title: Ultrasonically activated device for parenchymal division during open hepatectomy.
abstract: BACKGROUND
  The use of new technological devices has gained popularity and has been proposed to improve the safety of liver resection. This study was designed to evaluate the usefulness of the ultrasonically activated device (USAD) during open liver resection.
  
  
  METHODS
  Indication for surgery, type of resection, need to perform a Pringle manoeuvre, operation time, blood loss, number of blood transfusions, morbidity and mortality rate were analyzed in 60 patients undergoing a formal open liver resection by means of USAD.
  
  
  RESULTS
  The overall mean operation time was 172 minutes (range 120-255 min); an intermittent warm ischemia was applied in 9 cases (15%). The overall mean blood loss was 410 mL (median 400 mL, range 50-950 ml). A median of one blood transfusion was administered in six patients (10%). The mean hospital stay was 10.2 days (median 11, range 8-16). The overall morbidity rate was 20% (12 out of 60 patients). No in-hospital mortality was recorded. By subdividing the patients according to the presence or absence of cirrhosis no statistical significant differences were found between the two subgroups in all peri-and postoperative outcomes.
  
  
  CONCLUSIONS
  In conclusion, though there is a lack of data based on well conducted controlled studies and further on a greater number of patients are needed, the utilization of USAD may help to minimize blood loss during liver resection regardless of the condition of the liver, even in case of cirrhosis.
