    Objectives: Postoperative pancreatic fistula (POPF) is a serious complication after pancreaticoduodenectomy (PD). Thus, identification of the risk factors for POPF is urgently needed. In this study, we aimed to identify whether arterial lactate (LCT) levels following PD might be a marker of the potential risk of POPF. Between September 2009 and December 2020, 151 patients who underwent elective PD were retrospectively enrolled. Patient characteristics, perioperative clinicopathological variables, postoperative blood biochemistry data were analyzed in univariable and multivariable analyses. Pancreatic fistula of Grade B and C was considered as POPF. Patients were divided into the POPF group (n = 33, 21.9%) and non-POPF group (n = 118, 78.1%). Higher body mass index (p = 0.017), increased estimated blood loss (p = 0.047), soft textured pancreas (p = 0.007), smaller main pancreatic duct (p = 0.016), higher LCT levels (p < 0.001), higher aspartate aminotransferase levels (p = 0.023) and higher procalcitonin levels (p = 0.024) were significantly associated with POPF. Receiver operating characteristic curve analysis revealed that 2.1 mmol/L was the optimal cut-off value of LCT (sensitivity = 78.8%, specificity = 61.2%) for predicting POPF occurrence. Univariate and multivariate analyses confirmed that an LCT of ≥2.1 mmol/L was independently associated with the risk of POPF following PD (odds ratio = 6.78, 95% confidence interval = 2.22-20.74; p = 0.001). Higher LCT is a predictive marker for POPF following PD. Copyright © 2022 IAP and EPC. Published by Elsevier B.V. All rights reserved.
