We have treated the gallbladder stone patients with Munich criterin (n=82) using Dornier MPL 9.000 lithotripter. The group A patients (n=40) had single stone and *>20mm. Follow-up was done for at least 15 months by ultrasonography.
The rate of complete clearance in the group A patients was 57.9%. On the contrary the group B patients showed the clearance rate of 13.7%. The average energy of of shockwave, treatment session and shockwave numbers in group A were 17.1±0.8kv,
1.8±1.1
and 1691±414, respectively. On the contray in group B, the average energy, treatment session and shockwave numbers were 17.2±0.4kv, 2.4±1.3 and 1891±751, respectively. The adverse effects or complications were biliary colic (28%). Arrhythmia
(6%),
pancreatitis (1%), elevation of serum transaminases (2%) and acute cholecystitis (1%). Sixteen percents of our patients received elective cholecystectomy due to frequent biliary colic.
In conclusion, our lithotripsy results are inferior to those of western countries. And taking the effectiveness of laparoscopic cholecystectomy into consideration. the indication of ESWL in gallbladder stones will be so limited in Korea.
