The Endoscopic mucosal resection (RME) It is a technique that allows the removal of certain superficial lesions of the digestive tract through endoscopy, avoiding in many cases the need for surgery.
The RME It is used primarily to remove polyps and other lesions located in the superficial layers of the digestive wall.
During the procedure, the specialist accesses the lesion through an endoscope and separates it from the deeper layers in order to safely remove it. The extracted lesion can then be sent to Pathological Anatomy for detailed analysis and confirmation of its nature.
It can be used to treat:
- Polyps and superficial lesions of the colon and rectum.
- Certain superficial injuries of the stomach.
- Some early injuries of the esophagus.
- Polyps or selected lesions of the duodenum.
- Other superficial alterations of the digestive tract that can be removed through endoscopy.
Practical example: removing a polyp during an endoscopy
During one Colonoscopy A polyp of a size or with characteristics that make its removal advisable can be detected.
To perform the resection, the specialist can inject a solution under the lesion that allows it to be raised and separated from the deeper layers of the intestinal wall. Then, it is wrapped with a special handle and removed using the endoscope.
Once the injury has healed, it can be examined under a microscope. This study allows us to more accurately determine what type of tissue it formed and to determine whether any further follow-up is necessary.
Endoscopic mucosal resection and advanced digestive endoscopy
Endoscopic mucosal resection is part of the Advanced therapeutic endoscopy techniques. Its main advantage is that it allows for the treatment of certain injuries from within the digestive system, without requiring conventional surgical intervention.
The choice of this technique depends on the size, location, and characteristics of the lesion. In some cases, when the alteration is more extensive or affects deeper layers, more advanced endoscopic techniques may be necessary.
A common misconception is that any polyp or lesion can be removed by surgery. endoscopic mucosal resection. In reality, before indicating the procedure, it is necessary to assess its characteristics in order to determine which technique allows for a proper and safe removal.
