Video Summary

In this video, Mitaka Saito from National Cancer Center in Tokyo, along with Seiichiro Abe and Professor Toyonaga from Kobe University, demonstrate how to perform gastric endoscopic submucosal dissection (ESD) using a pig stomach model. They use an IT knife 2 and ORISE Pro Knife for the procedure. They begin by injecting a solution to create a submucosal cushion and then make an incision using the ORISE Pro Knife. They proceed with the ESD using the IT knife 2, making cuts from the far side to the near side while suctioning the air. They emphasize the importance of stretching the mucosa and performing dissection on both sides. They also mention the need to coagulate vessels when necessary. After completing the dissection, they demonstrate how to retrieve the specimen and attach a traction device called track motion for the second region. With the traction device, they show how it provides better visualization and helps in the dissection. They highlight the importance of finding and following the edge of the dissection plane. They successfully complete the procedure and obtain a specimen. Despite some minor muscle damage, they consider it a successful dissection. The video concludes with a view of the retrieved specimen.
