What are EMR and ESD?
Gastrointestinal EMR and ESD are specific highly specialised techniques used to remove abnormal growths (precancerous or early cancers) from within the digestive tract. Your doctor may refer you to NSG for these procedures if they identify such a lesion at the time of your endoscopy or colonoscopy.
The kinds of lesions that may require EMR or ESD include:
- Barrett’s oesophagus
- Early oesophageal cancer
- Early stomach cancer
- Large polyps in the colon or rectum
What does EMR or ESD involve?
The procedure is performed under intravenous anaesthesia by a specialist anaesthetist. Once you are under anaesthetic, a flexible endoscope is passing into the digestive tract through the mouth or anus to reach the known lesion. Specialised endoscopic cutting devices are used to carefully and completely remove the targeted lesion following separation of the gut layers using a viscous solution to minimise the risks of complications.
How do I prepare for my EMR or ESD?
This will depend upon whether the procedure involves a lesion in the upper gut, or in the colon or rectum. If the latter, in addition to the routine pre-procedure fasting, you will need a bowel cleanse like you have for a colonoscopy. You should advise us if you are taking blood thinners or diabetic medication.
What are the possible risks of EMR or ESD?
Your doctor will explain the procedure and risks in detail, as these vary depending upon the size and location of the lesion being treated.
Is EMR or ESD a day procedure?
Most EMR and ESD cases are same-day procedures. Your doctor may advise overnight admission following the procedure for observation as a routine precaution.
