Over the past 8 years we have utilized various types of mechanical lithotriptors to crush common bile duct stones. The procedure was performed in 93 patients with an overall success rate of 94%. However, because many accessories were in a developmental stage, entrapment of stones was not always possible on the first attempt, and the procedure was repeated in some patients a second or third time. During the interim, while awaiting another attempt at lithotripsy, cholangitis was prevented by leaving a prosthesis in place. A variety of lithotriptor models from different manufacturers have proven effective. We recommend that endoscopists use these devices to rid the bile duct of retained stones.

    The benefits of ML are that it is widely available, it is relatively inexpensive, and it is effective. The success rates of complete stone clearance at index ERCP for ML range from 52% to 84%.20–25 However, with multiple, successive procedures (up to 3 ERCPs), the cumulative success rate reaches 90% to 98%.20,21,23

    ESWL is used for the same indications and rarely as an adjunctive or primary therapy for gallbladder stones. Several large case series have demonstrated that mechanical lithotripsy (ML) leads to complete bile duct clearance in about 80% to 90% of patients; however, 20% to 30% of patients require more than 1 procedure.11,14-24 ML is less likely to be successful with larger and impacted stones.21,24

    Stone fragmentation prior to removal may still be required. Mechanical lithotripsy is the most popular method of stone fragmentation, although intraductal electrohydraulic or laser lithotripsy and extracorporeal shock wave lithotripsy are other options [25–28]. Large diameter endoscopic balloon dilatation (EBD) immediately after ES has reduced the need for lithotripsy techniques in most patients.
