Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="hpb12207-sec-0001" sec-type="section"> <title>Background</title> <p>Liver transection is considered a critical factor influencing intra‐operative blood loss. A increase in the number of complex liver resections has determined a growing interest in new devices able to 'optimize' the liver transection. The aim of this randomized controlled study was to compare a radiofrequency vessel‐sealing system with the 'gold‐standard' clamp‐crushing technique.</p> </sec> <sec id="hpb12207-sec-0002" sec-type="section"> <title>Methods</title> <p>From January to December 2012, 100 consecutive patients undergoing a liver resection were randomized to the radiofrequency vessel‐sealing system (LF1212 group; <italic>N</italic> = 50) or to the clamp‐crushing technique (Kelly group, <italic>N</italic> = 50).</p> </sec> <sec id="hpb12207-sec-0003" sec-type="section"> <title>Results</title> <p>Background characteristics of the two groups were similar. There were not significant differences between the two groups in terms of blood loss, transection time and transection speed. In spite of a not‐significant larger transection area in the LF1212 group compared with the Kelly group (51.5 versus 39 cm<sup>2</sup>, <italic>P</italic> = 0.116), the overall and 'per cm<sup>2</sup>' blood losses were similar whereas the transection speed was better (even if not significantly) in the LF1212 group compared with the Kelly group (1.1 cm<sup>2</sup>/min versus 0.8, <italic>P</italic> = 0.089). Mortality, morbidity and bile leak rates were similar in both groups.</p> </sec> <sec id="hpb12207-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The radiofrequency vessel‐sealing system allows a quick and safe liver transection similar to the gold‐standard clamp‐crushing technique.</p> </sec> </abstract>
