The present study is a prospective, single-center study. A total of 88 patients, who had placed a pancreatic stent for preventing post-ERCP pancreatitis, will be included in the study. Aim of the study is to establish a new algorithm based on a sonographic approach to remove the placed pancreatic stents. Another aim is to compare high-end sonographic devices with devices of medium price scale one's used on the ward.

On the day of removal of the pancreatic stent, all patients receive a sonography by an experienced investigator on the ward and by another, uninformed investigator with a high-end device. If a pancreatic stent is visualized in the pancreatic duct, the patient will have an esophagogastroduodenoscopy to remove the pancreatic stent. If sonography cannot find a pancreatic stent in the pancreatic duct an x-ray will be performed as suggested by the European and international guidelines. If the pancreatic stent spontaneously dislocated into the small bowel tract according to x-ray, no further investigation will be performed. If a stent is visulized in situ by x-ray, it will be removed by endoscopyl.

Statistical analysis will be done in cooperation with the statistical biomedical institute oft he university hospital in Frankfurt.
