ASGE JGES Advanced ESD | September 2022-Water Pressure Method

Video Transcription

Video Summary

The video discusses the water pressure method, a natural traction technique used in endoscopic submucosal dissection (ESD). The presenter explains that while other traction devices can be cumbersome and time-consuming to set up, the water pressure method is much simpler and only requires the use of normal saline and an ST food device. The method involves removing air from the lumen, immersing the region with normal saline, and using the irrigation channel of the endoscope to flush the saline and easily open the submucosal space. The presenter demonstrates the technique on two clinical cases, highlighting its effectiveness in achieving good visualization, reducing procedure time, and minimizing complications. The method is particularly useful in challenging cases with fibrosis or muscle traction. The presenter also provides technical tips for using different knives and addressing bleeding during the procedure.
