Endoscopic submucosal dissection

What is Endoscopic submucosal dissection?

Endoscopic submucosal dissection is a minimally invasive advanced endoscopic procedure which is used to remove or resect pre-cancerous or early cancerous lesions of the gastrointestinal tract (GI).

Endoscopic submucosal dissection

It is done under general anesthesia and is done mostly on an outpatient basis. It is done using a high-definition upper GI endoscope either through the mouth or anus (depending on the location of the tumor).

The upper-most lining of the GI tract is the mucosa and the layer below it is the submucosa. Lesions or masses originating from this layer can be managed only with this procedure.

The procedure uses an electrical current-based surgical knife’ to remove the mass. Any minor bleeding is also cauterized and the entire mass is resected under real-time visualization

The tissue which is excised is then sent for histopathological examination.

Indications: –

1. Early cancers or micro-invasive cancers of the upper gastrointestinal tract like the esophagus,
stomach, or duodenum

2. Masses or polyps in the lower gastrointestinal tract, especially neoplastic polyps

3. Pre-cancerous lesions like Barrett’s esophagus

Advantages of ESD over surgery

1. Minimally invasive procedure

2. Complete resection prevents the spread of cancer

3. Accurate staging and grading

4. Minimal stay in the hospital (1-2 days max)

5. No complications

6. Excellent prognosis
