Esophageal dilation is a procedure that allows your doctor to dilate, or stretch, a narrowed area of your esophagus [swallowing tube]. Doctors can use various techniques for this procedure. Your doctor might perform the procedure as part of a sedated endoscopy. Alternatively, your doctor might apply a local anesthetic spray to the back of your throat and then pass a weighted dilator through your mouth and into your esophagus.
