Endoscopic Mucosal Resection, often called EMR, is a minimally invasive procedure used to remove abnormal or precancerous growths from the lining of the digestive tract. Using a flexible endoscope equipped with a camera and specialized tools, your gastroenterologist can remove polyps, early-stage tumors, or areas of abnormal tissue without the need for traditional surgery.
EMR is often recommended when abnormal tissue is found during a colonoscopy, upper endoscopy, or other digestive examination. It is commonly used to treat large or flat polyps, Barrett’s esophagus with precancerous changes, early-stage cancers limited to the surface layers of the digestive tract, or suspicious growths in the stomach, esophagus, or colon. By removing the abnormal tissue early, EMR can help prevent the development of more serious disease.
Before the procedure, you will be given preparation instructions, which may include dietary restrictions and bowel cleansing if the colon is being examined. During the procedure, sedation or anesthesia is provided for comfort. The endoscope is guided through the mouth or rectum to reach the target area. A small solution may be injected under the abnormal tissue to lift it away from the deeper layers, allowing for safe removal. Specialized tools are then used to carefully resect the tissue, which is sent for analysis. The procedure usually takes 30 to 60 minutes.
Most patients go home the same day after a short recovery period. You may experience mild bloating, cramping, or a sore throat depending on the site of the procedure. Your doctor will provide instructions on diet, activity, and follow-up care. Avoid strenuous activity for 24 hours, and arrange for someone to drive you home due to sedation. Your doctor will review pathology results and discuss whether further treatment or surveillance is needed.
EMR avoids the need for more invasive surgery in many cases, provides an effective treatment for removing large or precancerous lesions, allows tissue sampling for accurate diagnosis, promotes quicker recovery and less downtime, and reduces the risks associated with open surgical procedures.
Although EMR is considered safe, you should contact your doctor if you experience severe abdominal pain, persistent vomiting, black or bloody stools, dizziness, or fever after the procedure.
