ASGE-JGES Endoscopic Submucosal Dissection ESD (On-demand) | October 2025-LAB - Conventional ESD Techniques

LAB - Conventional ESD Techniques - IT Knife

Video Transcription

Video Summary

In this virtual lab session, Drs. Hara, Sano, and Takizawa demonstrate conventional endoscopic submucosal dissection (ESD) techniques using four different knives, focusing on the IT knife with its insulated ceramic tip for safe mucosal dissection. Dr. Takizawa shows detailed steps including injection with hyaluronic acid, mucosal incision with a dual knife, and effective tissue dissection using tension and traction methods. The discussion highlights the preferred use of IT knife in gastric regions, strategies for difficult anatomy, and traction techniques like clip traction and grip traction, especially in esophageal and gastric ESD. The live demonstration emphasizes precision, safety, and expert handling to achieve efficient resections.
