Purpose:
We evaluated the efficiency of measuring hyaluronic acid (HA) levels preoperatively in patients with injured liver disease as a predictor of complications after hepatectomy.
Methods:
We examined patients who underwent hepatectomy for liver tumors secondary to chronic viral liver diseases or obstructive jaundice.
Results:
The preoperative HA level correlated significantly with the indocyanine green retention rate at 15 min, liver activity at 15 min by technetium-99m galactosyl human serum albumin scientigraphy, and the histopathological activity index. It was also significantly elevated in patients with severe fibrosis caused by cirrhosis. After hepatectomy, the HA level was increased on postoperative day (PODS) 7, but had normalized by POD 28. The preoperative HA level tended to correlate with the regeneration rate on POD 28, and was significantly higher in patients with prolonged ascites or hepatic failure postoperatively. Multivariate analysis identified a serum HA level above 200 or 150 ng/ml as the only significant predictor of postoperative hepatic failure or long-term ascites, respectively (P < 0.05).
Conclusion:
Our findings indicate that the preoperative serum HA level is a good predictor of postoperative complications in patients who undergo hepatectomy for injured liver disease.
