Endoscopic Mucosal Resection
Endoscopic mucosal resection (EMR) is a technique used to remove abnormal tissue, polyps and growths from the digestive tract. Successful EMR procedures often eliminate the need for surgery. EMR involves passage of the endoscope toward the affected area. Then, a device at the end of the endoscope allows removal of the abnormal tissue with cautery techniques. This tissue is then sent for pathology analysis. This technique can remove many lesions that previously required surgery to address.
What to Expect
When you arrive, the nurses will review your medical records and medications, your vitals will be taken and an IV will be started so sedatives can be administered. Once you’ve been sedated, the doctor will place an endoscope through either your mouth or anus, depending on where the abnormal tissue is located. The high-definition endoscope will send the images to a screen. If there is a tumor, the endoscope will be used to apply suction to the tumor to lift it up and away from surrounding tissues. Then, a thin wire will be fed through the endoscope and placed around the base of the tumor. The tumor will be cut using an electrical current sent through the wire. It will seal the cut simultaneously. The tumor will then be suctioned out, removed through the endoscope and sent for pathology analysis. You will be monitored in a recovery room until your vitals are stable, you can tolerate oral liquids and your pain and nausea are controlled.
