Video Summary

In this video, the presenter demonstrates the tunnel method during endoscopy to remove a gastric lesion. The presenter begins by marking the area with a pro-knife and then switches to a force-coag to create the marking. They explain that they are using a smaller caliber device that allows them to do retroflexion in the gastric area. They then demonstrate the use of speedboat, a device with the capability of radiofrequency cut and microwave coagulation. Throughout the procedure, they emphasize the importance of controlling the depth of cutting and recognizing the lifting sign during submucosal injection. They also demonstrate different cutting modes and explain that the procedure requires a certain level of experience to control the device properly. They discuss the benefits of the tunnel method, such as easy access to the submucosal space and the ability to control bleeding through coagulation. They also mention that the method can be used for colonic lesions and in regions with undulated areas. The presenter concludes by discussing the importance of strategic incisions and utilizing additional traction methods for larger lesions.
