Establishing a Sonographic Based Algorithm to Verify Pancreatic Stent Position Placed to Prevent Post-ERCP Pancreatitis Before Endoscopic Removal

As described above. All patients start with an ultasound-based approach to visualize pancreatic stents position. Depending on the findings, x-ray will be performed if no stent is visualized in the pancreatic duct or an esophagogastroduodenoscopy will be performed to remove the pancreatic stent and confirm sonographic findings if the pancreatic stent is displayed in situ.
