The “problematic common bile duct stone”, which cannot be extracted primarily by routine
endoscopic methods is one of the indications for extracorporeal shock wave lithotripsy
(ESWL). We report on the successful piezoelectric lithotripsy of a large common bile
duct stone in an 86-year-old patient. Focusing was achieved by ultrasound without
problems; the resulting fragments were extracted endoscopically without difficulty.
No side effects were observed in this painless piezoelectric lithotripsy.
