title: Laparoscopic Habib 4X: a bipolar radiofrequency device for bloodless laparoscopic liver resection.
abstract: BACKGROUND
  In recent years the progress of laparoscopic procedures and the development of new and dedicated technologies have made laparoscopic hepatic surgery feasible and safe. In spite of this laparoscopic liver resection remains a surgical procedure of great challenge because of the risk of massive bleeding during liver transection and the complicated biliary and vascular anatomy in the liver. A new laparoscopic device is reported here to assist liver resection laparoscopically.
  
  
  METHODS
  The laparoscopic Habib 4X is a bipolar radiofrequency device consisting of a 2 x 2 array of needles arranged in a rectangle. It is introduced perpendicularly into the liver, along the intended transection line. It produces coagulative necrosis of the liver parenchyma sealing biliary radicals and blood vessels and enables bloodless transection of the liver parenchyma.
  
  
  RESULTS
  Twenty-four Laparoscopic liver resections were performed with LH4X out of a total of 28 attempted resections over 12 months. Pringle manoeuvre was not used in any of the patients. None of the patients required intraoperative transfusion of red cells or blood products.
  
  
  CONCLUSIONS
  Laparoscopic liver resection can be safely performed with laparoscopic Habib 4X with a significantly low risk of intraoperative bleeding or postoperative complications.
