 We developed a special endoscopic knife in 1995 named “insulation-tipped diathermic knife (IT knife)”, in which we tipped a ceramic ball with the top of a needle knife. This knife can cut submucosa safely and remove a lesion completely. Now in Japan, besides the IT knife, several other types of knives have been developed and are used. Dissection with these knives is called “enodscopic submucosal dissection”. Although the IT knife has some weak points, namely technical difficulty in its use and bleeding due to incised submucosa, all patients affected received conservative treatment and none underwent emergent surgery. One-piece resection makes possible a correct recommendation for patients with early gastric cancer and the IT knife and other special knives make this possible.
