Preoperative Biliary Drainage With Metal Versus Plastic Stents in Periampullary Cancer

Currently, routine preoperative biliary drainage (PBD) was not recommended. However, PBD is still necessary in case of patients with cholangitis or very high level of bilirubin or patients who are expected to receive delayed surgery. The aim of this clinical trial is to demonstrate non-inferiority of uncovered self-expandable metal stent to plastic stent for PBD by endoscopic retrograde cholangiopancreatography in patients with periampullary cancer undergoing curative intent pancreaticoduodenectomy.
