The case shows the use of the VIO® 3 preciseSECT mode with HybridKnife® T-Type for the submucosal tunneling during a peroral endoscopic myotomy (POEM) performed by Dr. Honggang Yu.
“For submucosal dissection in particularly well perfused areas, for example gastric ESDs, I use preciseSECT because it provides excellent hemostasis while dissecting precisely. Larger vessels, I would usually use a Coagrasper for, are reliably coagulated. This extends the utility of ESD-knives. Quick dissection can be done by sweeping over the submucosa layer with the instrument and a continuous activation. The degree of lateral thermal spread and carbonization is minimal. This also applies for POEM-procedures.“ (Honggang Yu, MD.
