What is EMR?
Endoscopic mucosal resection is a minimally invasive, safe and well established method of removing polyps. An endoscope is introduced to the site of the polyp. Using a small needle which is passed through the channel on the endoscope, a fluid is injected underneath to raise the polyp above the intestinal lining thus creating a safe field to remove it.
A metal snare will be placed around the polyp and a small amount of current will be passed through to cut the polyp while cauterising the blood supply. If the polyp is larger, the above steps may need to be repeated until the polyp is completely removed. Metal clips may be placed after the removal at the site to assist healing and prevent complications. The polyp will be sent for analysis under the microscope.
Risks involved in EMR
EMR carries risks associated with the standard risks of any endoscopic procedures. Because of the nature of the procedure EMR also carries a small risk of perforation (a small hole/tear in the intestinal lining), bleeding, and incomplete removal. These are all explained in detail in the leaflet you will receive prior to the procedure. Fortunately these risks are rare.
What are the alternatives?
You might choose to leave the polyps untreated, but you must discuss the risks of doing so with your doctor. Secondly, removal of polyps by surgery can be considered as an option.
After the procedure
These are performed as day case procedures usually unless there is a need for a short stay in hospital. After undergoing EMR you will be given leaflets advising about the steps in case you need any help. We provide our personal mobile numbers in case of emergency.
Who will perform the procedure?
Complex EMRs are undertaken by Dr Bjorn Rembacken and Dr Noor Mohammed. We are fortunate in Leeds to have Dr Bjorn Rembacken who is internationally known in the field of endoscopic removal of complex polyps.
Other endoscopists with expertise in this technique include nurse endoscopist James Meadows, Dr Simon Everett, Dr John Hamlin, Dr V Subramanian and Mr Kallingal Riyad.
