Objective To explore the relation of patient age, status of liver parenchyma, presence of markers of active hepatitis, and blood loss to subsequent death and complications in patients undergoing a similar major hepatectomy for the same disease using a standardized technique. Summary Background Data Major liver resection carries a high risk of postoperative liver failure in patients with chronic liver disease. However, this underlying liver disease may comprise a wide range of pathologic changes that have, in the past, not been well defined. Methods The nontumorous liver of 55 patients undergoing a right hepatectomy for hepatocellular carcinoma was classified according to a semiquantitative grading of fibrosis. The authors analyzed the influence of this pathologic feature and of other preoperative variables on the risk of postoperative death and complications. Results Serum bilirubin and prothrombin time increased on postoperative day 1, and their speed of recovery was influenced by the severity of fibrosis. Incidence of death from liver failure was 32% in patients with grade 4 fibrosis (cirrhosis) and 0% in patients with grade 0 to 3 fibrosis. The preoperative serum aspartate transaminase (ASAT) level ranged from 68 to 207 IU/l in patients with cirrhosis who died, compared with 20 to 62 in patients with cirrhosis who survived. Conclusion A major liver resection such as a right hepatectomy may be safely performed in patients with underlying liver disease, provided no additional risk factors are present. Patients with a preoperative increase in ASAT should undergo a liver biopsy to rule out the presence of grade 4 fibrosis, which should contraindicate this resection.
