    Abstract:
    BACKGROUND/AIMS: Many kinds of transection devices have been developed but there are very few reports on the effectiveness of using ultrasonically activated scalpel with a hook blade in combination with a thermo-coagulating device for hepatectomy. METHODOLOGY: We studied 533 consecutive patients who underwent hepatectomy for primary disease and for living- related liver transplantation (LRLT) donors preformed using ultrasonically activated scalpel with a hook blade along with a saline-linked radiofrequency dissecting sealer (TL group, n=215) or bipolar cautery with a saline-irrigation system (IB group, n=318). Intraoperative blood loss, operative time, postoperative laboratory data collected over a week and the incidence of postoperative complications were analyzed in accordance with the pre-existing liver conditions. RESULTS: The median operative time required to perform partial hepatectomy and hemihepatectomy in liver tumor cases was found to be significantly shorter in the TL group than in the IB group. There was no significant difference in the amount of blood loss between the 2 groups. Postoperative laboratory data was favorable and the overall complication rate after hepatectomy was 9.01%. CONCLUSIONS: Ultrasonically activated scalpel with a hook blade used in combination with a thermo-coagulation device yielded favorable intra and postoperative outcomes.
