Endoscopic Mucosal Resection (EMR) is a procedure in which an endoscope is guided through the digestive tract to remove the abnormal tissues and lesions in the mucosa (the innermost lining of the oesophagus which extends through the gastro intestinal tract).
This technique enables location, removal and examination of these tissues with minimal invasion. EMR may be also be used to detect precancerous or early cancer lesions and determine whether mucosa is invaded by cancer lesions.
Endoscopic mucosal resection is used for diagnosis and treatment of abnormalities/early malignancies of the gastrointestinal tract.
The procedure is also used for removing tissue samples for examination which will provide accurate staging of gastrointestinal neoplasms.
This technique is used for removing superficial gastrointestinal neoplasm/early stage gastrointestinal cancers through minimal invasion.
It can help to determine if cancer has grown beneath the tissues of the digestive tract lining.
Your doctor will ask the following:
Medicines that affect blood clotting or are immunosuppressive must be stopped 2 weeks prior to the surgery.
Any drug allergies or pre-existing medical conditions must be discussed with the treating doctor.
You must not eat or drink anything for 8-10 hours prior to the surgery.
You may be given a laxative to clean the colon.
Endoscopic Mucosal Resection (EMR) is generally carried out as an outpatient procedure by an experience surgical gastroenterologist.
Commoly following is the approach:
To begin with you will be asked to gargle a solution that will act as local anesthesia for your throat. This will be followed by sedatives to relax you during the procedure.
The endoscope (a long narrow tube with a camera, light and other instruments attached to it) is inserted through the mouth up to the affected part of the gastrointestinal tract.
When lesions have to be removed from the colon, the tube is guided through the anus.
Then a fluid is injected below the lesion to lift it above the surrounding tissue and mucosa and then it is removed.
In most cases, the area is marked for future examinations.
Clear liquids are given on the day of the surgery. Gradually semi solid diet will be introduced. For next 1 to 2 days you may have a sore throat or cramps.
Risk and Complication
There is risk of excessive bleeding during the procedure. The wall of the digestive tract may get perforated during resection, especially when the lesion is a large one. Scarring may occur, which narrows the oesophagus and causes difficulty in swallowing.
If the lesion fails to elevate above the surrounding mucosa, it is a clear indicator of sub mucosal invasion of cancerous cells.
