EMR - Endoscopic Mucosal Resection

An infusion will be placed in the room and you will be asked to remove your glasses/contact lenses and dental prosthesis.

A patient apron will be ready to wear.

Female patients will be asked to take off their bra.

You must be sober at least 6 hours before the exam. This means no eating, drinking or smoking.

If the injury is in the colon, it must first be rinsed clean, either by a specific complete bowel preparation or by a prior anal lavement (see preparation for a bowel exam).

• If this has not happened in the room yet, the nurse in the endoscopy department will puncture a vein in the arm so that the anaesthetist can administer the anaesthetic.
• This examination takes place under general anesthesia. In some cases, the doctor will decide to keep you in hospital for one night to observe.
• Ask a family member/acquaintance to take you home after the examination. After a general anaesthetic, you are not allowed to drive a vehicle. Do not plan important activities after the investigation. Your concentration and assessment may have been reduced.
• During the examination, you will lie on the left side. During an oral examination, a mouthpiece between the teeth/lips prevents you from biting the endoscope.
• The anaesthetist places a tube in the airway to take over breathing.
• During the study, the oxygen level in the blood is continuously measured. This is done with a measuring device that is placed on the finger. You will receive oxygen glasses on the nose

The treatment

Using a thin needle, the doctor injects fluid below the site where the abnormality is located.
This creates a ball. This ball is drawn up using a transparent cap at the end of the endoscope. The doctor then places a loop around the ball with a power wire and gently tightens the loop. Power is now being fed through the power wire. As a result, the ball is burned away from the underlying layer. This is sometimes repeated several times for larger injuries.
The average duration of the study is 30 - 60 minutes.
The injury is stored and sent to the lab for microscopic examination.

• After the examination, you will be taken to the awakening room of the endoscopy department. There, the oxygen level in the blood is further monitored.
• A raw feeling in the throat is possible for some time after the examination by mouth.
• You may also have bloating due to the carbon dioxide that was blown in during the examination. Farming up or letting go can offer rapid improvement.
• Nausea is also possible.

Bleeding: a blood vessel may be affected during treatment. This can cause bleeding. This happens in an average of 10 percent of the cases. In that case, this bleeding will be treated immediately so that blood loss is limited. Late bleeding occurs in approximately 5 to 10 percent of the procedures.

• Perforation: occurs very rarely, in 0.3 to 0.5 percent of the procedures.
• Anaesthesia: see anaesthesia booklet (No. 0520 1167) in the annexes below.
