Thermal coagulation therapy controls active bleeding, reduces rebleeding, and reduces short-term mortality in patients with bleeding peptic ulcers that have high-risk stigmata for rebleeding. However, the optimal settings for coagulation probes (electrocautery or heater probes) have not been well studied. Limited data and anecdotal experience have indicated lower power settings with longer duration and significant pressure on the vessel.
Using experimental models, investigators studied how the various energy settings of two different coagulation probes (a standard bipolar electrode and a prototype biplanar probe) affect tissue. Energy delivery, impedance, surface area and depth of coagulation, and cavitation were evaluated in a meat sample u…
