title: [Clinical study of liver resection with bipolar radiofrequency device: Habib 4X].
abstract: OBJECTIVE
  To assess the application value of a new radiofrequency device Habib 4X in liver resection.
  
  
  METHODS
  A retrospective study was performed during March 2010 to July 2011.Forty-four patients underwent liver resection with radiofrequency device Habib 4X and another 54 patients traditional liver resection.Intraoperative blood loss, blood transfusion, Pringle's maneuver requirement, liver parenchyma transaction time, liver function recovery, complications, mortality and recurrence were recorded.
  
  
  RESULTS
  The mean resection time was (67 ± 22) min for Habib 4X group versus (93 ± 23) min for traditional group (P = 0.000). Pringle's maneuver was required in 10 patients (22.7%) for Habib 4X group and 31 (57.4%) for traditional group (P = 0.001). The mean blocking time was (7 ± 2) vs (18 ± 6) min (P = 0.001), mean blood loss volume (243 ± 132) vs (500 ± 421) ml (P = 0.002). Postoperative recovery of liver function was better in Habib 4X group than traditional group. None developed mortality in Habib 4X group. And no resection margin recurred during a 18-month follow-up.
  
  
  CONCLUSIONS
  Bipolar radiofrequency device Habib 4X is recommended for pre-coagulation in hepatectomy. And the advantages of minimized blood loss and reduced resection time result in its lower rates of morbidity and mortality.
