Endoscopic mucosal resection (EMR) is a minimally invasive procedure used to remove precancerous cells and tissues from the lining (mucosa) of the gastrointestinal tract. During the procedure, an advanced interventional gastroenterologist uses a long, flexible tube called an endoscope to suction, band, and remove any precancerous cells and tissues.
EMR is primarily used to remove small lesions or larger ones that have not reached the more inner layers of the gastrointestinal tract. The procedure is most often used to diagnose esophageal cancer and Barrett’s esophagus and may be used to diagnose colon cancer.
Preparing for an Endoscopic Mucosal Resection
Generally, you will be asked not to eat or drink anything for several hours before your EMR procedure. If you will be having a colon EMR, you will need to make sure your bowels are empty by taking laxatives or drinking a special solution, similar to how you would prepare for a colonoscopy.
You’ll receive clear, specific instructions from your doctor ahead of time, so you know exactly what to do to prepare for your EMR.
During the Procedure
EMRs are short procedures, lasting 30 to 60 minutes. During the procedure, your gastroenterologist will insert a thin, flexible, lighted tube called endoscope into your mouth or anus. The endoscope contains a small camera that sends real-time images to a monitor so your doctor can guide the endoscope to the specific area of the gastrointestinal tract to be evaluated.
If any unusual cells or tissues are observed, your gastroenterologist will use the thin wire on the end of the endoscope to lift and separate the tumor from the surrounding tissues and then use an electrical current in the wire to remove the tumor and seal the small cut it makes.
After the procedure, a pathologist will evaluate any tissue samples removed for signs of cancer or other abnormalities and share the results with your doctor.
Will There Be Side Effects Afterward?
If your EMR involves inserting the endoscope into your mouth and down into your esophagus, you may have a sore throat after your EMR. If your procedure involves inserting the endoscope into your anus to evaluate the large intestine or colon, you may feel some slight bloating, cramping, or gas pains immediately after EMR.
You may also experience some side effects from the anesthesia you receive such as nausea, vomiting, headache, and dizziness.
Your doctor will go over the possible side effects of EMR with you and answer any questions or concerns you may have about the procedure.
