Polyp resection with EMR

Depending on the size, location and complexity of the polyp, the endoscopist may opt for a classic polyp resection with snare, for endoscopic submucosal dissection (ESD) or for piecemeal endoscopic mucosal resection (EMR).

The choice for ESD or EMR is always taken in consultation with your attending physician and after considering many factors.

Endoscopic mucosal resection (EMR)

Another option for the removal of large polyps is endoscopic mucosal resection (EMR). Again, a fluid is injected between the polyp and the underlying muscle layer, allowing the polyp to be safely caught with a loop. The polyp is cut through completely and, depending on the size, this can be done in pieces, a so-called ‘piecemeal EMR’. The final result is, of course, that no remaining polyp tissue can be seen.

The major advantage of this procedure is that polyp removal is significantly faster than with an ESD and carries less risk of complications. However, compared to ESD, the polyp will usually have to be analysed in the form of separate pieces, which may be more complicated for the pathologist. Additionally, the risk is higher that microscopically small pieces of the polyp remain in place which will grow back.
