Background Post-operative pancreatic fistula (POPF) remains a critical complication after pancreatic resection. This prospective pilot study evaluates perioperative markers of pancreatitis and systemic inflammation to predict clinically relevant grade B/C-POPF (CR-POPF). Methods All patients undergoing pancreatic resection from December 2017 to April 2019 were prospectively enrolled. Surgical procedures and outcomes were correlated with perioperative blood markers. ROC analysis was performed to assess their predictive value for CR-POPF. Cut-offs were calculated with the Youden index. Results In total, 70 patients were analysed (43 pancreatoduodenectomies and 27 distal pancreatectomies). In-hospital/90-d mortality and morbidity were 5.7/7.1% ( n  = 4/ n  = 5) and 75.7% ( n  = 53). Major complications (Clavien–Dindo ≥ 3a) occurred in 28 (40.0%) patients, CR-POPF in 20 (28.6%) patients. Serum lipase (cut-off > 51U/L) and IL-6 (> 56.5 ng/l) on POD3 were significant predictors for CR-POPF (AUC = 0.799, 95%-CI 0.686–0.912 and AUC = 0.784, 95%-CI 0.668–0.900; combined AUC = 0.858, 95%-CI 0.758–0.958; all p  < 0.001). Patients with both or one factor(s) above cut-off more frequently developed CR-POPF than cases without (100 vs. 50% vs. 7.5%, p  < 0.001). This also applied for overall and severe complications ( p  = 0.013 and p  = 0.009). Conclusions Post-operative pancreatitis and inflammatory response are major determinants for development of POPF. A combination of serum lipase and IL-6 on POD3 is a highly significant early predictor of CR-POPF and overall complications, potentially guiding patient management.
