The authors examined the effectiveness of extracorporeal shock-wave lithotripsy on patients who had bile-duct stones. Thirty-eight patients were treated with an unmodified HM-3 Dornier lithotripter; 35 (92%) patients either passed the stone fragments spontaneously or had them reduced to a size which allowed removal by percutaneous or endoscopic techniques. As stone size increased so did the number of shocks required for satisfactory fragmentation, the number of treatments and the rate of post-treatment manipulation. The number of stones was not as important a variable as the authors expected. Pre-treatment sphincterotomy was not always necessary and was of no benefit in terms of spontaneous passage of fragments. Complications were minor. Extracorporeal shock-wave lithotripsy of stones throughout the biliary tree is a safe, effective and invaluable adjunct in the management of bile-duct stones.
作者研究了体外冲击波碎石术对胆管结石患者的有效性。38例患者接受了未改良的HM - 3多尼尔碎石机治疗；35例（92%）患者要么自行排出结石碎片，要么结石缩小到可通过经皮或内镜技术取出的大小。随着结石尺寸的增加，实现满意碎石所需的冲击次数、治疗次数以及治疗后操作率也随之增加。结石数量并非如作者预期那样是一个重要变量。治疗前的括约肌切开术并非总是必要的，且对碎片的自然排出并无益处。并发症轻微。对整个胆管树的结石进行体外冲击波碎石术是胆管结石治疗中一种安全、有效且极为重要的辅助手段。
