T
he endoscopic submucosal dissection is the standard of care for the management of early malignant or premalignant
neoplasm in the gastrointestinal tract. However, patients with these lesions are often accompanied with significant medical
comorbidities. Such as, patients on oral anticoagulation with high thrombotic risk e.g., mitral valve replacement, dual valve
replacement, recent myocardial infarction with intervention, end stage renal failure, poorly controlled diabetes, conditions
with high anaesthestic risk, etc. Patients with these high risk medical conditions often increase both endoscopic and non-
endoscopic complication rate. Combination of careful optimization of medical condition, pre-endoscopic preparation,
special endoscopic technique and post-endoscopic management is a must to acheive low complication rate for these high
risk population. Endoscopic techniques for prevention of rebleeding included careful identification of all vessels under indigo
carmen-free submucosal plane, precoagulation of big vessels, submucosal dissection using coagulation mode, liberal use
of coagulation forceps to eradicate all vessel heads at the post ESD wound and prophylactic closure of post ESD wound.
Endoscopic techniques for prevention of perforation included maintainance of a good and clear view (Only cut when you
see) in an indigo carmen free submucosal plane and prevention of any active bleeding, maintainance of the direction of knife
parallel to muscle layer and the direction of cutting away from the muscle layer together with a good traction and slight
hooking of tissue (ball-tube type of knife) especially when the direction of knife is perpendicular to the muscle layer. Use of
coagulation mode for submucosal dissection is also the key.
