A Prospective Trial of Aggressive Hydration Strategy to Reduce Post-ERCP Pancreatitis

Multicenter Prospective Randomized Trial of Aggressive Hydration Strategy to Reduce Post-ERCP Pancreatitis

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 510 (estimated)
• Sponsor: Dankook University · Academic / Other

• Age: 18 Years – 75 Years
• Healthy volunteers: Accepted

Summary

Postendoscopic retrograde cholangiopancreatography pancreatitis is the most frequent and serious complication of ERCP procedures, occurring in approximately 5-15% of unselected patients. Pharmacologic prevention of post-ERCP pancreatitis has been the topic of several investigations in recent years. Hydration is considered a mainstay of treatment for acute pancreatitis. We perform multicenter, prospective, randomized trial to investigate whether intravenous vigorous hydration with lactated Ringer's solution reduces the risk of post-ERCP pancreatitis. Inclusion criteria : consecutive patients older than 18 years who are scheduled to undergo diagnostic or therapeutic ERCP will be recruited. Patients will be randomly assigned in a 1:1 ratio to receive either vigorous hydration (treatment arm) or standard hydration (standard arm). Randomization will be performed in a double blinded fashion using computer-generated random numbers. Treatment arm (vigorous hydration arm); * Initial bolus of lactated Ringer's solution at 10 mL/kg over 1 hour prior to ERCP * Intravenous lactated Ringer's solution at a rate of 3 mL/kg/h during the procedure and continued for 8 hours. * At the end of ERCP, post-procedure bolus of lactated Ringer's solution at 10 mL/Kg over 1hour Standard arm (standard hydration arm); * Patients will receive lactated Ringer's solution at the start of the ERCP and the fluids will be administered at a rate of 1.5 ml/kg/h during the procedure and for 8hours after ERCP. The primary endpoint was development of post-ERCP pancreatitis, which define as increased pancreatic pain (more than 3 on a visual analogue pain scale) and hyperamylasemia (three times the upper limit of normal). The secondary endpoint included the development of asymptomatic hyperamylasemia, severity of pancreatitis, and fluid overload.

Detailed description

Postendoscopic retrograde cholangiopancreatography pancreatitis is the most frequent and serious complication of ERCP procedures, occurring in approximately 5-15% of unselected patients. Pharmacologic prevention of post-ERCP pancreatitis has been the topic of several investigations in recent years. Hydration is considered a mainstay of treatment for acute pancreatitis. We perform multicenter, prospective, randomized trial to investigate whether intravenous vigorous hydration with lactated Ringer's solution reduces the risk of post-ERCP pancreatitis. Patients will be randomly assigned in a 1:1 ratio to receive either vigorous hydration (treatment arm) or standard hydration (standard arm). Randomization will be performed in a double blinded fashion using computer-generated random numbers. Treatment arm (vigorous hydration arm); * Initial bolus of lactated Ringer's solution at 10 mL/kg over 1 hour prior to ERCP * Intravenous lactated Ringer's solution at a rate of 3 mL/kg/h during the procedure and continued for 8 hours. * At the end of ERCP, post-procedure bolus of lactated Ringer's solution at 10 mL/Kg over 1 hour Standard arm (standard hydration arm); \- Patients will receive lactated Ringer's solution at the start of the ERCP and the fluids will be administered at a rate of 1.5 ml/kg/h during the procedure and for 8hours after ERCP. The primary endpoint is development of post-ERCP pancreatitis, which define as increased pancreatic pain (more than 3 on a visual analogue pain scale) and hyperamylasemia (three times the upper limit of normal). The secondary endpoint included the development of asymptomatic hyperamylasemia, severity of pancreatitis, and fluid overload. Serum amylase levels are measured at baseline, and at 8 hours and 18-24 hours, 48 hours after the procedure. Investigators recorded the details of the maneuvers performed, including: 1. the total time of the procedure, 2. the number of attempts at cannulation, 3. the number of pancreatic duct cannulation, 4. the final diagnosis by ERCP, 5. whether a sphincterotomy, a needle-knife papillotomy, or stent placement 6. endoscopic papillary balloon dilation, 7. common bile duct (C) tissue sampling (biopsy, brush, cytology), 8. common bile duct-intraductal ultrasonography (C-IDUS), * Serum amylase is determined 8, 18\~24, and 48 hours after ERCP. * If the 12-hours serum amylase level was \> 3 times the upper normal limit and the patient exhibited pain or nausea and vomiting, then the patient had pancreatitis. * Acute pancreatitis is defined as serum amylase \> 3 times the upper limit of normal and associated with epigastric pain, back pain, and epigastric tenderness. * Statistical analysis: 1. Randomization was done by the GI nurse, concealed envelop 2. Data were summarized by descriptive statistics. 3. The Chi square was used to compare categorical patient data. 4. The Student's t test was used to compare continuous variables. 5. Two-tailed P \< 0.05 was considered to indicate significance.
