How do you perform an endoscopic submucosal dissection?
Use an electrosurgical knife with a high-frequency electrical current to “cut” tumor tissue free from the GI wall, then continue to use the electrosurgical knife to cut away the tumor. The electrical current stops any active bleeding. Remove the tissue from the body through the endoscope and send it to a laboratory.
How long does an endoscopic submucosal dissection take?
Your procedure usually takes 1 to 3 hours, but sometimes may be longer.
What is the difference between EMR and ESD?
A principle EMR consists of three steps: marking, lifting, and cutting. ESD is a newly developed technique in which submucosal dissection is carried out using an electrocautery knife to acquire a single-piece specimen, it is developed for en bloc removal of large (usually more than 2 cm), flat GI tract lesions.

What is a EMR procedure?
Gastrointestinal endoscopic mucosal resection (EMR) is a procedure to remove precancerous, early-stage cancer or other abnormal tissues (lesions) from the digestive tract. Endoscopic mucosal resection is performed with a long, narrow tube equipped with a light, video camera and other instruments.
What is the difference between dissection and resection?
Resection: This is a surgical procedure used to remove a part of an organ or a structure, possibly because of disease or cancer (e.g., the tumor resected after chemotherapy). Dissection: This is a procedure of cuts apart or separates tissue for further study or diagnosis.
Who performs endoscopic mucosal resection?
Endoscopic mucosal resection is usually performed by a specialist in digestive system disorders (gastroenterologist) who has expertise in this technique.
How long does it take to recover from endoscopic resection?
What Is the Recovery Time? Patients are discharged from the Mass General endoscopy unit with prescriptions for oral pain medications and an oral numbing solution they may use for five to seven days. A modified diet is recommended for the first three days after the procedure to allow time for healing.
How long does it take to recover from an endoscopic mucosal resection?
How do you prepare for endoscopic mucosal resection?
Preparing for Endoscopic Mucosal Resection
- For a lower GI tract procedure, follow a liquid diet plus a laxative or enema to cleanse the bowel.
- For an upper GI tract procedure, do not eat or drink for 12 hours before the procedure to ensure your esophagus is clear of food.
- Tell your doctor if you have any allergies.
Do you gag when having an endoscopy?
It is normal to gag, but the reflex usually settles once the tube is passed. It is also common for the first attempt at swallowing not to succeed. With the encouragement of the endoscopy nurse and perhaps some maneuvers by the endoscopist, the tube will pass.
