Endoscopic Submucosal Dissection Versus Surgery in the Treatment of Early Gastric Cancer

Endoscopic submucosal dissection is an endoscopic procedure which can achieve en bloc resection of GI tumor. ESD is characterized by three steps: injecting fluid into the submucosa to elevate the lesion from the muscle layer, circumferential cutting of the surrounding mucosa of the lesion, and subsequent dissection of the connective tissue of the submucosa beneath the lesion. The ESD procedure will be carried out by experienced endoscopists.

Surgery for EGC include Distal, proximal, or total gastrectomy, which will be performed according to the location and macroscopic tumor type by experienced surgeons.
