesophagus.
This procedure is performed while the patient is sedated, resulting in little if any discomfort for the patient.
