The objective of this study was 10 evaluate the clinical feasibility of a new technique for liver resection based on a radiofrequency-assisted (485 kHz) device that has shown high performance in the animal setting in both transection speed and blood loss per transection area. Eight patients with colorectal hepatic metastasis underwent 11 partial hepatectomies using the proposed technique for both parenchyma division and hemostasis. Main outcome measures were blood loss per transection area and transection speed. No other instruments (including sutures or clips were used in any of the cases temporary vascular occlusion performed No blood transfusions were required and no mortality or morbidity linked to the hepatic procedure were observed. the medium blood loss per transection area and the median transection speed were 79 mL/cm(2) range 05 7.37 mL/cm(2) and 1.28 cm(2/)min range 49 1.87 mL/cm(2) respectively during the follow-up period range 4 12 late posed radiofrequency-assisted device was shown to achieve parenchymal division and hemostasis simultaneously, resulting in extremely reduced blood loss.
