The use of an endoprothesis in a pancreatic duct is a measure to minimize the incidence and severity of Post-Endoscopic Retrograde CholoangioPancreatography Pancreatitis. In this study we will evaluate the use of a Biodegradable Endoprothesis: Archimede Fast Biodegradable Pancreatic Stent in patients with high risk of Post-Endoscopic Retrograde CholoangioPancreatography Pancreatitis.The ARCHIMEDES Fast biodegradable pancreatic stent will be placed during the Endoscopic Retrograde CholoangioPancreatography. The efficacy and the security of the device will be evaluated.
