Abstract
Abstract
Background
There is no standard method for predicting remnant liver functional reserve after hepatectomy or for monitoring it in real time.
Methods
Indocyanine green (ICG) clearance (K) was measured non-invasively and instantaneously using pulse spectrophotometry before surgery, during inflow occlusion and after hepatectomy in 75 patients who underwent anatomical liver resection for hepatocellular carcinoma (HCC).
Results
Eight patients (11 per cent) suffered liver failure and one (1 per cent) died in hospital. An estimated remnant K value of 0·090 per min was the cut-off value for liver failure. In a logistic regression model, the estimated remnant K (0·090 per min; P = 0·022) and age (65 years; P = 0·025) were significant predictors of postoperative liver failure. There was a correlation between the estimated and measured post-hepatectomy K, and between the inflow occlusion K and measured post-hepatectomy K (P < 0·001). The cut-off value of less than 0·090 per min for the estimated remnant K resulted in 88 per cent sensitivity and 82 per cent specificity for predicting liver failure.
Conclusion
Perioperative real-time monitoring of ICG-K is useful for evaluating the remnant liver functional reserve before, during and after liver resection for HCC. The estimated remnant K is a significant predictor of liver failure.
