Abstract
We described the tips of bile duct stenting and gallbladder stenting. For the master of biliary endoscopists, we should know the characteristics of many kinds of metal stents in patients with distal bile duct obstructions. In particular, whether the stent belongs to the braided type and laser cut type metal stent affects the stenting. We should know the key factors of metal stent as follows: shortening rate, axial force and radial force. Based on the detail of stent characteristics, we should place the stent across the strictures. In terms of gallbladder stenting, it is very important for successful procedure to find the bifurcation of cystic duct. After finding it, the guidewire is advanced into the gallbladder using several techniques, e.g. twist, rotation, and back and forth of guidewire.
