Reducing the incidence of post-hepatectomy hepatic complications by preoperatively applying parameters predictive of liver function

Background/purpose: To prevent or reduce hepatic complications after hepatectomy, it is important to employ preoperative predictive parameters and to determine the indications for hepatectomy. In the present study, we evaluated risk parameters in patients who underwent hepatectomy between 1994 and 2003, and selected three parameters to modify the surgical indications. Using these indications before surgery in patients who underwent hepatectomy between 2004 and 2008, we compared the prevalences of postoperative complications in the the two groups of patients. Methods: We examined 250 consecutive patients who underwent hepatectomy for liver disease [149 in 1994-2003 (termed the early period) and 101 in 2004 to 2008 (termed the later period)]. Results: In the early period, uncontrolled ascites was observed in 55 patients and hepatic failure was observed in 15 of the 149 patients. Multivariate analysis identified volume of the resected liver (≥50%), intraoperative blood loss (≥1500 ml), prothrombin activity (<70%), hyaluronic acid level (≥200 ng/ml), and LHL15 (hepatic uptake ratio of technetium-99m galactosyl human serum albumin (99mTc-GSA) (
