Esophageal dilation widens narrowed areas of the esophagus that can cause trouble swallowing. It’s often done during an upper endoscopy (EGD).
During endoscopy, your clinician gently stretches the narrowed area using a balloon or dilator. Many patients notice improved swallowing soon after. Some conditions may require repeat dilation over time.
This is typically done under sedation with monitoring. Complications are uncommon but can include bleeding, chest soreness, or perforation. Your team will review the expected benefits and risks ahead of time.
Esophageal dilation is usually performed as part of an upper endoscopy (EGD), so the prep is similar. Your stomach needs to be empty, which means stopping solid food and liquids for a set time before your procedure. You’ll receive written instructions about when to stop eating and drinking, and how to handle blood thinners, diabetes medicines, and other important medications.
On the day of the procedure, you’ll check in, review your health history, and have an IV started. In the procedure room, monitors will track your vital signs while you receive sedation and a numbing spray for your throat. The provider first performs an upper endoscopy to carefully examine the esophagus and stomach.
When the narrowed area is identified, a balloon or other dilator is guided into place and gently inflated or advanced to stretch the stricture. You shouldn’t feel pain during this step, though pressure or fullness is common. The scope and dilator are then removed, and you’re taken to recovery to wake up from sedation.
After esophageal dilation, you’ll stay in recovery for a short time while the sedative wears off. Your throat may be sore, and you may prefer soft or cool foods for the rest of the day. Your care team will review what was done, what to eat, and when to restart regular medications.
A responsible adult must drive you home, and you should not drive, drink alcohol, or make important decisions for the rest of the day. Call your provider or seek urgent care immediately if you develop chest pain, trouble breathing, fever, vomiting blood, or black, tarry stools, as these can be signs of a rare but serious complication.
