The clinical study on the utility of endoscopic electrohydraulic lithotripsy of common bile duct stone

Using the cholangiofiberscope, electrohydraulic lithotripsy was performed in 20 patients with biliary tract stones. In all cases, stones were destroyed and removed without any serious complications. Since these treatments no recurrence of stones has been recognized (average 8.6 months, longest 16 mo...

Summary:Using the cholangiofiberscope, electrohydraulic lithotripsy was performed in 20 patients with biliary tract stones. In all cases, stones were destroyed and removed without any serious complications. Since these treatments no recurrence of stones has been recognized (average 8.6 months, longest 16 months). The average period of PTCD needed for the treatments was 34.3 +/- 8.1 days, and the average number of treatments needed was 1.7 +/- 1.0. The average time taken was 91 +/- 26 minutes, and the period from PTCD until hospital discharge was 39.8 +/- 6.1 days for cases of common bile duct stone, and 46.3 +/- 8.8 days for common bile duct and gall bladder stone. This period for cases of common bile duct stone is equivalent to that taken by surgical procedures in our hospital. This treatment seems to be at least as good as EST or surgery for cases of common bile duct stone. It is especially appropriate for those patients who reject surgery, are elderly, poor risks, or recurrent cases.
