Endoscopic mucosal resection is a safer, more efficient way to remove large polyps found during a colonoscopy.
If your doctor finds a large polyp or colorectal lesion during your colonoscopy, they may recommend endoscopic mucosal resection to remove it.
What To Expect When You Have Endoscopic Mucosal Resection
Endoscopic mucosal resection (EMR) is a technique used to remove large colorectal lesions. In the past, the only option to remove large polyps was surgery. But EMR is now considered the safest method for removing this type of polyp.
Endoscopic mucosal resection is usually done during a colonoscopy or flexible sigmoidoscopy. Your doctor will pass a special needle through the colonoscope and insert it under the base of the polyp. Fluid is injected under the polyp producing a small amount of liquid that lifts the polyp off the lining of the bowel. Then, your doctor uses a wire snare (or lasso) to pull the polyp tight while an electric current passes through the snare, cuts the polyp off and cauterizes any blood vessels.
If the polyp is very large, it may be removed in a number of pieces in the same way. Once the polyp has been removed, it is retrieved so that it can be sent to the pathology lab for further analysis.
It can take up to 7 to 10 days before a result is available. Your doctor will work with you to make a decision about further treatment after reviewing results.
