A Simple Rapid Method for Measuring Liver Steatosis Using Bioelectrical Impedance

Background/Aim: Easy measurement of liver steatosis without pathological diagnosis may help improve donor surgery efficiency and increase the chances of organ donations. We analyzed the correlations between bioelectrical impedance (BI) in human livers, liver fat content, and pathological findings. Materials and Methods: Sixteen tumor-free liver specimens resected during elective oncological surgery were analyzed. All samples were stored in ice chilled saline before BI measurement. The BI measurement was performed using a device with the tetrapolar circuit method in which the current and voltage electrodes are independent. Liver cholesterol and triglyceride levels were investigated from the same specimen using the Soxhlet extraction method. Pathological findings were examined by counting the number of hepatocytes with fatty changes per high-power field. Results: The median liver steatosis percentage was 0.4%. The liver steatosis percentage was significantly correlated with the intrahepatic triglyceride content (r=0.82, p
