Endoscopic mucosal resection (EMR)
EMR in Istanbul: what happens before and after a large bowel polyp is removed?

Questions about colorectal EMR for large polyps: suitability, alternatives, risks, pathology and the importance of planned surveillance.
Before your assessment
A referral for endoscopic mucosal resection can leave you with three unfamiliar letters and plenty of questions. Start with this one: “What do we know about the polyp, and what will we learn after it is removed?”
This guide focuses on colorectal EMR. Procedures in the stomach or oesophagus have different considerations.
What does EMR involve?
EMR removes selected abnormal tissue through an endoscope. In conventional bowel EMR, fluid can be injected beneath the polyp to separate it from deeper layers, then a wire loop removes it. Some lesions are removed in several pieces. This is different from removing a section of bowel surgically. United Lincolnshire Hospitals
Ask whether the plan is one-piece or piecemeal removal, and why.

Who might be suitable?
ESGE's 2024 guideline recommends conventional EMR for large, non-stalked adenomatous colorectal polyps measuring at least 20 mm. However, size alone is not a treatment decision: appearance, location and suspected invasion influence the approach. Selected lesions need a different technique or expert-centre review. ESGE 2024
“Large”, “complex” and “cancerous” do not mean the same thing. A useful consultation should explain the specific finding rather than simply offer a package.

Is EMR always preferable to ESD or surgery?
No. When superficial invasive cancer is suspected, removal in one piece may be important; ESD or another approach can be more appropriate. Deeper invasion can require surgical assessment. These choices need specialist evaluation, not a ranking of procedures from “basic” to “advanced”. ESGE 2024
Questions to take to the appointment:
• Why does this method fit my lesion?
• Would a second endoscopic opinion change the plan?
• What are the consequences of delaying or declining treatment?
• What happens if removal cannot be completed?

What risks should I understand?
Bleeding and a hole in the bowel wall are important risks. Complications can require further endoscopy, hospital care or surgery. Risk varies with the lesion and your health; an average from another hospital is not your personal estimate. United Lincolnshire Hospitals
Report medicines, allergies and previous sedation problems. Request individual bowel-preparation and medication instructions; do not change prescriptions yourself. The preparation and recovery plan should come from the treating team. Worcestershire Acute Hospitals
Why does pathology still matter after removal?
The removed tissue is examined in a laboratory. Findings may change the need for further investigation or treatment. Incomplete removal may also require another procedure. Leaving the endoscopy unit is therefore not the same as completing care. Worcestershire Acute Hospitals
Before discharge, agree who will explain the pathology, how you will receive it, and whom to contact if it has not arrived.

When is the next colonoscopy?
The interval depends on the findings and how removal was performed. ESGE's surveillance guideline recommends an early repeat colonoscopy after 3–6 months following piecemeal removal of polyps at least 20 mm, followed by surveillance 12 months after that repeat examination. This is not a universal timetable for every EMR. ESGE surveillance guideline
Ask for your own written schedule and a named clinician responsible for arranging it.

What should I plan for recovery?
Arrange an escort if sedation is used and follow the team's driving and activity restrictions. Severe abdominal pain, persistent or heavy rectal bleeding, fainting or fever need urgent medical assessment. Do not wait for a coordinator in an emergency. United Lincolnshire Hospitals

How can I coordinate an assessment in Istanbul, Turkey?
Unimed's supplied Prof. Dr. Barış Yılmaz profile lists EMR among his applications. This editorial guide does not claim his review or confirm current procedure availability.
Ask how to transfer existing colonoscopy images, reports and pathology confidentially. Confirm the treating hospital, clinician, sedation arrangements, written estimate and follow-up at home. Travel timing must be agreed clinically; this guide does not offer a fixed stay, price or result.
Contact Unimed on WhatsApp: +90 545 234 63 74 for coordination. Do not post medical records in public comments.
Frequently asked questions
Does a large polyp automatically mean cancer?
No. Assessment and tissue examination are needed; size alone does not provide the diagnosis.
Can I book my flight before the treatment plan is confirmed?
Ask the treating team first, including what would happen if observation, further treatment or a delayed return were necessary.
Does removal mean I can skip follow-up?
No. Obtain the pathology review and the surveillance plan relevant to your case.

Have reports for this procedure?
Send them for a confidential specialist review. A coordinator confirms what is missing and when the doctor's view will be ready.
