Endoscopic Submucosal Dissection (ESD)


Endoscopic submucosal dissection or ESD is an advanced endoscopic procedure that allows for the complete removal of early tumors and cancers of the esophagus, stomach and rectum.

In 2015, trained specialists at Baylor Medicine started offering this procedure with remarkable success. ESD is not available at most practices in the Houston area.

ESD is a non-surgical technique performed by specially trained gastroenterologists who use endoscopy to dissect one piece of a superficial mucosal tumor in the esophagus, stomach or colon, leaving intact normal tissue under the resected tumor. This less invasive technique results in the complete removal of the tumor without the need for surgery.

Benefits of this procedure include:

  • En-bloc resection of the tumor regardless of size
  • Higher cure rate
  • Allows the physician to do a resection when endoscopic mucosal resection or EMR is not feasible
  • Avoids surgery

What types of lesions are candidates for ESD:

  • Early esophageal cancers (adenocarcinoma, squamous cell carcinoma)
  • High-grade dysplastic esophageal lesions with Barrett's esophagus
  • Early gastric cancers
  • Early rectal cancers
  • Large colorectal polyps
  • Rectal and gastric carcinoid tumors
