Impact of parenchymal transection by Ultracision? harmonic scalpel in elective liver surgery

摘要

BACKGROUND: Evaluation of the impact of parenchymal liver transection by Ultracision? harmonic scalpel compared to ligation on operation course and outcome of elective liver surgery. METHODS: Our retrospective study included 64 consecutive patients. Liver resection was performed either by CUSA? (Cavitron ultrasonic surgical aspirator) and ligation (group L, n = 34) or by CUSA? and Ultracision? (group UC, n = 30). RESULTS: On the basis of comparable groups of patients and types of resections, we found in group UC a highly significant reduction in operation time and duration of drainage, a significant reduction in the length of hospital stay and a tendency towards less intraoperative blood substitution compared to the standard technique. Resection time, postoperative blood substitution, biliary fistula rate, complications, reinterventions and mortality showed no significant difference. CONCLUSIONS: The dissection of the liver by CUSA? and Ultracision? proved to be a safe technique with remarkable advantages compared to the conventional technique with CUSA? and ligation.
