ASGE Advanced Endoscopic Lesion Resection Course | November 2022-Deep Dive on Underwater EMR

Video Transcription

Video Summary

In the video, the speaker discusses underwater endoscopic mucosal resection (EMR), a technique used to remove polyps in the colon. The speaker explains that underwater EMR is a safe and effective method that can result in faster resection time, higher on-block resection rates, and lower rates of residual adenoma compared to conventional EMR. The speaker also discusses the technique used in the procedure, which involves filling the colon with water to create better visibility and eliminate the need for submucosal injection. The speaker emphasizes the importance of not over-distending with water and keeping the lumen decompressed. They also highlight the significance of capturing a wide margin of normal tissue around the polyp, as this can contribute to higher on-block resection rates. The speaker explains different steps of the procedure, including lesion assessment, diathermic marking, capturing the lesion with a snare, cutting the polyp, managing bleeding, and performing an underwater inspection at the end of the procedure. The speaker concludes by summarizing the benefits and challenges of underwater EMR and suggesting that it is ready for widespread use in the treatment of colonic polyps.
