What it is

What is Endoscopic Mucosal Resection?

Endoscopic Mucosal Resection (EMR) is an advanced endoscopic technique used to remove large, flat, or sessile polyps from the lining of the gastrointestinal tract, most commonly the colon. The procedure involves lifting the polyp by injecting a solution into the submucosal layer beneath it, creating a cushion. This elevation allows a snare to be passed around the polyp to resect it without damaging the deeper muscular layer of the colon wall. For larger polyps, this may be done in a piecemeal fashion. EMR is a minimally invasive alternative to surgery for the removal of large benign polyps and select early-stage cancers.

Am I a candidate?

Who is a Good Candidate for EMR?

EMR is ideal for patients with large (typically >2 cm), non-cancerous polyps that are too large or flat to be removed by standard polypectomy techniques. It is also a treatment option for early-stage cancers that are confined to the mucosal layer and have a low risk of lymph node metastasis. The decision to perform EMR is based on the size, location, and endoscopic appearance of the polyp, as well as the overall health of the patient.

Recovery

What is the Recovery Like?

Recovery after EMR is similar to that of a standard colonoscopy. Patients may experience mild cramping, bloating, or discomfort for a day or two. A clear liquid diet may be recommended for the first 24 hours, followed by a gradual return to a normal diet. Strenuous activity and heavy lifting are typically restricted for about one week to reduce the risk of delayed bleeding. Patients will receive specific instructions based on the size and location of the resected polyp.

Risks & considerations

What are the Risks?

While EMR is a safe procedure, it has a slightly higher risk of complications than standard polypectomy. Potential risks include:

  • Bleeding: Bleeding can occur during the procedure or in a delayed fashion, up to two weeks later. The risk is higher for larger polyps and those located in the right colon.
  • Perforation: A tear in the colon wall is a rare but serious complication that may require surgical repair.
  • Post-Polypectomy Syndrome: A rare complication involving abdominal pain, fever, and inflammation after the procedure, which typically resolves with conservative management.
  • Incomplete Resection/Recurrence: The polyp may not be completely removed, or it may recur over time, requiring further treatment or surveillance.
