Abstract
In 2000, endoscopic resection is very useful treatment modality for early gastric cancer. The Needle Knife (Olympus, Tokyo, Japan) and Insulated Tip Knife (Olympus) are used for endoscopic dissection of gastrointestinal tumors in clinical practice. The depth of penetration and the high power delivered to soft tissue by electrocautery with these needles are not well controlled, and therefore may increase the risk of complications such as intestinal perforation and bleeding lasers 2-μm in wavelength offer efficient tissue cutting with limited thermal damage in biological tissue. Light amplication by the sumulated emission of radiation dissection demonstrated good maneuverability, clean and rapid cutting, and excellent hemostasis. And, now we would like to evaluate the clinical outcomes of the endoscopic submucosal dissection with using laser and capabilities in the future.
