Description

<p>A 76-year-old woman was admitted to our hospital for removal of a common bile duct stone. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a 25mm×16mm stone in the common bile duct. When the stone was grasped with a mechanical lithotripsy basket made of Nytinol, fracture of the metal wire occurred, resulting in basket impaction. Then, a 15mm snare was inserted into the bile duct over the metal wire of the basket, and the tip of the basket was grasped with the snare. Next, the snare was pulled, and the basket became inverted and deformed in the bile duct. As a result, the stone that had been grasped by the basket was successfully released. We herein report a case in which a basket inversion technique using a snare was useful for complicated mechanical lithotripsy basket impaction.</p>
