Prediction of postoperative decompensated liver function by technetium-99m galactosyl human serum albumin liver scintigraphy in patients with hepatocellular carcinoma complicating chronic liver disease

Background Preoperative technetium-99m galactosyl-human serum albumin (Tc-GSA) liver scintigraphy may predict postoperative decompensated liver function and its value has been investigated in patients having resection of hepatocellular carcinoma (HCC). Methods Hepatic uptake ratio of Tc-GSA (LHL15) was measured before operation in 30 patients. Postoperative complications were analysed retrospectively and compared with LHL15 values and other indicators evaluating hepatic function. Results The LHL15 of 22 patients without complications was 0.91 or more, compared with 0.90 or less in the eight patients who had complications. Multifactorial analyses showed that LHL15 and Child-Pugh grade significantly predicted postoperative complications (P < 0.0001 and P = 0.0111 respectively). LHL15 was a significant predictor of complications in patients with Child-Pugh grade B disease (n = 15, P = 0.0011). Conclusion LHL15 was a reliable preoperative indicator of the risk of major postoperative complications in patients who had resection for HCC.
