TWO AGED PATIENTS WITH COMMON BILE DUCT STONES (CBDS) WHO WERE SUCCESSFULLY TREATED USING EXTRACORPOREAL SHOCKWAVE LITHOTRIPSY (ESWL)

Two aged patients with common bile duct stones (CBDS) who were successfully treated by using ESWL are described.A male case of CBDS developed cholangitis for an edema at the papilla Vater by endscopic sphincterotomy (EST) and incarceration of crushed stones by ESWL, but cholangiodrainage and further ESWL made him free from stones.Another female case of CBDS had obstructive jaundice for incarceration of CBDS, and PTCD made her jaundice decreased. After the decrease of jaundice, ESWL was performed for CBDS and without EST she became stone free with dripping glyceryltrinitrate (GTN) into the bile duct.We presented those two cases, as well as the safety of this ESWL treatment.ESWL for CBDS is more recommendatory for high risk cases which are probably inoperable and cases with giant CBDS which are difficult to be removed endscopically. On the other hand, we refer the therapy for CBDS dripping GTN into the bile duct.
