What is EMR?
Endoscopic Mucosal Resection (EMR) is an advanced endoscopic technique used to remove large, flat polyps and early cancers from the lining of the gastrointestinal tract. Fluid is injected beneath the lesion to lift it from the underlying muscle layer, and it is then removed using a special snare.
When is EMR recommended?
- Large flat or sessile polyps (typically >20mm) found during colonoscopy
- Early superficial cancers confined to the mucosal layer
- Laterally spreading tumours
- Lesions that are too large for conventional snare polypectomy
EMR vs ESD
While EMR is highly effective for most large polyps, some complex lesions may benefit from Endoscopic Submucosal Dissection (ESD), which allows en-bloc (single-piece) removal. A/Prof Kostalas will assess your lesion and recommend the most appropriate technique based on its size, location, and features.
The Procedure
EMR is typically performed during a colonoscopy under sedation. For very large lesions, the procedure may take longer than a standard colonoscopy. Most patients can go home the same day, though some may require overnight observation depending on the size and location of the removed lesion.
