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

Video Transcription

Video Summary

In this video, Dr. Kenneth F. Binmoeller discusses the use of water immersion and water exchange during colonoscopy procedures. He explains that water immersion involves leaving the gas on while infusing water to assist with progression to the cecum, while water exchange involves turning off the gas and only infusing water to maintain a clear view of the lumen. Dr. Binmoeller highlights the advantages of underwater imaging, such as better visualization of fine details, no light reflection artifacts, no fogging, and a 3D floating effect. He also discusses how water immersion can be used for underwater EMR and the benefits it offers, such as improved Boston bowel preparation scores, higher adenoma detection rates, and easier resection of difficult polyps. Dr. Binmoeller encourages endoscopists to try using water immersion and water exchange techniques and provides tips and tricks for successful implementation. He also addresses concerns about hyponatremia, emphasizing the use of saline rather than water to avoid mucus film secretion.
