摘要

Stents are tubular devices made of plastic or metal.Endoscopic stenting is the most common treatmentfor obstruction of the common bile duct or of the mainpancreatic duct, but also employed for the treatment ofbilio-pancreatic leakages, for preventing post- endoscopicretrograde cholangiopancreatography pancreatitis andto drain the gallbladder and pancreatic fluid collections.Recent progresses in techniques of stent insertionand metal stent design are represented by new, fullycoveredlumen apposing metal stents. These stentsare specifically designed for transmural drainage,with a saddle-shape design and bilateral flanges, toprovide lumen-to-lumen anchoring, reducing the riskof migration and leakage. This review is an updateof the technique of stent insertion and metal stentdeployment, of the most recent data available on stenttypes and characteristics and the new applications forbiliopancreatic stents.
