Endoscopic Submucosal Dissection (ESD)

Introduction ESD

Endoscopic Submucosal Dissection (ESD) is a non-invasive 
procedure that uses a flexible endoscope to remove precancerous 
and cancerous areas in the gastrointestinal (GI) tract.

This procedure leaves no scars on the outside of the patient's body, 
has a fast recovery rate, and a short hospital stay.

It is generally recommended for lesions larger than 20mm 
in diameter without lymph node metastasis.

ESD Procedure

step 01
Marking
Marking

Make dots using a dual knife around the lesion

step 02
Injection
Injection

Inject fluid to submucosal layer under lesion

step 03
Pre-cutting
Precutting

Cut mucosal layer along the marking dots  around the lesion

step 04
Pre-dissection
Pre-dissection

Dissect the submucosal layer under the lesion

step 05
Major dissection
Major dissection

Push endoscope deeper under the lesioned  mucosal layer and continue the dissection

step 06
Closing
Closing

Close the mucosal perforation using clips or a  stitching device

Clinical Issue of ESD

Blind Dissection
 

Without direct visual guidance, there's a higher risk of unintentional damage  to surrounding tissues, blood vessels and perforation issues

The lack of direct visualization may lead to a longer surgical time compared  to procedures where visual guidance is available

Large Size Wound Closing
 

Closure of mucosal wound caused after ESD increases the patient's recovery  speed and shortens the hospitalization period

When attempting to close a mucosal wound larger than the opening width of  the clip, endoscopists often encounter difficulty and achieve a lower rate  of complete closure
