Background

It is difficult to predict hepatic functional reserve accurately before major hepatectomy. The aim of this study was to analyse the usefulness of the future liver remnant plasma clearance rate of indocyanine green (ICGK‐F, calculated as plasma clearance rate of indocyanine green (ICGK) × proportion of the future liver remnant) in predicting death after major hepatectomy.

Method

Data on ICGK and ICGK‐F were collected prospectively and analysed retrospectively for 274 patients who underwent right hepatectomy, right trisectionectomy or left trisectionectomy for biliary cancer between 1991 and 2008. The mortality rate and incidence of postoperative complications were analysed. Patients were separated into two groups according to year of operation (85 patients operated on between 1991 and 2000; 189 from 2001 to 2008).

Results

In multiple logistic regression analyses, an ICGK‐F less than 0·05 had the strongest impact on the incidence of postoperative mortality (odds ratio 8·06; P < 0·001). The postoperative mortality rate was significantly lower in the later period (P < 0·001). In patients with an ICGK‐F value between 0·040 and 0·049, the mortality rate in the early period was 30 per cent, whereas it was only 8 per cent in the later period.

Conclusion

An ICGK‐F of 0·05 is a useful cut‐off value for predicting mortality and morbidity. With careful perioperative patient management in an experienced institution, this cut‐off value can be lowered further. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
