Video Summary

In this video, Yutaka Saito, Seiichi Rabe, and Toyonaga demonstrate the live procedure of gastric PST (per-oral submucosal dissection) using an isolated pig stomach. They use the O-Rise Pro-Knife and IT-Knife 2 for incisions and dissections. The dental floss traction technique is also shown. They also demonstrate the ESD (endoscopic submucosal dissection) using a retroflex position. They explain the use of viscous solutions and the importance of deep incisions. The use of IT-Knife 2 for dissection is discussed, with emphasis on its effectiveness in gastric ESD compared to esophageal and colorectal procedures. The video also showcases the use of Fuji double-channel scope with track motion for traction during ESD. The procedure is explained, along with tips on optimal device usage and creating suitable counter traction. At the end, the effectiveness of the traction technique is demonstrated.
