title: Hepatic resections by means of electrothermal bipolar vessel device (EBVS) LigaSure V: early experience.
abstract: BACKGROUND
  Many techniques and devices are available for performing liver resection, such as clamp crushing, Cavitron Ultrasonic Surgical Aspirator (CUSA), Hydrojet and dissecting sealer, ultrasonic shears, and, more recently, electrothermal bipolar vessel sealing system (EBVS). In this prospective trial we sought to evaluate the impact of EBVS on hepatic resections.
  
  
  METHODS
  From March 2004 to December 2005, 24 patients from our consecutive liver resection series were enrolled in the present study. There were 17 males and 7 females with a mean age of 59.6 years (range = 41-80) who had colonic cancer metastases (18), hepatocarcinoma (3), angioma (2), and intrahepatic lithisasis (1). Patients were prospectively randomized to undergo liver resection via EBVS LigaSure V (12 patients, group A) or ultrasonic shears harmonic scalpel (HS) (12 patients, group B). Hepatic procedures did not differ significantly between the two groups and were as follows: right hepatectomy (2), left hepatectomy (1), bisegmentectomy (14), and segmentectomy (7).
  
  
  RESULTS
  There was no mortality in either group. The mean operative time was 136.7 min (range = 90-210) in group A and 187.9 min (range = 130-360) in group B. The Pringle maneuver was done in five patients in group A [mean time = 11.4 min (range = 6-12)] and in four patients in group B [mean time = 16 min (range = 9-26)]. The mean blood loss, total bile salts, and hemoglobin concentration from drained fluid on the second postoperative day were 205.8 vs. 506.7 ml, 0.6 vs. 1.1 mmol/L, and 1.0 vs. 2.1 g/L (p < 0.05) for groups A and B, respectively. Mean postoperative hospital stay was 6.1 vs. 7.8 days. In group B a patient who underwent right hepatectomy for colon cancer metastases had transient hepatic failure. No patients received blood transfusions in group A, while two or more blood units were administered in two cases in group B.
  
  
  CONCLUSIONS
  In the present study EBVS proved to be safe and effective for liver resection. By means of this device, statistically significant benefits concerning blood loss, total bile salts, and hemoglobin postoperative leakage were found.
