  Purpose
There is clinical uncertainty and ongoing discussion among liver surgeons regarding the optimal method of parenchymal transection in patients undergoing elective hepatic resection. While the clamp-crushing technique still represents the reference technique for routine liver resections, transection of liver parenchyma using vascular staplers may offer a new and safe technique potentially reducing intraoperative blood loss, operation time as well as peri-operative morbidity. As morbidity of patients undergoing hepatic resection remains high, approaches to lower peri-operative complications are urgently required. Due to the lack of evidence it has to be evaluated, if the technique of stapler hepatectomy decreases intraoperative blood loss as a highly relevant predictor of peri-operative complications, patients' hospital stay and finally health care expenditures. These advantages would favor stapler hepatectomy to be applied in routine liver resections. As RCTs are generally considered to generate the most valid scientific evidence on a treatment's effects, the present trial evaluates potential benefits of stapler hepatectomy in a randomized fashion.

Primary Outcome Measures:
  • Intraoperative blood loss [ Time Frame: 2.5 hours ]

Enrollment: 130
Study Start Date: January 2010
Study Completion Date: March 2012
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Clamp-Crush technique Procedure: Clamp-Crush technique
The transectional line is marked and the liver capsule is cauterized. The liver parenchyma is then crushed stepwise using a regular Pèan clamp. Vessels and bile ducts are ligated or clipped. Vessels of less than 2mm diameter are coagulated with the irrigated bipolar forceps.
Experimental: Stapler hepatectomy Procedure: Stapler hepatectomy
The transectional line is marked and the liver capsule is cauterized. For subsequent transection of the hepatic parenchyma, the liver tissue is fractured with a vascular clamp in a stepwise fashion and subsequently divided with endo GIA vascular staplers.
