Endoscopic Mucosal Resection (EMR) is a technique used to remove tumors, polyps, or abnormal tissues from the mucosa of the gastrointestinal tract. This procedure is performed using an endoscope, which allows the surgeon to access the target area through small incisions or natural openings, such as the mouth or anus.

EMR is typically used for early-stage cancers, precancerous lesions, or benign growths in the digestive tract, including the esophagus, stomach, or colon. The procedure involves injecting a solution under the mucosal layer to lift the lesion, followed by cutting and removing the tissue.

Postoperative care includes monitoring for bleeding or infection, along with following a special diet to allow the digestive system to heal. Follow-up endoscopic exams are often scheduled to ensure that all abnormal tissue has been removed.

Endoscopic mucosal resection is an effective, minimally invasive option for removing certain tumors and polyps, offering patients quicker recovery and lower complication rates compared to traditional surgery.
