 The “triangle-tip” electrocautery knife has been newly designed as a tool which can pass through the working channel of the endoscope and used for endoscopic submucosal dissection (ESD) of upper gastrointestinal intramucosal neoplasia. All processes of ESD including marking, marginal cutting, submucosal dissection and hemostasis can be performed by this single device. 199 cases of gastric cancer and 102 cases of esophageal tumor received ESD using a triangle-tip knife. In all cases ESD was successfully performed with no serious complications. We consider that this novel device is another useful endoscopic instrument for ESD. Comparative study with other devices will be a useful and necessary measure for future evaluation of ESD devices.
