EMR (Endoscopic Mucosal Resection) and ESD (Endoscopic Submucosal Dissection) are both minimally invasive endoscopic procedures used to remove abnormal growths, such as polyps and early-stage cancers, from the lining of the digestive tract. However, they differ in their approach and suitability for various situations. Here’s a breakdown to help you understand which procedure might be recommended for you:
EMR is a more straightforward procedure in which a specialized snare is inserted through the endoscope to loop around the polyp's base. An electric current is then passed through the snare, cutting and removing the polyp from the digestive tract's mucosal layer (the surface lining).
EMR is a less complex procedure with a shorter recovery time than ESD.
EMR is suitable for removing smaller polyps (generally less than 2 cm) confined to the mucosal layer. It's often the preferred approach for:
• Precancerous polyps (adenomas)
• Early-stage cancers limited to the mucosa
EMR may not be suitable for larger polyps or those that have grown deeper into the submucosal layer (the tissue beneath the mucosa).
ESD is a more advanced and technically demanding procedure. It involves injecting a fluid beneath the polyp to create a submucosal cushion, allowing for better visualization and maneuverability. Specialized instruments are then used to dissect the polyp layer by layer, separating it from the deeper tissues before complete removal.
ESD offers a higher chance of complete polyp removal, especially for larger or deeper lesions, potentially reducing the risk of cancer recurrence.
ESD removes larger polyps (often exceeding 1 cm) or those that show more profound growth into the submucosal layer. It's also preferred for::
• Removing lesions with an uncertain depth of invasion
• Achieving complete en-bloc resection (removal of the entire polyp in one piece) for better cancer staging and prognosis
ESD is a more complex procedure with a longer learning curve for endoscopists. It also carries a slightly higher risk of complications compared to EMR.
Larger polyps or those in difficult-to-reach areas might be better suited for ESD.
If the polyp has grown deeper into the submucosal layer, ESD is likely recommended.
For definitive cancer diagnosis and staging, ESD may be preferred.
Your doctor will consider your medical history and suitability for a more complex procedure.
Suppose you have been diagnosed with a polyp or abnormal growth in your digestive tract. In that case, your gastroenterologist will discuss your treatment options and recommend the most suitable procedure, EMR or ESD, based on your specific case. They will explain the details of each procedure, potential risks and benefits, and help you make an informed decision about your care.
