Two typical cases of protruding tumors resected by endoscopic submucosal dissection.

The rate of severe fibrosis was significantly higher in protruding tumors (19.4 %), followed by LST-NG (4.4 %) and LST-G (3.7 %) type lesions (P = 0.001).

In Korea, there are a few companies making knives and snares for ESD, but Japanese products are more commonly used. Whenever I visit Japanese endoscopy conferences, I'm always surprised to find many brand new endoscopic devices. My question is what is the secret of Academy-Business cooperation for the development of new endoscopic products. Is there any strength in Japanese culture? Or governmental support?
