Comparison of two radiofrequency-based hemostatic devices: Saline-linked bipolar vs. cooled-electrode monopolar

Purpose: To characterize the coagulation zones created by two radiofrequency (RF)-based hemostatic devices: one comprised an internally cooled monopolar electrode and the other comprised externally irrigated bipolar electrodes (saline-linked). Materials and methods: RF-induced coagulation zones were...

Materials and methods: RF-induced coagulation zones were created on ex vivo and in vivo porcine models. Computer modeling was used to determine the RF power distribution in the saline-linked device. Results: Both external (irrigation) and internal cooling effectively prevented tissue sticking. Under ex vivo conditions in 'painting' application mode, coagulation depth increased with the applied power: 2.8 - 5.6 mm with the 3-mm monopolar electrode, 1.6 - 6.0 mm with the 5-mm monopolar electrode and 0.6 - 3.2 mm with the saline-linked bipolar electrodes. Under in vivo conditions and using spot applications, the 3-mm monopolar electrode created coagulation zones of similar depth to the saline-linked bipolar electrodes (around 3 mm), while the 5-mm monopolar electrode created deeper coagulations (4.5 - 6 mm) with less incidence of popping. The presence of saline around the saline-linked bipolar electrodes meant that a significant percentage of RF power (50 - 80%) was dissipated by heating in the saline layer. Coagulation zones were histologically similar for all the tested devices. Conclusions: Both external (irrigation) and internal cooling in hemostatic RF devices effectively prevent tissue sticking and create similar coagulation zones from a histological point of view. Overall, saline-linked bipolar electrodes tend to create shallower coagulations than those created with an internally cooled monopolar electrode.Spanish Ministerio de Ciencia, Innovación y Universidades MCIN/AEI/10.13039/501100011033 [Grants RTI2018-094357-B-C21 and RTI2018-094357-B-C22], “Agencia Nacional de Promoción Científica y Tecnológica de Argentina” [PICT-2020-SERIEA-00457], Dr. Irastorza was the recipient of a scholarship from the Programa de Becas Externas Postdoctorales para Jóvenes Investigadores del CONICET (Argentina).Taylor & Francis202320232022info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://hdl.handle.net/10230/56446http://dx.doi.org/10.1080/02656736.2022.2140840reponame:Recercat.
