EGD
UPPER GI ENDOSCOPY
Esophagogastroduodenoscopy
(EGD), also known as Upper Endoscopy, is a procedure that enables the
physician to perform a visual examination of the esophagus, stomach,
and duodenum (first part of the small intestine). A thin, flexible
instrument, known as an endoscope (or gastroscope), is introduced
through
the mouth and into the swallowing tube, or esophagus. This procedure is
used to identify the cause of swallowing difficulties, nausea,
vomiting, reflux, indigestion, abdominal pain, or chest pain.
Patients
should prepare for this procedure the day before coming in to the
facility. Please see our preparation instructions, also available on
this web site.
An
IV line is started and the patient is given pain medication and a mild
sedative to help them relax. In addition, the patient may receive a
topical anesthetic (numbing spray) in their throat to help prevent
gagging. The patient is positioned on their left side, and the
instrument is introduced through the mouth and into the esophagus,
stomach, and duodenum. Air is blown through the instrument into the
stomach to assist the physician in viewing the lining and other
structures. Because the instrument is very thin (about the thickness of
a finger), it does not interfere with normal breathing. Most patients
only experience minimal discomfort during the procedure, with the most
common side effect being a mild sore throat.
EGD
allows physicians to view abnormalities, like ulcers or tumors, which
do not show up well on x-rays. Other advantages include the ability to
remove small tissue samples (biopsies) or obtain some cells with a
small
brush (cytology), which can be sent to the laboratory for microscopic
evaluation. The endoscope can also be used to treat certain digestive
conditions, such as stretching areas of narrowing within the esophagus,
removing benign growths or polyps, and controlling gastrointestinal
bleeding.
The
EGD procedure usually takes about 20-30 minutes. When the test is
complete, the patient is allowed to recover until most of the
medication
has worn off. Because sedation is used, the patient is not allowed to
drive. Patients should bring a friend or a relative to drive them home.
Most patients can resume their normal diet and activities a few hours
after the procedure. If biopsies are taken, it may take 3-4 days to get
the results.
