Abstract Text
Intraprocedural bleeding in third-space endoscopy remains a major technical challenge, and no universal pre-sealing strategy has been established.
We present the first comparison of two electrosurgical settings for vessel pre-sealing: Forced Coagulation (FC) (Effect 0.3) in CO₂ and Swift Coagulation (Effect 3.0) in saline immersion.
In the high-impedance CO₂ environment, Forced Coagulation (Effect 0.3) successfully minimized spark formation, ensuring a safe pre-sealing effect. Conversely, in the low-impedance saline medium, Swift Coagulation achieved progressive tissue heating and successful coagulation.
Crucially, FC failed in saline due to the drop of impedance. These findings demonstrate that a similar pre-sealing outcome can be achieved with different modes across different settings, emphasizing the necessity of matching the electrosurgical setting to the procedural environment
