Video Summary

In this video, Dr. Takashi Toyono and Dr. Sakaguchi from Kobe University demonstrate endoscopic procedures in the stomach. They begin by creating two regions near the greater curve side and in the retroflex position. Dr. Toyono explains the use of normal saline without color for better observation of the submucosal layer. They then proceed with submucosal dissection using a flash knife and end-cut mode, emphasizing the importance of creating a starting point and conducting the procedure in three steps for beginners. Dr. Toyono demonstrates how to control the insertion depth and incision level, as well as the technique for smooth and precise incisions. They also discuss the use of traction devices for difficult cases and highlight the advantages of the pocket creation method for submucosal dissection, including creating a wider opening and better control of the scope. They show how to use a clip and dental floss to provide traction in the pocket creation technique, and Dr. Toyono demonstrates the tunneling technique for creating a pocket and dissection of the submucosa. They conclude by discussing the challenges of opening the remaining mucosa and how to overcome them using retroflexion and counter-directional traction. Overall, the video provides detailed insights into endoscopic procedures in the stomach and techniques for safe and effective submucosal dissection.
