Use of the electrothermal bipolar vessel system ( EBVS ) in laparoscopic adrenalectomy : a prospective study . BACKGROUND Since laparoscopic adrenalectomy ( LA ) has been adopted as the gold standard for the treatment of adrenal diseases , the development of technology for vascular control and dissection manoeuvres , amongst other things , may play a pivotal role in its further improvement . We report our experience with the electrothermal bipolar vessel sealing ( EBVS ) device for LA . METHODS From January 2004 to January 2006 , 50 patients ( pts ) undergoing LA were selected and randomized for use of the EBVS ( 25 pts , group A ) versus the UltraSonic Shears ( USS ) device ( 25 pts , group B ) . Age , sex , body mass index ( BMI ) , previous surgery and associated diseases were similar between the two groups . The main surgical parameters collected for each patient ( pt ) concerned operative time , major and minor complications , conversion rate , blood loss , hospital stay and histology . RESULTS There was no mortality in either group . The right adrenalectomy mean operative time ( OpT ) was 51.8 mins ( range 40-90 mins ) and 68.6 mins ( range 50-130 mins ) in group A and B , respectively ( P not significant ) . The left adrenalectomy mean OpT was 72.2 mins ( range 55-100 mins ) and 94 mins ( range 65-140 mins ) for group A and B , respectively ( P < 0.05 ) . The mean blood loss was 83 ml ( group A ) and 210 ml ( group B ) ( p < 0.05 ) . Complications were not different for the two groups . The mean hospital stay was 2.9 and 3.1 days in group A and B , respectively ( P not significant ) . CONCLUSIONS EBVS in LA may provide a significantly short operating time and blood loss .
