Abstract

In many cases where failure to remove the stone during mechanical lithotripsy occur, an emergency mechanical lithotriptor enabled the stone to be removed. Stones captured within an impacted basket are either crushed or the wires of the Dormia basket are broken to release the trapped basket. However, occasionally, emergent mechanical lithotripsy may be complicated by the impaction of a basket wire due to fracture of the traction wire during crushing of the stone. We report a novel method for retrieval of an entrapped Dormia basket fractured just outside the oral cavity during an attempt to use the emergent lithotriptor. This was done by introducing a second Dormia basket into the bile duct. After catching the knob of the impacted basket, the basket was then disengaged from the stone. The simplicity of this maneuver makes it a first line salvage technique to be used before subjecting the patient to more invasive techniques.
