ENDOSCOPIC SUBMUCOSAL DISSECTION

 

Endoscopic submucosal dissestion (ESD) is a procedure performed to remove the tumors from the gastrointestinal tract which have not yet entered the layers of the muscle. It is also a therapeutic endoscopic procedure useful for superficial gastrointestinal neoplasms. Endoscopic submucosal dissection is performed for various internal organs such as esophagus, stomach and colon.

Endoscopic submucosal dissestion is performed to remove the non-cancerous growths which are present on the lining of the colon or on the rectum. This procedure is also used to remove certain colorectal tumors. ESD is a minimally invasive procedure used for the treatment of colorectal cancer.

The tube is either inserted through the mouth or through the anus. The lesions are removed from the stomach and the colon.

ESD procedure consists of 3 steps. They are:

  • To observe the lesion clearly, the lesion is elevated by injecting a fluid into the submucosal layer.
