Endoscopic plastic stenting for bile duct stones: stent changing on demand or every 3 months. A prospective comparison study

In patients with bile duct stones who were treated with biliary plastic stents, the best stent management to avoid cholangitis was stent changing at defined intervals (every 3 months in the current study). The data confirmed that plastic biliary stenting may decrease stone size with a high percentage of subsequent total stone clearance.
