Endoscopic mucosal resection (EMR) is a highly-specialized procedure for the staging and removal of cancerous or other abnormal tissues from the digestive tract. Your physician inserts a lighted flexible scope into your mouth or anus (depending on the location of the abnormality), identifies the lesion and removes it with various tools inserted through the endoscope. These tissue samples are sent to a laboratory for examination and your physician will notify you with the results.
EMR is performed on lesions in the digestive tract that are large and/or contain abnormal cells (including cancer). EMR helps clarify the diagnosis, helps stage cancers, and can eliminate the need for more invasive surgery.
You will be sedated for the EMR procedure and will need to follow any pre-procedure instructions from your physician regarding fasting or medication restriction.
