There are a number of dilating techniques available to the physician. Simple bougie dilatation may be done in the office, in a sitting position, and with only an anesthetic spray of the throat. If endoscopy is performed at the same time, then it will be done in the endoscopy suite, usually under sedation. If X-ray fluoroscopy equipment is needed, the procedure is performed in the X-ray unit. Simple bougie dilatation may take only a few minutes. The other techniques require 20 to 30 minutes. Recovery is usually quick and the patient can soon begin eating and drinking to test the effectiveness of the treatment.
