Well developed endotriptor for patients with basket impaction in the distal common bile duct.
When removing bile duct stones in endoscopic retrograde cholangiopancreatography, we sometimes encounter the complication of basket impaction. In most cases, bile duct stones can be crushed with a mechanical lithotriptor. An endotriptor also is commonly used to resolve the problem of basket impaction. An endotriptor is more powerful than a mechanical lithotriptor in crushing stones. When abdominal radiography shows apparent calcified bile duct stone, it should be cautioned that the stone is sometimes too hard to be crushed, even with use of the endotriptor as well as a mechanical lithotriptor.
