Rectal NSAIDs, Pancreatic Stents or IV Fluids: What Best Prevents Post-ERCP Pancreatitis?
PEP prevention strategies requires a structured, evidence-based clinical approach. This review summarizes the key diagnostic, management, monitoring and decision points for gastroenterology and hepatology practice.

PEP prevention strategies: practical clinical approach
This page focuses on PEP prevention strategies with emphasis on decisions that change patient care, common pitfalls, and the current evidence base.
External guidance for PEP prevention strategies
Clinical takeaway: For PEP prevention strategies, decisions should integrate current guidelines, patient-specific risk, and the evidence summarized below.
Rectal NSAIDs have the widest indication
They are recommended in both average- and high-risk patients.
Pancreatic stents are targeted
They are technically demanding and particularly useful when high-risk pancreatic access has occurred.
Hydration is supportive
Aggressive hydration can help but is not appropriate for every patient and should not replace NSAIDs or careful technique.
Practical clinical algorithm
1. Give rectal NSAID unless contraindicated.
2. Assess procedural PEP risk during cannulation.
3. Place prophylactic pancreatic stent when high-risk criteria are met.
4. Use lactated-Ringer’s hydration in patients who can tolerate it.
5. Continue careful wire-guided technique.
Common mistakes to avoid
- Choosing only one strategy in a very high-risk case.
- Using a pancreatic stent as a substitute for rectal NSAID.
- Overhydrating patients with cardiac failure.
- Forgetting that failed pancreatic-stent placement can itself increase risk.
- Ignoring cannulation technique.
Trainee takeaway
The strongest PEP prevention strategy is layered rather than competitive: NSAID for most, pancreatic stent for selected high-risk patients, hydration when safe, and atraumatic technique for everyone.
Frequently asked questions
