Radiofrequency-assisted liver resection

Laparoscopic liver resection using radiofrequency coagulation

“…In open liver surgery, major blood loss implicates the risk of higher morbidity and mortality as well as shorter longterm survival [17,27,32,37]. In order to reduce parenchymal bleeding during the actual transection phase in open liver surgery, several measures have been described, including radiofrequency energy to create a ''zone of dessication'' prior to performing hepatic transection.…”

“…In order to reduce parenchymal bleeding during the actual transection phase in open liver surgery, several measures have been described, including radiofrequency energy to create a ''zone of dessication'' prior to performing hepatic transection. The potential advantages of radiofrequency-assisted hepatectomy might be a ''virtually bloodless'' procedure, shorter operation time, and reduced morbidity [17,27,32,37]. The RF technique cannot be used close to the liver hilum, since heat might traumatize biliary structures with subsequent bile leakage and/or abscess formation [27,28,32,37].…”

“…The use of radiofrequency energy has been described to perform liver resection safely and with minimal blood loss. However, these results are based on few studies with small patient series, in which only open surgical procedures were performed [17,27,32,37]. With improvements in technology and hepatobiliary surgery, laparoscopic liver resection has become feasible and safe.…”

“…Another group also reported low blood loss using this technique in liver resection [89]. Haemostasis is obtained only by RF thermal energy: no additional devices like stitches, knots, clips or fibrin glue are needed [10], [88], [90], [91]; it's effective also in the cirrhotic liver and the l-cm-thick of burned coagulated surface assures margins free from tumour.…”

“…The most popular devices that can facilitate liver transection include: ultrasonic dissector [10], water jet [11], radiofrequency devices [12], salinelinked cautery [13], bipolar cautery [3], and harmonic scalpel [14]. These devices are often expensive and therefore not available worldwide, especially in centers with low economic resources.…”
