EMR (Endoscopic Mucosal Resection)
Endoscopic Mucosal Resection (EMR) is a minimally invasive endoscopic procedure used to remove selected abnormal, precancerous, or early-stage lesions from the superficial lining of the digestive tract. The procedure allows targeted tissue removal through an endoscope without the need for conventional open surgery in appropriately selected patients.
1. Patient Evaluation
Before EMR, a detailed clinical assessment is performed to evaluate the patient's symptoms, medical history, and the characteristics of the identified lesion. The size, location, appearance, and depth of the lesion are carefully considered.
2. Pre-Procedure Assessment
The patient may require blood tests, diagnostic endoscopy, biopsy, or imaging studies depending on the clinical situation. Current medications and other medical conditions are also reviewed to ensure appropriate preparation for the procedure.
3. Endoscopic Examination
A specialized endoscope is introduced into the digestive tract to obtain a detailed view of the lesion. The specialist carefully assesses the lesion and identifies its boundaries before beginning the removal process.
4. Lesion Identification & Marking
The area to be removed is clearly identified and, when appropriate, marked around its margins. This helps the specialist accurately target the abnormal tissue while preserving as much healthy surrounding tissue as possible.
5. Submucosal Injection
A suitable solution may be injected beneath the lesion to lift it away from the deeper layers of the digestive tract. This creates a safer working space and facilitates controlled removal of the targeted tissue.
6. Mucosal Resection
Using specialized endoscopic instruments, the raised lesion is carefully captured and removed from the mucosal layer. Depending on the size and characteristics of the lesion, the tissue may be removed in one piece or in multiple sections.
7. Bleeding Control
After removal, the treatment area is carefully inspected for bleeding or other immediate concerns. Endoscopic techniques may be used to control bleeding and promote safe healing when required.
8. Tissue Collection & Pathology
The removed tissue is collected and sent for histopathological examination. Laboratory assessment helps determine the exact nature of the lesion, its depth, and whether the removal appears complete.
9. Post-Procedure Monitoring
Following EMR, the patient is monitored during recovery for any immediate complications. Instructions regarding diet, medications, warning signs, and activity are provided according to the individual procedure and clinical condition.
10. Follow-Up Care
Follow-up may include repeat endoscopy, pathology review, and additional treatment or surveillance depending on the final results. Regular monitoring is particularly important for lesions with precancerous or early malignant features.
Benefits of EMR
EMR provides a minimally invasive option for removing selected superficial gastrointestinal lesions. It can help obtain tissue for accurate diagnosis while treating the targeted lesion and, in appropriate cases, avoiding more invasive surgical procedures.
Comprehensive EMR Care
Our EMR service focuses on careful patient selection, detailed endoscopic assessment, precise lesion removal, bleeding management, pathological evaluation, post-procedure monitoring, and appropriate follow-up care. The suitability of EMR is determined individually based on the lesion and the patient's overall clinical condition.
