ESD Procedure

Innovative endoscopic treatment for mucosal tumors

Endoscopic submucosal dissection (ESD) procedure is an innovative way to remove early benign or cancerous tumors of the esophagus, stomach, and colon (large intestine).

For procedures in the colon, you will need a liquid diet and bowel prep to clean your colon. For procedures in the esophagus and stomach, you will need to fast after you go to sleep the night before.

Understanding Mucosal Tumors

Mucosal tumors are tumors of the esophagus, stomach, or colon that have not yet entered the deep layer of the GI wall. Endoscopic mucosal dissection can be used to treat Barrett’s esophagus and early-stage cancerous tumors including esophageal cancer, stomach cancer and colorectal cancer.

Your doctor will do a series of tests to diagnosis mucosal tumors. Learn more about the causes and other treatment options for mucosal tumor.

How is the ESD Procedure performed?

Your doctor will do a series of tests to determine how deep your tumor is before considering treatment. Early tumors of the esophagus, stomach, or colon have not yet entered into the muscle layer of the gastrointestinal wall. ESD is a minimally invasive procedure to remove early tumors. 

For the procedure, you are put to sleep with general anesthesia. An endoscope is inserted through the mouth or the anus to the location of the tumor. Once located, your physician will mark the tumor borders, and inject fluid into the layer beneath the tumor to separate it from the muscle wall. A surgical knife will carefully cut the diseased tissue from the wall. 

After the tissue is removed, a device may be placed to ensure closure of the site. The tissue removed from the body will be sent to the laboratory for testing to determine pathology. The procedure length is dependent on the location of the tumor and the size.

Do I have to stay the night in the hospital?

This is an outpatient procedure, but there is always a chance you may have to stay overnight.

After the procedure, you will be monitored in the recovery room and your doctor will discuss your results before you leave. You will have a modified diet for about a week, and you may have activity and weight restrictions for two weeks after the procedure.

What happens when I go home? Going back to work?

You will have a modified diet for about a week, and you may have activity and weight restrictions for two weeks after the procedure.

Will I need to come back for more testing?

Follow-up care will be based upon pathology results. These results can take 1-2 weeks to come back.
