ASGE/JGES Advanced ESD (On-demand)| July 2023-Lab Hands-On Virtual Demonstration Part 1

Video Transcription

Video Summary

In this video, Yutaka Saito, Seiichi Rabe, and Toyonaga demonstrate the use of gastric PST (per-oral partial thickness dissection) using an isolated pig stomach. They begin by using the O-Rise Pro-Knife for the first marginal incision, followed by the IT-Knife 2 for marginal incision and causal dissection. They also demonstrate the use of dental floss traction for better visualization. They then move on to show the ESD (endoscopic submucosal dissection) using a retroflex position with a marking already conducted. They perform causal injection using the O-Rise Gel and proceed with incisions using the O-Rise Pro-Knife and IT-Knife 2. Various techniques and tools are discussed, including the use of IT-Knife 2 for cut, coagulation, and visualization, the importance of deep incisions for musculoskeletal causes, and the recommended use of the near-side approach to prevent bleeding. The video ends with a demonstration of Fuji double channel scope with track motion, showing the attachment and use of the device for traction during the ESD procedure.
