PURPOSE: High preoperative bilirubin levels and cholangitis are associated with poor peri-operative outcomes following pancreaticoduodenectomy (PD). However, the impact of deranged preoperative aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels on immediate postoperative outcomes is relatively unexplored. We hypothesized that deranged AST and ALT lead to worse postoperative outcomes after PD. The aim of this study was to assess the factors contributing to postoperative mortality (POM) following PD, and to study the impact of deranged aminotransferases.
METHODS: This is a retrospective analysis of 562 patients. Risk factors for POM were computed using a multivariate logistic regression model.
RESULTS: The rate of POM was 3.9%. On univariate analysis, the American Society of Anaesthesiologists grades, diabetes mellitus, cardiac comorbidity, preoperative biliary stenting, elevated serum bilirubin, AST, elevated serum creatinine, clinically relevant pancreatic fistula (CRPF), and grade B+C post-pancreatectomy hemorrhage (PPH) were associated with 30-day mortality. On multivariate analysis, preoperative elevated AST was independently predictive of 30-day POM (OR = 6.141, 95%CI 2.060-18.305, p = 0.001). Other factors independently predictive of POM were elevated serum creatinine, preoperative biliary stenting, CRPF and grade B and C PPH. The ratio of AST/ALT > 0.89 was associated with 8 times increased odds of POM.
CONCLUSION: Elevated preoperative AST emerged as a predictor of 30-day POM after PD, with an 8-times increased odds of death with an AST/ALT ratio > 0.89.
