Summary
Drain fluid amylase (DFA) is less reliable for predicting pancreatic fistula (POPF) in high-risk pancreatoduodenectomy (HR-PD) patients. Tailored drain management based on DFA and C-reactive protein is recommended for HR-PD, while early removal is feasible for non-HR-PD.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Abdominal Surgery
Background:
- Pancreatic fistula (POPF) is a significant complication after pancreatoduodenectomy.
- The utility of drain fluid amylase (DFA) in predicting POPF and guiding drain removal in high-risk pancreatoduodenectomy (HR-PD) remains unclear.
- Developing a risk-based algorithm for drain management is crucial for optimizing patient outcomes.
Purpose of the Study:
- To develop and validate a risk-based algorithm for drain management after pancreatoduodenectomy.
- To assess the predictive value of drain fluid amylase (DFA) and other biomarkers for POPF in high-risk and non-high-risk patients.
- To establish criteria for safe and early drain removal based on patient risk stratification.
Main Methods:
- A retrospective analysis of consecutive pancreatoduodenectomies from 2019-2024 at two institutions.
- Patients were stratified into high-risk (HR-PD) and non-high-risk (non-HR-PD) groups based on the International Study Group on Pancreatic Surgery score.
- Postoperative drain fluid amylase (DFA), serum amylase/lipase, and C-reactive protein levels were analyzed on postoperative days (PODs) 1-5 to correlate with POPF development.
Main Results:
- High-risk pancreatoduodenectomy (HR-PD) patients exhibited higher POPF rates (50% vs. 9%) and worse outcomes.
- Drain fluid amylase (DFA) showed lower predictive accuracy for POPF in HR-PD on POD 1 and POD 3 compared to non-HR-PD.
- Optimal criteria for drain removal were established: POD 3 for non-HR-PD (based on DFA and serum amylase/lipase) and POD 5 for HR-PD (based on DFA and C-reactive protein).
Conclusions:
- Predictive markers for POPF are less reliable in high-risk pancreatoduodenectomy (HR-PD) patients, necessitating tailored drain management.
- An early drain removal policy is feasible for non-HR-PD patients utilizing DFA and serum amylase/lipase levels.
- In HR-PD patients, drain removal can be safely postponed until POD 5, guided by DFA and C-reactive protein levels.
