Extracorporeal Shock Wave Lithotripsy and DissolutionTherapy of Gallbladder Stones: Results of the First Year Using the Dornier GM1
Extracorporeal shock wave lithotripsy (ESWL) was applied to 219 patients with gallbladder stones under a strict protocol. Ursodeoxycholic acid (UDC) and chenodeoxycholic acid (CDC) were administered concomitantly.
Laboratory abnormalities were minimal following treatment although 2.7% of patients developed biliary pancreatitis and another 1.4% of patients developed symptomatic cystic duct obstruction and cholecystitis.
Stone-free rates increased progressively during follow-up with zero to 83% of patients becoming stone free ten to 13 months following treatment, depending upon the initial stone burden treated.
