In a patient with a mid-common bile duct stone, the traction wires of a mechanical lithotriptor snapped, resulting in lithotriptor basket impaction. Simultaneous occurrence of these two potential complications of endoscopic stone extraction is very rarely reported. Extracorporeal shock wave lithotripsy failed to fragment the stone entrapped within the impacted basket. Endoscopic intracorporeal electrohydraulic shock wave lithotripsy successfully fragmented the stone under direct visualization through a cholangioscope. The entrapped stone within the basket could subsequently be pulled into the supra-ampullary bile duct for the final fragmentation with an extra-endoscopic mechanical lithotriptor cable. The present report is the first to describe a safe and effective use of endoscopic intracorporeal electrohydraulic shock wave lithotripsy followed by extra-endoscopic mechanical lithotripsy in the management of an impacted lithotriptor basket
