PERISTALTIC CONTRACTIONS HELP SNARING DURING UNDERWATER EMR OF COLONIC NON-GRANULAR PSEUDODEPRESSED LST

Video Transcription

Video Summary

In this video, the concept of underwater EMR (Endoscopic Mucosal Resection) is discussed, which was first described by B. Moeller in 2012. This method eliminates the need for submucosal injection by allowing mucosal lesions to float in water. It is observed through EUS (Endoscopic Ultrasound) that the muscular layer of the colon retains its circular shape and does not follow the folding of the mucosa and submucosa during peristaltic contractions. Snaring flat, depressed mucosal lesions can be challenging, but during peristaltic contractions, the lesions fold, making snaring easier. The video also presents a case of an 85-year-old male with a colonic lesion referred for ESD (Endoscopic Submucosal Dissection), where underwater EMR was successfully performed to remove the lesion while preventing deep muscle wall injury. <br /><br />(Note: No credits were mentioned in the provided transcript)
