[Cholecystolithotripsy using extracorporeal shock waves].
Extracorporeal shock-wave lithotripsy (ESWL) was first applied for calculi of the bile duct system in 1985. Recent improvement of the crushing apparatus has enabled us to crush the biliary calculus more accurately than before, and moreover, to conduct the procedure without anesthesia, and to treat easily. We performed ESWL in 30 cases of calculus in the cholecyst using MPL-9000 (Dornier Co., Ltd.) which is said to be a crushing device of a new generation. Here, the study is presented. The results of crushing effect demonstrate the efficacy in 26 of 30 cases (87%), and disappearance rate in 18 cases (60%) at present after an average follow-up period of 4.4 months. The disappearance cases were mainly those with a single calculus (75% disappearance rate) or pure cholesterol calculus (100%). Concerning the complications, right upper abdominal pain which was expected to accompany excretion of the crunched fragments was recognized in 10 cases (33%), it was not seen in cases in which laparotomy or endoscopic papillotomy was performed.
