Video Summary

In this video, Dr. Norio Fukami demonstrates how to use the Dual Knife-J for endoscopic submucosal dissection (ESD) procedures. The Dual Knife-J is a device that has multiple functions, including marking, hemostasis, and injection capability. Dr. Fukami explains that the device can be used for minor bleeding with the closed tip or with severe bleeding using coagulasper or other coagulation forceps. He also demonstrates how to give additional fluid cushion using the foot pedal, which is one of the merits of the Dual Knife-J. Dr. Fukami shows the technique of making a marking dot as a target region using the cross tip of the knife. He emphasizes the importance of keeping the endoscope straight to transmit the movement of the hand to the tip of the endoscope. He also discusses the importance of controlling both the up-down and right-left channels during the procedure. Dr. Fukami demonstrates the technique of making a mucosal incision and a submucosal pocket using the Dual Knife-J, as well as the technique of submucosal dissection. He also provides tips for controlling the depth of the incision and submucosal dissection, and for managing bleeding during the procedure. Dr. Fukami concludes by showing how to complete the procedure and check the resected specimen for any irregularities. The procedure is performed on an isolated pig stomach for training purposes.
