Video Summary

In this video, a group of experts discuss the use of cold-snare polypectomy underwater. They mention that there is a paper on this technique but none of them have tried it themselves. They discuss the benefits of cold snaring, which involves removing polyps by mucosal stripping instead of cutting into the submucosa. They also mention the importance of submucosal injection to loosen the submucosa. One of the experts shares their experience with pseudo-underwater modifications to help with difficult areas. They also discuss the prep for underwater polypectomy and the potential limitations, such as solid debris. The experts also discuss the use of warm water during water exchange colonoscopy and the impact of water temperature on peristalsis. They mention that peristalsis can be helpful for underwater EMR and its role in moving polyps. The experts also address questions about injury to the muscularis propria during cold snare polypectomy underwater and the issue of perforation and leakage of liquid due to peritonitis. Overall, the video provides insights into the technique and considerations for cold-snare polypectomy underwater. No credits were mentioned in the video.
