Intraoperative mechanical characterization of human liver

The tissue aspiration experiment, the instrumentation for intraoperative measurements and the procedure for quantitative evaluation of the measurement results are presented. This experiment is currently used in a clinical study on the correlation between the mechanical properties of liver tissue and its histopathologic state. To date the liver of 25 patients has been tested. The results indicate a difference of 40% in the initial stiffness between peritumoral normal liver tissue and liver tumor.
