Aggressive hydration plus Nonsteroidal Anti-Inflammatory Drugs versus Nonsteroidal Anti-Inflammatory Drugs alone for preventing post-ERCP pancreatitis: a meta-analysis.

For ALL patients undergoing ERCP (average-risk and high-risk alike), give periprocedural rectal NSAID prophylaxis (100 mg indomethacin or diclofenac) unless contraindicated (e.g., recent PUD, renal insufficiency), this is now a strong recommendation for unselected patients, not just high-risk ones. For high-risk patients undergoing repeated or deep pancreatic-duct access or ampullectomy, add a prophylactic small-caliber pancreatic duct stent (3-5Fr, preferably 5Fr, 3-7cm, removed within 5-10 days), strong recommendation; for other high-risk scenarios (difficult cannulation, prior PEP, precut sphincterotomy without fistulotomy), PD stenting is a conditional recommendation when PD access is easily achieved. Aggressive periprocedural/postprocedural IV hydration with lactated Ringer's (20 mL/kg bolus, then 3 mL/kg/h for 8h) is a conditional suggestion for unselected patients (most practical for inpatients), and wire-guided cannulation is conditionally favored over contrast-guided to reduce PEP risk. The SVI trial (Elmunzer, Lancet 2024) found rectal indomethacin alone did NOT meet non-inferiority versus indomethacin+stent in high-risk patients (PEP 14.9% vs 11.3%), supporting continued use of the combination bundle in high-risk cases rather than dropping the stent. Post-procedure, monitor for the major complications (pancreatitis, sphincterotomy bleeding, perforation, cholangitis) and manage by type, PEP by Cotton criteria with fluids/analgesia, bleeding with repeat endoscopic hemostasis, perforation by Stapfer classification with surgical consult for Type I, and cholangitis with empiric antibiotics (Tokyo Guidelines TG18) plus biliary drainage; these complication-management elements are unchanged from ESGE 2020.
