Before an EMR, you may be asked to not eat, or to drink only clear liquids. You may also need to clean out your colon as you would for a colonoscopy
. You may need to avoid smoking and/or taking certain medications before EGD. It’s an outpatient procedure, and you’ll be sedated with medication given through a needle in your arm (intravenously, or IV). Any discomfort is minimal.
Your doctor may numb your throat with a spray before placing the endoscope in your mouth. You’ll lie on your side during the procedure. Sometimes, the endoscope needs to be inserted through the rectum. Using a camera in the endoscope that sends pictures to a computer, your doctor guides the endoscope to the area of the lesion. Then the lesion is removed using tools inserted through the endoscope. Finally, the area where the lesion was removed is marked with ink so it can be easily found during future exams.
