- Abstract
Background: Drain fluid amylase is commonly used as a predictor of pancreatic fistula after pancreaticoduodenectomy (PD). This study aimed to determine the ideal cut‐off value of drain fluid amylase on postoperative day 1 (DFA1) for predicting pancreatic fistula after pancreaticogastrostomy (PG). Methods: Prospective data of 272 consecutive patients undergoing PG between 2010 and 2020 was collected and analysed to determine the postoperative pancreatic fistula (POPF) risk factors. Results: The incidence of POPF was 143 cases (52.6%). The median DFA1 in patients with POPF was significantly higher than that of patients with NO‐POPF (5483 versus 311, P < 0.001). DFA1 correlated with POPF in the area under the curve (AUC) of 0.84 (P < 0.001). When DFA1 was 2300 U/L, Youden index was the highest, with a sensitivity of 72.7% and a specificity of 82.9%. Logistic regression analysis showed that DFA1 ≥ 2300 U/L was an independent predictor of POPF (P < 0.001; OR: 12.855; 95% CI: 7.019–23.544). The AUC of DFA1 and clinically relevant postoperative pancreatic fistula (CR‐POPF) was 0.674 (P < 0.001). Conclusion: DFA1 ≥ 2300 U/L can be used as an independent predictor of POPF after PG. DFA1 ≥ 3000 U/L can predict the occurrence of CR‐POPF, when DFA1 ≥ 3000 U/L, the patients should be observed closely active for complications.
