This procedure is performed
when a person has the symptoms of trouble swallowing.
Often, the reason for the difficulty swallowing is a
narrowing of the esophagus. Dilation is usually done
at the time of an esophagogastroduodenoscopy (EGD) .
Dilation consists of passing long, tapered dilators down
the esophagus. Usually a small one first, then sequentially
larger ones are passed - one at a time. Dilation can also
be done with special balloon catheters. These are passed
right through the scope. It is a safe procedure when
performed by a physician with much experience.
