Pancreatitis is the most important complication of ERCP. The severity of this condition varies from mild to severe and can lead to prolonged hospitalization, surgical interventions, and even death. Several patient-related and procedure related factors have been identified that are associated with a higher risk of post-ERCP pancreatitis. So far, several methods have been proposed to avoid pancreatitis in patients at higher risk of this complication.

Several studies have shown that different drug therapies (indomethacin suppository, a sublingual nitrate tablet and the administration of intravenous Ringer's solution) each may reduce the incidence of post-ERCP pancreatitis. All these drug therapies are safe, cheap and easy to administer.

Several other studies have shown that pancreatic duct stenting (placement of a plastic tube in the pancreatic duct) is an effective intervention in preventing and reducing the severity of post-ERCP pancreatitis, especially in high-risk groups. However, there are still a few drawbacks to consider with pancreatic duct stenting: there are some difficulties with insertion of a PD stent, it is associated with a need for radiological follow-up and/or repeat endoscopy for removal, higher cost and a small but important risk of complications (e.g. stent migration).

Most of the clinical trials of pancreatic duct stenting were performed, before the results of trials of drug therapies were available. Moreover, no RCT (to the investigators knowledge) has compared the efficacy of pancreatic duct stenting in patients who already received a combination of drug therapies to prevent post-ERCP pancreatitis in high-risk patients. The purpose of this study is to determine the noninferiority of a combination of drug therapies in relation to pancreatic duct stenting to prevent post-ERCP pancreatitis in high-risk patients.

Primary Outcome Measures:
  • Post-ERCP pancreatitis [ Time Frame: 24 hours after ERCP ] [ Designated as safety issue: Yes ]
    Pancreatitis is defined as new or worsened abdominal pain and tenderness with amylase levels at least three times above the upper limit of normal at 24 hours after the procedure, requiring hospital admission or a prolongation of planned admission.

Secondary Outcome Measures:
  • Severity of acute pancreatitis according to revised Atlanta classification (Banks et al. GUT 2013) [ Time Frame: One week after ERCP ] [ Designated as safety issue: Yes ]
    Mild acute pancreatitis (No organ failure, No local or systemic complications) Moderately severe acute pancreatitis (transient organ failure that resolves within 48 h and/or Local or systemic complications without persistent organ failure) Severe acute pancreatitis (Persistent organ failure >48 h)

Estimated Enrollment: 400
