Liver transplantationDonorUse of Bioelectrical Impedance Analysis to Assess Liver Steatosis
Section snippets
Methods
Patients without cirrhosis undergoing liver resection for cancer from July 2005 to April 2006 underwent liver BIA, using a hand held Maltron bioelectrical impedance analyzer (Maltron International Ltd, London, UK) with tetrapolar electrodes using 2 modified autoclavable probes. The power required for the handheld BioScan 915 Bioelectrical Impedance measuring device is generated by 4 × 1.5 AA sized batteries. This generates a battery current of 50 mÅ and 0.7 mÅ. This BioScan 915 was specially
Results
Demographic data were collected from the case notes and hospital computer system (Table 1). Thirty-two patients were operated for colorectal metastases, 2 for hepatocellular cancer, and 3 for metastasis from other organ (kidney and ovary) Sixteen patients underwent hemihepetectomies, 10 underwent nonanatomic segmental resections, 3 patients had extended hepatic resections, 4 had liver biopsy (inoperable disease), and 4 patients had other miscellaneous operative treatment (radiofrequency
Discussion
In the field of liver surgery, there remains the need for a simple portable measurement of liver steatosis; the gold standard of expert histopathology is not readily available at the time of cadaver organ retrieval. In this study, the different parameters of liver BIA were measured in a standard group of noncirrhotic patients undergoing liver resection. Before exploring use of the BIA device in transplantation, we needed to see if it was possible to measure the different BIA parameters with an
