A bubble-free strategy for saline-immersion endoscopic submucosal dissection: optimized electrosurgical settings and continuous low-pressure saline perfusion

Key Points

• Saline-immersion endoscopic submucosal dissection shows enhanced precision with a bubble-free technique, improving surgical outcomes.
• Key evidence indicates that using low-pressure saline perfusion reduces complications during electrosurgery.
• Application of optimized electrosurgical settings leads to reduced bubble formation, improving visibility and precision during the procedure.
• This approach may enable safer and more effective endoscopic techniques, but further validation in clinical settings is necessary.
