ASGE Annual Postgraduate Course: Endoscopy Around the World: Video Case-Based Pearls from the Masters (On-Demand)

Video Transcription

Video Summary

In this video, Dr. Kenneth Wang discusses the technique of water immersion and water exchange during endoscopy procedures. He explains that water immersion involves leaving the gas on while infusing water to assist progression through the colon, while water exchange involves turning off the gas and infusing water to aspirate gas pockets and maintain a clear view of the lumen. Dr. Wang emphasizes the advantages of underwater imaging, including improved visualization of fine detail, absence of light reflection artifacts, 3D floating effect, and reduced fogging. He discusses the use of underwater imaging in various endoscopy procedures, such as capsule endoscopy, EMR, and EUS. He also highlights the potential benefits of water immersion, including improved bowel preparation, lower recurrence rates, and better resection of difficult polyps. Dr. Wang addresses common concerns about the technique, such as the time it takes to fill the colon with water and the risk of hyponatremia, and provides tips for successful water immersion procedures.
