【 摘 要 】

Abstract Aim Drain fluid amylase concentration (DFAC) has been reported as a predictor of clinically relevant postoperative pancreatic fistula (CR‐POPF) after pancreatectomy. However, the clinical significance of measuring the total drain fluid amylase amount (DFAA) considering the daily drainage volume of CR‐POPF remains unclear. Methods Data from 216 consecutive patients who underwent pancreaticoduodenectomy (PD) (n = 126) or distal pancreatectomy (DP) (n = 90) between August 2014 and November 2020 were reviewed. All drains were closed but not suctioned. DFAA was calculated by multiplying the DFAC and daily drainage fluid volume. DFAC and DFAA were recorded on d 1 and 3 after pancreatectomy. The cutoff value of CR‐POPF was determined using the receiver operating characteristic curve. Results CR‐POPF was found in 75 patients (35%) (PD: 30%, DP: 41%, P = .111); the mortality rate was zero. The cutoff value of DFAC‐day 1 was 1757 U/L (sensitivity [SE]: 84%, specificity [SP]: 62%, and accuracy [AC]: 69%). The cutoff value of DFAA‐day 1 was 139 U (SE: 71%, SP: 72%, and AC: 71%). The cutoff value of DFAC‐day 3 was 1044 U/L (SE: 73%, SP: 79%, and AC: 78%). The cutoff value of DFAA‐day 3 was 21 U (SE: 68%, SP: 72%, and AC: 70%). Multivariate analysis indicated that a nondilated pancreatic duct and high DFAC‐day 3 were independently associated with CR‐POPF after PD, indicating that a prolonged operative duration, massive blood loss, and high DFAC‐day 3 are independently associated with CR‐POPF after DP. Conclusion DFAC is more reliable than DFAA for predicting CR‐POPF after both PD and DP.
