Tip 18: Snare Transection Speed During EMR

Video Transcription

Video Summary

The video discusses the concept of increasing transaction speed during EMR (endoscopic mucosal resection) to limit thermal injury to tissue. The speaker suggests squeezing the snare tightly before applying electrocautery to achieve faster transection and minimize submucosal thermal injury. They demonstrate the impact of using coagulation current versus cutting current on tissue transection speed and thermal effects. The speaker emphasizes the use of a microprocessor-controlled generator and tight snare closure to reduce differences between coagulation and cutting current. The video also mentions a randomized trial comparing currents in EMR and recommends using forced coagulation current. This summary is based on a video of the ASGE SuTab tip of the week.
