Video Summary

In this video discussion, the speakers discuss their experiences and opinions on cold-snare polypectomy and underwater polypectomy. They mention that there is a paper on cold-snare polypectomy underwater, but they have not personally tried it. They discuss the benefits of cold-snare polypectomy, such as its ability to strip the mucosal layer without cutting into the submucosa. They also mention the importance of submucosal injection to loosen the submucosa and explain that pseudo-underwater techniques can be used when having difficulty grabbing an area. The speakers also discuss the prep for underwater polypectomy and suggest that a normal prep is sufficient. They discuss the risk of perforation with underwater polypectomy and mention that the rate of perforation seems to be very low but can be managed if it occurs. They also discuss the use of warm water in water exchange and water immersion colonoscopy and its effect on peristalsis. The speakers mention their snare preferences, including the use of monofilament stiff snares for underwater polypectomy and the use of 15mm or smaller snares for cold-snare polypectomy. They also discuss the issue of residual tissue after cold-snare polypectomy and the need for further treatment or observation. The speakers address questions from the audience about residual tissue after cold-snare polypectomy, sedation choices for underwater polypectomy, and the use of other techniques in conjunction with cold snaring. Overall, the speakers provide insights into their experiences and preferences with cold-snare and underwater polypectomy. (No credits granted)
