What is EMR?:
EMR is a technique used during a colonoscopy to remove large or flat polyps that are too big to be removed with standard polypectomy techniques.
It involves lifting the polyp from the deeper layers of the bowel wall and then cutting it out, all done via an endoscope.
Indications for EMR:
EMR is typically recommended for large colonic polyps, especially those that are too big to be removed safely in one piece using conventional polypectomy.
It is also used for polyps that have a high risk of containing cancerous cells but have not yet invaded the deeper layers of the colon wall.
Procedure Details:
Before the procedure, patients will need to follow a bowel preparation process to clear the colon.During the procedure, a liquid solution is injected under the polyp to create a cushion and lift it away from the deeper tissue.Then, specialised instruments are used to remove the polyp. The procedure is performed under sedation to ensure patient comfort.
Benefits of EMR:
EMR is less invasive than surgery, which typically means a quicker recovery time.
There is a lower risk of complications compared to traditional surgery.
It allows for the removal of polyps that might otherwise require more extensive surgical procedures.
Risks and Complications:
Potential risks include bleeding, perforation of the colon, and post-procedure pain.
There is also a small risk of leaving behind parts of the polyp, which could require additional procedures.
Recovery and Aftercare:
Patients can usually go home the same day after the procedure.
It's common to experience mild discomfort or bloating after the procedure, which typically resolves quickly.
Patients are advised to avoid certain medications and strenuous activities for a short period after EMR.
Follow-Up:
Follow-up is crucial to check for any residual polyp tissue and to ensure complete removal. Standard follow-up includes a colonoscopy at 6 months following resection and if there is no polyp regrowth repeating the colonoscopy in 12 months after that. If there is no recurrence at this point a colonoscopy is then recommended in 3 years.
Regular colonoscopies may be recommended to monitor for new polyps.
Lifestyle Considerations:
After EMR, patients are generally advised to maintain a healthy lifestyle to reduce the risk of further polyps.
This includes a balanced diet rich in fibre, regular exercise, and avoiding smoking and excessive alcohol consumption.
