Two different methods for donor hepatic transection : cavitron ultrasonic surgical aspirator with bipolar cautery versus cavitron ultrasonic surgical aspirator with radiofrequency coagulator-A randomized controlled trial . The aim of this study was to compare the Cavitron ultrasonic surgical aspirator ( CUSA ) with bipolar cautery ( BP ) to CUSA with a radiofrequency coagulator [ TissueLink ( TL ) ] in terms of efficacy and safety for hepatic transection in living donor liver transplantation . Twenty-four living liver donors ( n = 12 for each group ) were randomized to undergo hepatic transection using CUSA with BP or CUSA with TL . Blood loss during parenchymal transection and speed of transection were the primary endpoints , whereas the degree of postoperative liver injury and morbidity were secondary endpoints . Median blood loss during liver transection was significantly lower in the TL group than in the BP group ( 195.2 +/- 84.5 versus 343.3 +/- 198.4 mL ; P = 0.023 ) , and liver transection was significantly faster in the TL group than in the BP group ( 0.7 +/- 0.2 versus 0.5 +/- 0.2 cm ( 2 ) /minute ; P = 0.048 ) . Significantly fewer ties were required during liver transection in the TL group than in the BP group ( 15.8 +/- 4.8 versus 22.8 +/- 7.9 ties ; P = 0.023 ) . The morbidity rates were similar for the 2 groups . In conclusion , CUSA with TL is superior to CUSA with BP for donor hepatectomy in terms of blood loss and speed of transection with no increase in morbidity .
