ASGE JGES Primer ESD | September 2022-Hands on Virtual Demonstration Part 1

Video Transcription

Video Summary

In this video, Hironori Yamamoto from Jitsi Medical University in Japan demonstrates how to perform an endoscopic submucosal dissection (ESD) using the pocket creation method. He starts by explaining the technique for controlling the endoscope and demonstrates how to rotate and adjust the endoscope to obtain a clear view. Yamamoto also discusses the use of a special cap called the ST hood, which helps maintain a clear view during the procedure. He then proceeds to perform the ESD by injecting saline and elevating the mucosa, making a mucosal incision, and creating a submucosal pocket. He demonstrates how to control the depth and direction of the incision, as well as how to dissect the submucosa while keeping the muscle layer intact. Yamamoto emphasizes the importance of identifying and avoiding branch vessels to minimize bleeding during the procedure. He also discusses the use of post-coagulation to control bleeding and achieve a high-quality dissection. The video includes additional demonstrations by Takashi Kuroda from Kobe University Hospital, who performs an ESD using a different technique involving an initial J-shaped mucosal incision. Yamamoto concludes the video by discussing the different options and techniques available for creating the submucosal pocket and completing the dissection.
