Abstract
We have performed extracorporeal shock wave lithotripsy in 60 cases of cholecystolithiasis. Here, we report the study. A lithotripter, MPL-9000, spark systemin water, was usedd.35cases showed complete disappearance of the stone. The pure cholesterol stone was the most likely to disapper, showing 100% disappearance. In a mixed stone, or combination stone, favorable results were recognized in cases with a single stone of less than 15 mm. However, a bilirubinate stone or strong calcificated stone did not disapper. In follow-up obserbation, recurrence has been recognized in 2 cases. Concerning complications, upper abdominal pain due to extraction of a crushed fragment was seen in 18 cases. However, severe impairment of tissure, due to shock wave, such as cystic submucous hematomaor intrahepatic hematoma was not recognized. Cholecystography after the treatment became impossible in 10% of the total cases.
