Summary

Monitoring drain amylase (DA) levels after pancreaticoduodenectomy (PD) can predict pancreatic fistula (PF). Low DA levels indicate a low PF risk, guiding timely drain removal post-surgery.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Abdominal Surgery

Background:

  • Pancreatic fistula (PF) is a significant complication following pancreaticoduodenectomy (PD), impacting patient morbidity and mortality.
  • Optimal drain management strategies after PD remain unclear, necessitating further investigation.

Purpose of the Study:

  • To evaluate drain amylase (DA) levels post-PD to identify patterns associated with PF development.
  • To establish a predictive model for PF risk based on DA levels and temporal trends.

Main Methods:

  • Retrospective analysis of DA levels (POD 0-5) in 76 consecutive PD patients.
  • Correlation of DA levels with PF occurrence based on International Study Group of Pancreatic Fistula criteria.

Main Results:

  • POD 1 DA levels showed strong correlation with PF rates: >5000 U/L (100% PF), <100 U/L (2% PF).
  • In intermediate DA groups, decreasing levels by POD 3 and 5 correlated with lower PF rates (13%).
  • Normalized DA levels (<100 U/L) preceded PF in only 5% of patients, suggesting early normalization indicates low risk.

Conclusions:

  • Temporal patterns of decreasing DA levels after PD are closely linked to PF risk.
  • A proposed algorithm involves daily DA monitoring with drain removal when levels fall below 100 U/L.
  • This approach could lead to earlier drain removal, averaging 1-2 days post-surgery.
