Endoscopic Submucosal Dissection (ESD) (On-Demandl) | December 2024-Lab Demo 7

Video Transcription

Video Summary

Dr. Akimoto from Keio University demonstrated the water pressure method for Endoscopic Submucosal Dissection (ESD) in the stomach. He highlighted the technique's advantages, such as better visibility and maneuverability in underwater conditions compared to conventional air conditions. The process involves injecting solution, creating a mucosal flap, and using water to achieve a clearer view of the submucosal layer. Dr. Akimoto emphasized using a cut mode over coagulation in the underwater setting to minimize bubbles and tissue shrinkage. The water pressure method is versatile, extending beyond the stomach to esophageal and colorectal regions. He noted that while most bleedings can be managed using endoscopic tools under water, major bleedings might require switching to air conditions. This method is considered useful for difficult cases like duodenal and colorectal ESD. Dr. Akimoto advised general anesthesia for esophageal procedures to reduce aspiration pneumonia risk during the process.
