title: Extracorporeal shock wave lithotripsy (ESWL) of gallbladder stones: experience in Bolzano.
abstract: During a period of 24 months, 115 patients with symptomatic gallbladder stones (77 females, 38 males; median age 46 years, range 22-87) were treated by extracorporeal shock wave lithotripsy with a Lithostar Plus. Concomitant bile acid dissolution therapy (ursodeoxycholic acid + chenodeoxycholic acid 7.5 mg/kg/day each or tauroursodesoxycholic acid 5-10mg/kg/day) was administered until 3 months after total fragment clearance. Complete clearance of all fragments was obtained after 6, 9, 12, 18 and 24 months in, respectively, 30, 45, 51, 62 and 72%. Life table analysis of the subgroups showed significantly better clearance results in patients with fragments < 5mm at the first extracorporeal shock wave lithotripsy session (67%) than in patients with larger fragments (39%) (p < 0.01). Patients with solitary stones < 20mm cleared their fragments better (58%) at 12 months than those with multiple stones (49%), but the differences were not statistically significant. Stone recurrence was 6% at 1 year and was lower in patients with solitary stones (3%) than in those with multiple stones (12%). Major side effects consisted in 2 cases of mild acute pancreatits and 19% of biliary colics.
