What is endoscopic submucosal dissection procedure?

Endoscopic submucosal dissection (ESD) is a minimally invasive procedure that uses a flexible, tube-like tool called an endoscope to remove precancerous and cancerous areas in the gastrointestinal (GI) tract. “Submucosal” means this procedure targets tumors located under the lining of the GI tract (mucosa).

Is endoscopic submucosal dissection safe?

Conclusion: In our hands, ESD is a safe and effective resection technique for large colorectal neoplasms. As experience with the technique increases, it might gradually replace piecemeal EMR in the majority of cases.

What is the difference between resection and dissection?

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.

How is an endoscopic mucosal resection performed?

Endoscopic mucosal resection is performed with a long, narrow tube equipped with a light, video camera and other instruments. During EMR of the upper digestive tract, the tube (endoscope) is passed down your throat to reach an abnormality in your esophagus, stomach or upper part of the small intestine (duodenum).

What is colonoscopy with endoscopic mucosal resection?

An endoscopic mucosal resection (EMR) is a technique performed during a colonoscopy in which large and usually flat polyps are removed. Historically, patients have often required bowel surgery to remove these particular lesions.

Is a submucosal tumor cancerous?

Submucosal nodules can be benign, precancerous, or cancerous. They often have no symptoms and are only found incidentally during a diagnostic or screening test for other conditions. Symptoms do present in some cases, however, and they vary depending on the type and location of the growth.
