Analysis of 100 consecutive hepatectomies: risk factors in patients with liver cirrhosis or obstructive jaundice.
We analyzed various pre-, intra-, and postoperative variables in 100 consecutive patients treated by hepatectomy for various malignant and benign liver diseases to identify patients at risk of developing postoperative complications. Patients were divided into three groups: those with normal liver (NL, n = 53); those with liver cirrhosis (LC, n = 32); and those with obstructive jaundice (OJ, n = 15). The overall postoperative morbidity and mortality rates were 14% and 4% (due to liver failure), respectively. In the LC group the combined presence of abnormal levels of serum hyaluronic acid (HA, > 200 ng/ml), indocyanine green retention rate at 15 minutes (ICGR15, > 15%), and hepatic uptake ratio of (99m)Tc-galactosyl human serum albumin (GSA) at 15 minutes (LHL15, < 0.9) preoperatively was found to be a risk factor with a 100% morbidity rate. Operative blood loss of more than 1000 ml in LC patients was associated with high morbidity. In the OJ group preoperative parameters were almost normal after biliary drainage, but the extent of liver resection, blood loss > 2000 ml, and high serum interleukin-6 12 hours after hepatectomy correlated with high postoperative morbidity. No morbidity or mortality was reported in the NL group, except in a single patient who received long-term intraarterial chemotherapy preoperatively. Consequently, the extent of hepatectomy should be carefully determined according to the preoperative risk factors in LC patients; and in OJ patients hepatectomy, which tends to become extensive, should be carefully performed to minimize surgical stress because preoperative factors do not help predict outcome. Furthermore, the present study revealed that a serum HA level higher than 500 ng/ml on postoperative day 1 or day 7 (or both) was a useful marker for hepatic failure.
