Video Summary

In this video, Naofisayo Hagi from Keio University demonstrates two traction techniques for performing endoscopic submucosal dissection (ESD). The first technique is the creep line traction method, while the second technique is the water pressure method. Hagi explains that the creep line technique is used in difficult-to-access areas and involves creating a submucosal fluid cushion to facilitate ESD. The water pressure method, on the other hand, is used in regions located on the gravity side, such as the duodenum, where gravity is not effective in creating traction. Hagi demonstrates the mucosal incision and submucosal dissection steps using both techniques, highlighting the importance of maintaining a straight endoscope position and keeping the ceramic tip on the mucosal surface. He also addresses questions from Dr. Kato and other panelists regarding the choice of incision mode, use of pocket creation method, instrument preferences, and overcoming challenges in dissection. Overall, the video provides a detailed overview of these two traction techniques for conducting ESD procedures.
