A prospective, uncontrolled trial of the use of a prototype mechanical lithotripter was performed in 116 patients at nine centers. Standard endoscopic approaches had failed to remove all stones, primarily because of large size (80% of patients). For 92% of patients, common bile duct stones were successfully captured and fragmented following the use of this lithotripter. The frequency of pancreatitis and hemorrhage was no greater than with standard endoscopic retrograde sphincterotomy, and complications unique to lithotripter use were not noted. For endoscopists skilled in therapeutic duodenoscopy, this modality should be considered in management of common bile duct stones refractory to standard techniques.
在9个中心对116例患者进行了一项关于使用原型机械碎石器的前瞻性非对照试验。标准内镜方法未能清除所有结石，主要原因是结石体积大（80%的患者）。92%的患者在使用这种碎石器后，胆总管结石成功捕获并破碎。胰腺炎和出血的发生率不高于标准内镜逆行括约肌切开术，且未发现使用碎石器特有的并发症。对于熟练掌握治疗性十二指肠镜检查的内镜医师，在处理标准技术难以治疗的胆总管结石时应考虑这种方法。
