Tailored Hydration for the Prevention of Post-ERCP Pancreatitis

"1. Hydration with lactated Ringer's solution with rate of 3.0 milliliter(mL)/kg/hr during and after ERCP and bolus injection of 20mL/kg for 1 hour after ERCP.~2. At 4 hours after ERCP (patients with ERPD stent insertion ; 6 hours), abdominal pain and serum amylase are checked. If pain (≥ Numeric rating scale (NRS) scale 3) is absent and amylase is below 1.5 times the upper normal limit (UNL), patient starts feeding and stops hydration. If patient has any of these signs, fasting and hydration continues.~3. At 8 hours, if pain (\<NRS scale 3) is absent, patient starts feeding and stops hydration. If patient has pain (≥ NRS scale 3) and previously checked amylase or re-checked serum amylase is above 3 times the UNL, patient is regarded as post-ERCP pancreatitis and receives 3mL/kg hydration. Patient with pain (≥ NRS scale 3) and previously checked serum amylase above 1.5 times but below 3 times the UNL, serum amylase is re-checked."
