title: High preoperative serum alanine transferase levels: effect on the risk of liver resection in Child grade A cirrhotic patients.
abstract: Despite careful selection of cirrhotic patients with hepatocellular carcinoma (HCC), liver resection remains associated with a greater risk than in patients without underlying liver disease. In this study we assessed by multivariate analysis parameters associated with in-hospital mortality and morbidity in a selected group of 108 Child-Pugh A cirrhotic patients undergoing liver resection of HCC. The overall incidences of in-hospital deaths and postoperative complications were 8.3% and 48.1%, respectively. By univariate analysis, the preoperative serum alanine transferase (ALT) level (p = 0.001) and intraoperative transfusions (p = 0.01) were significantly associated with in-hospital death; however, only the serum ALT concentration was an independent risk factor. In-hospital mortality rates in patients whose serum ALT was below 2N (twofold the upper limit of the normal value), between 2N and 4N, and more than 4N were 3.9%, 13.0%, and 37.5%, respectively. An ALT level greater than 2N was predominantly observed in patients with a hepatitis C virus infection and significantly associated with histologic features of superimposed active hepatitis. Patients with an ALT level greater than 2N experienced an increased incidence of postoperative ascites (58% versus 32%, p = 0.01), kidney failure (16% versus 0%, p = 0.0003), and upper gastrointestinal bleeding (6.4% versus 0%, p = 0.02). These results indicate that the preoperative ALT level is a reliable predictor of in-hospital mortality and morbidity following liver resection in Child-Pugh A cirrhotic patients. Cirrhotic patients with ALT > 2N should undergo only a limited resection; if a larger resection is required, those patients should be considered for nonsurgical therapy or liver transplantation.
