esection) removes a

tumor with an endoscope that has a wire loop called

a snare. There is more than one method of how to do

EMR. The methods mainly differ by what devices are

used with the snare to remove the tumor.

Sometimes EMR is all that is needed to remove

a tumor. Other times, the tissue removed by EMR

helps with diagnosis but more treatment is needed.

Some tumors may be removed in multiple pieces with

EMR. However, the larger and deeper a tumor is, the

higher the risk of the tumor returning (recurrence).

Therefore, an expert endoscopist will only perform

EMR on people who are most likely to benefit.

EMR requires that you be sedated but some people

do receive general anesthesia. The procedure can

take about 1 hour to complete. EMR is generally an

outpatient procedure. However, you may stay in the

hospital for 1 or 2 days.
